Now, wehave moved away from the presentation of this refined and processed. Now, we havelost the patience to watch the beautiful advertising audience, after all, the advertisingsales media, exhibition, broadcast, very difficult to have as in the past, forcing theaudience had watched.Now, people can search engines and blog, like la carte as on-demand news. Peopledo not always read the story of the original, on the contrary, people can go deep intothe intermediate links, links, reading these stories. You are free to enter into a certainperson's blog, the three of you search the contents of the things this person involved inthe blog, but for such content, you know nothing about this person's blog, you canalso link more blog to other content. Now posted on the website's content is often raw,authentic things, the search engine provided by the consumer to capture thisinformation, these unrestrained, not veiled, to the point of thinking they unfoldedbefore our front. Bloggers have become a thinking experts, they are full-text excerpts,after re-arrangement and combination, and then offer to the general audience,dedicated to those willing to receive such information.Even the norms of the kind of news articles, can not get rid of the threat of thevoice of the customer. Now, many traditional media have chosen a new way, theirstories and popular blog title link to completely break the news editor of the shacklesof the wall and the ring caught. Although the official news story is statically publishedon a web page, however, the side of the page link will automatically displayinformation from the blog - the content is no editorial filter. Soon, we will be from thehand of the newspaper to see the contents of this form.Let us look at the work in public relations representative. The public relations onbehalf of young, hard-working, newspapers high in a gesture to see a fictional story,the story with his client. So he give colleagues sent an e-mail related things to tellthem, and then turned around and walked into the boss's office, told the boss the news. However, when he reach the boss's office, when his boss to remove the page, the story has long been endemic - the next in the story, already appeared threatening the blog title.Therefore, you have to do is: to ensure a true, reliable reputation. We can not control the customer comments, so be sure to keep in mind, the finished article, does not mean the end of the public relations. Our goal is to continue to win the good reputation on the basis for sustainable development.For those who do not keep their promise to businesses, the search engines so that they feel especially frightened. Let us take a look, if you spend a lot of money, engine marketing activities, there will be what kind of situation. Designed some very fine small ads on the bottom of the page that says: "click here, great." Of course, web pages, more links are from real consumers, you'd better is to make consumers happy, satisfied, otherwise, they released post will overwhelm any other paid advertising posts.We take a look at the practice and suffered a large cable company, not to mention its name, the companies often do not fulfill their service contract, the customer service very poor quality, often offensive to customers, so repeatedly, so that customersvery angry. If you have online access to this company, you will see what kind of information? We see expensive advertising, news stories from the official reports - as well as messages posted by thousands of angry customers. We are pleased to see that this company do a little hands and feet, and consumer reviews changes to their advertising and they put together, they are never likely to again spend money on online advertising.Why is there such a result? Blog written by those who complain, blame or words of praise, how will have a big impact, far more than the influence of the "Times" or "Newsweek"? The reason is that the blogger is a member of our team - and the team search for the information, the team members concerned about them through word of mouth to share these views and opinions. If certain members of the team rant, saying that a piece of software suddenly, inexplicably, on the hard drive removed, his criticism and scolding will be hundreds of other sites excerpt, and every one website has its own followers. In this way, everyone, whenever you see one such comments will immediately Click to view details - so they can know in the end destroy that personal computer which software company.Each of a traditional newspaper or magazine, has 1 000 sites corresponding to In today's media than traditional media have more freedom and an independent voice. Moreover, it can be more convenient, fast and cheap to see some new comments, so these remarks spread more widely.Must learn to adapt to such a complex, chaotic world. Must know, people have been talking about you, their words positive and profound content of the speech, and everywhere.Marketing staff ignored these remarks will be seen as cold and incompetent, and will not be able to attract attention and attention. Marketers learned how to interact with clients, learn how to participate in customer reviews, learn how to make people's comments play an active role in the learning will flourish.二、译文传统媒体和口碑永远交织在一起——(美)塞诺威兹过去,往往是专业人员为我们制作媒体广告,这些内容都是由记者撰写、经过编辑校订,最后经过精美包装而后提供的。
外文文献原稿和译文原稿1. IntroductionOver the past two decades, organizations of all types have increasingly acknowledged the importance of customer satisfaction and loyalty. The marketing literature suggests that the long term success of a firm is clearly based on its ability to rapidly respond to changing customer needs and preferences (Narver &Slater, 1990; Webster, 1992). A key motivation for the increasing emphasis on customer satisfaction is that higher customer satisfaction can lead to have a stronger competitive position resulting in higher market share and profitability (Fornell, 1992), reduced price elasticity, lower business cost, reduced failure cost, and mitigated cost of attracting new customers (Chien, Chang, & Su, 2003).The principal focus of this study is on evaluating the efficiency of customer satisfaction and loyalty (CS&L) for existing mobile phone brands in Turkish mobile phone sector. Since the early1990s, with the launch of the mobile phones, there has been a remarkable development both in their product sophistication and their rapid and widespread adoption. With more than three billion subscribers around the world, the extent of mobile phone diffusion in emerging markets has been increasingly larger than that in developed countries (Kalba, 2008). Turkey, being one of the fastest emerging market economies in the world, adopted mobile phone technology in 1994. Since then, there has been a considerable increase in the level of mobile phone ownership, where the number of mobile phone users in the country is expected to reach around70 million by the end of 2013, representing a penetration rate of over 90% (RNCOS, 2010). The significant rise in mobile phone usage can partially be attributed to the fact that Turkey has the youngest population in Western Europe. Turkey currently has the 6th largest young mobile phone user base in the world, with more than 11million subscribers underthe age of 25, providing a very lucrative market for mobile phone companies (Euro monitor International,2010). It should however be noted that the penetration in this market at present is still below the EU average, indicating that the mobile phone sector is not saturated yet, and there is still space for new investors. Currently, there exist nearly more than 10 major mobile phone companies operating in the Turkish mobile phone sector, each having a relatively large product line. As of 2010, the top five mobile phone brands were Nokia, Samsung, LG, Motorola and Sony Ericsson and together they account for nearly 75% of overall market sales. As a new comer, phone is rapidly increasing its market share, but as of the start of this study, did not have a significantly large presence. In terms of market share, Nokia has been undisputedly the market leader (36.4% of sales) with Samsung featuring second (19.5%) and LG ranking third (10.1%) (Patron Turk,2010).Commensurate to its widespread diffusion globally, there has been a growing worldwide academic interest in mobile phone usage which focuses mainly on examining its contribution to social life, user preferences and its ergonomic features (Bag chi, Kirs, & Lopez, 2008). A number of empirical studies were also conducted within the context of Turkish mobile phone sector. The topics of these studies ranged from examining motivation of use (Dedeoglu,2004; Oscan & Kodak, 2003) to mobile phone selection (Isiklar &Buyukozkan, 2007), from customer satisfaction (Turkyilmaz &Ozkan, 2007) to brand loyalty (Simsek & Noyan, 2009).The methodology used in study to evaluate the relative CS&Lefficiency of mobile phone brands is based on data envelopment analysis (DEA). The traditional DEA technique has long been utilized as an invaluable tool in the field of operations research and management science to solve problems in wide range of industries(Hu, Lai, & Huang, 2009; Lee, 2009; Lin, Lee, & Chiu, 2009) as well as in not-for-profit organizations (Mahajan, 1991; Wu, Liang, &Chen, 2009; Zhang, Huang, Lin, & Yu, 2009); but its diffusion into the field of marketing and related disciplines has been relatively slow. For instance, in the marketing field, DEA has recently been employed as a powerful tool for data analysis in measuring efficiency in retailing sector (Charnes, Cooper, Learner, & Phillips,1985; Donthu & Yoo, 1998; Keh, 2000; Keh & Chu, 2003; Thomas,Barr, Cron, &Slocum, 1998), evaluating website marketing efficiency(Shuai & Wu, 2011), benchmarking marketing productivity(Donthu, Hershberger, & Osmonbekov, 2005; Kamakura, Ratchford,& Agrawal, 1988), and measuring relative market efficiency(Murthi, Srinivasan, & Kalyanaram, 1996) or service quality(Athanassopoulos, 1997; Soteriou & Staurinides, 1997). The assessment of CS&L has always been a major research item on the agenda of researchers in the marketing and related fields, because the issue of how efficiently a firm manages its marketing processes and their relationship with their customers is central to its ability to gain competitive edge vis-à-vis its rivals. The DEA approach adopted in this study illustrates how differences in CS&L efficiency between various mobile phone brands can be ascertained empirically, and thus helps management determine proper policies and courses of action.The rest of the paper is organized as follows. Section 2 reviews the recent literature on customer satisfaction and customer loyalty studies. Section 3 provides an in-depth description of our research methodology. Section 4 presents the results of our analysis. The last section (Section 5) summarizes our findings, describes managerial implications of the study and provides the concluding remarks.2. Background literatureWhile customer satisfaction has been defined in various ways, the high-level conceptualization that appears to have gained the widest acceptance states that satisfaction is a customer’s post purchase evaluation of a product or service (Cronin & Taylor,1992; Westbrook & Oliver, 1991). Customer satisfaction is also generally assumed to be a significant determinant of repeat sales, positive word-of-mouth, and customer loyalty. It has also long been considered as one of the key antecedents of creating brand loyalty (Cronin, Brady, & Hult, 2000; Dick & Basu, 1994; Fornell,Michael, Eugene, Jaesung, & Barbara, 1996; Syzmanski & Henard,2001). Satisfied customers return and buy more, and they tell other people about their experiences, both positive and negative (Fornellet al., 1996).Building on Hirschman’s (1970) exit-voice theory, weakly dissatisfied consumers would be of primary importance to a firm. While strongly dissatisfied consumers generally choose the exit option (i.e., they leave the firm), the weakly dissatisfied customers tendto stay loyal to the firm and rather employ the voice option, which implies overt complaints as an attempt to change the firm’practices or offerings (Fornell &Wernerfelt, 1988). Thereby, proper handling of customer complaints may ensure that weakly dissatisfied consumers remain loyal, and serve as an exit barrier (Fornell,1992; Halstead & Page, 1992). The impact of loyal customers is considerable; for many industries the profitability of a firm increases proportionally with the number of loyal customers and up to 60% of sales to new customers can be attributed to the word of mouth referrals (Reichheld & Sasser, 1990).Within the existing literature on customer satisfaction research, various customer satisfaction models were developed based on a cumulative view of satisfaction. To this end, a number of customer satisfaction indices (CSIs) were designed with most prominent of those being Swedish Customer Satisfaction Barometer (SCSB), the American Customer Satisfaction Index (ACSI) and European Customer Satisfaction Index (ECSI). Of these CSIs, we employed the ECSI model as the backbone of our CS&L efficiency model in this study due to its recent popularity in the literature and its comprehensiveness in CS&L coverage. The ECSI is a structural model based on the assumptions that customer satisfaction is derived by a number of factors such as perceived quality, perceived value, expectations of customers, and image of a firm. These factors are the antecedents of overall customer satisfaction (Turkyilmaz &Ozkan, 2007). The model also estimates the results when a customer is satisfied or not. The four antecedents of customer satisfaction may also have direct effects on customer loyalty(Johnson, Gustafson, Andreessen, Lervik, & Cha, 2001). Each construct in the ECSI model is a latent construct which is operational zed by multiple indicators (Chien et al., 2003; Fornell,1992). The underlying constructs of the ECSI model are explained as follows:The image construct evaluates the underlying image of the company. Image refers to the brand name and the kind of associations customers obtain from the product/company (Andreassen &Lindestad, 1998). Martensen, Kristiansen, and Rosholt (2000)argue that image is an important dimension of the customer satisfaction model. Image is a consequence of being reliable,professional and innovative, having contributions to society, and adding prestige to its user. It is anticipated that image has a positive effecton customer satisfaction, customer expectations and customer loyalty.Customer expectations are the consequences of prior experience with the company’s products (Rotondaro, 2002). This construct evaluates customer expectations for overall quality, for product and service quality, and for fulfillment of personal needs. The customer expectations construct is expected to have a direct and positive relationship with customer satisfaction (Anderson, Fornell, &Lehmann, 1994).Perceived quality is evaluation of recent consumption experience by the market served. This construct evaluates customization and reliability of a given product or service. Customization is the degree to which a product or service meets a customer’s requirements, and reliability is the degree to which firm’s offering is reliable, standardized, and free from deficiencies. Perceived quality is expected to have a positive effect on customer satisfaction (Fornellet al., 1996).Perceived value is the perceived level of product quality relative to the price paid by customers. Perceived value is the rating of the price paid for the quality perceived and a rating of the quality perceived for the price paid (Fornell et al., 1996). Perceived value structure provides an opportunity for comparison of the firms according their price-value ratio (Anderson et al., 1994). In the model, perceived value is expected to have a positive impact on satisfaction.Customer satisfaction construct indicates how much customers are satisfied, and how well their expectations are fulfilled. This construct evaluates overall satisfaction level of customers, fulfillment of their expectations, and company’s performance versus the ideal provider.Customer loyalty is the ultimate factor in the ECSI model. Loyalty is measured by repurchase intention, price tolerance and intention to recommend products or services to others. It is expected that better image and higher customer satisfaction should increase customer loyalty.3. MethodologyThis section presents the research methodology adopted in this study. The following subsections explain the survey instrument, the data collection procedure, and the DEA model.3.1. Survey instrumentThe DEA model of CS&L, which is shown in Fig. 1, consists of the aforementioned constructs which are based on previous research and prominent theories in the field of consumer behavior. The constructs of the CS&L model are unobservable (latent) variables indirectly described by a set of observable variables which are called manifest variables or indicators. The constructs and their constituent items are shown in Table 1. The use of multiple measures for each construct increases the precision of the estimate as compared to an approach of relying on a single measure. In our CS&L efficiency model, all four antecedents of customer satisfaction and loyalty which include image, customer expectations, perceived quality and perceived value were treated as input variables, while the two constructs, namely customer satisfaction and customer loyalty were considered as output variables.The survey questionnaire was designed using a three-step process. First, the consumer behavior literature was extensively reviewed for the manifest variables. Secondly, the questionnaire items were prepared in Turkish and refined through a series of discussions with two senior marketing managers of a prominent mobile phone company and a number of experienced academics in the field of consumer behavior. Finally, the survey questionnaire was subjected to extensive pre-testing and refinement based on a pilot study of 30 mobile phone users. Feedback from this pilot study indicated that some questions were ambiguous, difficult to understand,or irrelevant for mobile phone sector. This pilot study also served as a practical exercise for interviewers. The final questionnaire contained a total of 23 items pertaining to the CS&L. These23 items appeared to have face validity as to what should be measured. All the items were measured on 10-point scales, with anchors ranging from 1 denoting a very negative view and 10indicating a very positive view. Relying on 10-point scales enables customers to make better discriminations (Andrews, 1984).译文1.介绍在过去的二十年中,所有类型的组织都越来越多地承认了客户满意度和忠诚度的重要性。
外文文献原稿和译文原稿The water level control circuit designWater source total ranks sixth in the world, per capita water resources is only a quarter of the world per capita consumption, and geographical distribution is very uneven, the vast region north of the Yangtze River, northin most parts of the medium-sized cities in the dry state, water shortage has become an important factor restricting China's economic development. Reasonable use of water resources has become an important issue for China is now facing. In order to achieve the rational use of water resources, in addition to in beefing water conservancy projects and enhance the people's awareness of water conservation efforts to improve. But more important is the application of new technical information, real-time to accurately understand and master a variety of hydrological information in order to make the right water scheduling and management, so that preventive measures to minimize water wastage . Coupled with long-standing water level measurement of water level has been an important issue in hydrology, water resources department. For the timely detection of the signs of the accident, precautionary measures in the future, economical and practical, reliable water level wireless monitoring systems will play a major role. The water level of dam safety, one of the important parameters for water drainage and irrigation scheduling, water storage, flood discharge.Provides a good foundation for the automation of monitoring, transmission and processing of the water level reservoir modernization. Need to monitor the water level in many areas of industrial and agricultural production. The site may not be able to close without the manpower to monitor, we can RMON, sitting in the control room facing the instrument can be monitored on-site, convenient and save manpower. In order to ensure the safe production of hydroelectric power station to improve power generation efficiency,Hydropower production process need to monitor the water level in the reservoir, trash rack, pressure drop and the tail water level. However, due to the different power plants with a different factual situations, have different technical requirements, and the measurement methods and location of the water level parameters and also the requirements of the monitoring equipment. This often results in the monitoring system equipment of a high degree of variety, interchangeability is not conducive to the maintenance of equipment will increase the equipment design, production, installation complexity. Therefore, on the basis of the actual situation and characteristics of the comprehensive study of hydropower water level monitoring, the use of modern electronic technology, especially single-chip technology and non-volatile memory technology, designed to develop a versatile, high reliability, easy maintenance, the applicable a variety of monitoring the environment, multi-mode automatic water level monitoring system has important practical significance. The subject according to the reservoir water level measurement needs, design a remote microcontroller water level monitoring system, the system automatically detects the water level, time processing, Data GPRS remote upload function. The design of the monitoring system will be significant savings in manpower and resources, low-power 24 hours of continuous monitoring and upload real-time control reservoir water level, to better adapt to the needs of the modern water level measurement, the safety of the dam reservoir, impoundment spillway to provide a basis.Microcontroller embedded microcontrollers are widely used in industrial measurement and control systems, intelligent instruments and household appliances. In real-time detection and automatic control of microcomputer application system, the microcontroller is often as a core component to use. The basic requirements of the water tower water level control system in the case of unattended automatic limit automatically start the motor to reach the water level in the water level in the water tower to the water tower water supply; water tower water level reached the water level upper limit is automatically off the motor to stop water supply. And unusual time to sound the alarm and troubleshooting in the water supply system at any time to ensure that the towers of the external normal water supply role. The water tower is often seen in daily life and industrial applications, water storage devices, external water supply through the control of its water level to meet the needs of its waterlevel control is universal. Regardless of socio-economic rapid water plays an important role in people's normal life and production. Once off the water, ranging from great inconvenience to the people's living standards, weight is likely to cause serious accidents and losses, and thus a higher demand of water supply system to meet the timely, accurate, safe and adequate water supply. If you still use the artificial way, the labor-intensive, low efficiency, safety is hard to guarantee the transformation of the automated control system, which must be carried out. In order to achieve sufficient amount of water, smooth water pressure, water towers, water level automatic control design low-cost, high practical value of the controller. The design uses a separate circuit to achieve high and low warning level processing, and automatic control, save energy, improve the quality of the water supply system.SCM is an integrated circuit chip, VLSI technology with data processing capability of the central processing unit CPU random access memory RAM, read only memory ROM, and a variety of I / O port and interrupt system, timers / timer other functions (which may also include a display driver circuit, pulse width modulation circuit, analog multi-channel converter, A / D converter and other circuit) integrated into a silicon constitute a small computer system. The basic features are as follows: the chip is small, but complete, SCM is one of the main features. Its internal program memory, data memory, a variety of interface circuit. Large processor speed is higher, the median more of the arithmetic unit, processing ability, but need to be configured in the external interface circuit; microcontroller clocked generally 100MHZ less suitable for small products for independent work, cited pin number from a few hundred. The application is simple, flexible, and free assembly language and C language development of SCM products. The working process of the microcontroller: microcontroller automatically complete the tasks entrusted to it, that is, single-chip implementation of the procedure for a section of the instruction execution process, the so-called directive requirements for single-chip implementation of the various operations used in the form of the command is to write down , which corresponds to a basic operation of designers assigned to it by the instruction set, an instruction; Full instructions can be executed by the microcontroller, the microcontroller instruction set, the different types of single-chip, and its instruction set is also different. So that the microcontroller canautomatically complete a specific task, the problem to be solved must be compiled into a series of instructions (these instructions must be selected microcontroller to the identification and implementation of the Directive), a collection of this series of instructions to become the program, the program need to pre- stored in the components - memory storage capabilities. Memory is composed by a number of storage units (the smallest unit of storage), like a large building has many rooms composed of the same, the instructions stored in these units, the instruction fetch unit and perform like the rooms of large buildings, each assigned to only a room number, each memory cell must be assigned to a unique address number, the address is known as the address of the storage unit, so as long as you know the address of the storage unit, you can find the storage unit that stores instructions can be removed, and then be executed. Programs are usually executed in the order, instruction program is a sequential storage, single-chip in the implementation of the program to be able to a section of these instructions out and be implemented, there must be a component to track the address of instruction where this part the program counter PC (included in the CPU), the start of program execution, endowed the address where the first instruction of the program to the PC, and then made for each command to be executed, the PC in the content will automatically increase, increase The amount is determined by the instruction length of this article may be 2 or 3, to point to the starting address of the next instruction to ensure the implementation of the instruction sequence.Microcontroller tower water level control system is the basic design requirements: inside the tower, we have designed a simple water level detection sensor used to detect the three water level, the low water level, the normal water level, water level.

It highlights the skills and knowledge needed to accurately convey the meaning and tone of the original text while preserving its cultural and literary nuances. Through a detailed analysis of the translation process, this article emphasizes the crucial role translators play in bridging the gap between languages and making English literature accessible to a global audience.IntroductionEnglish literature is a rich and diverse field encompassing a wide range of genres, styles, and themes. From classic works by Shakespeare and Dickens to contemporary novels by authors like J.K. Rowling and Philip Pullman, English literature offers something for everyone. However, for non-English speakers, accessing and understanding these works can be a challenge. This is where translation comes in.Translation is the process of rendering a text from one language into another, while striving to preserve the original meaning, tone, and style of the original work. Translating afull-length English text requires a deep understanding of both languages, as well as a keen awareness of the cultural andhistorical context in which the work was written. Additionally, translators must possess strong writing skills in order to convey the beauty and complexity of the original text in a new language.Challenges of Full-text TranslationTranslating a full-length English text poses several challenges for translators. One of the most significant challenges is capturing the nuances and subtleties of the original work. English literature is known for its rich and layered language, with intricate wordplay, metaphors, and symbolism that can be difficult to convey in another language. Translators must carefully consider each word and phrase in order to accurately convey the author's intended meaning.Another challenge of full-text translation is maintaining the author's unique voice and style. Each writer has a distinct way of expressing themselves, and a good translator must be able to replicate this voice in the translated text. This requires a deep understanding of the author's writing style, as well as the ability to adapt it to the conventions of the target language.Additionally, translators must be mindful of the cultural and historical context of the original work. English literature is deeply rooted in the history and traditions of the English-speaking world, and translators must be aware of these influences in orderto accurately convey the author's intended message. This requires thorough research and a nuanced understanding of the social, political, and economic factors that shaped the work.Skills and Knowledge RequiredTo successfully translate a full-length English text, translators must possess a wide range of skills and knowledge. First and foremost, translators must be fluent in both the source language (English) and the target language. This includes a strong grasp of grammar, syntax, and vocabulary in both languages, as well as an understanding of the cultural and historical context of the works being translated.Translators must also have a keen eye for detail and a meticulous approach to their work. Every word, sentence, and paragraph must be carefully considered and translated with precision in order to accurately convey the meaning of the original text. This requires strong analytical skills and a deep understanding of the nuances and complexities of language.Furthermore, translators must possess strong writing skills in order to craft a compelling and engaging translation. Translating a full-length English text is not simply a matter of substituting one word for another; it requires creativity, imagination, and a deep appreciation for the beauty of language. Translators mustbe able to capture the rhythm, cadence, and tone of the original work in their translation, while also adapting it to the conventions of the target language.ConclusionIn conclusion, translating a full-length English text is a complex and challenging task that requires a high level of skill, knowledge, and creativity. Translators must possess a deep understanding of both the source and target languages, as well as the cultural and historical context of the work being translated. Through their careful and meticulous work, translators play a crucial role in making English literature accessible to a global audience, bridging the gap between languages and cultures. By preserving the beauty and complexity of the original text in their translations, translators enrich our understanding of literature and bring the works of English authors to readers around the world.。

外文文献原文Development of China’s Film Industry――文章来自《国家广电总局关于加快电影产业发展的若干意见》(2004年1月8日)Some Opinions of the State Administration of Radio, Film and Television on Expediting the Development of the Film Industry(January 8th, 2004)With a view to fully implementing the spirit of the 16th CPC National Congress as well as the 3rd Session of the 16th CPC Central Committee, satisfying the requirements for reform and development of the socialist market economy, addressing the characteristics and law of the socialist spiritual construction, and carrying out the overall planning for deepening cultural reform, the following opinions are hereby put forward on expediting the development of the film industry in the light of the practical situation concerning films.Th e Situation and Tasks Concerning the Development of China’s Film Industry1. The importance and urgency of developing the film industry. Films are one of the cultural and entertaining forms popular with the general public. As one of the industries backed by new and hightechnologies and featuring high intelligence, high input and high output, the film industry has become an important and vigorous component part of, and played a significant role in, the cultural industry as a whole. To develop the film industry can be active and important in propelling the socialist spiritual construction, carrying forward the national culture and the national spirit and promoting the restructuring of the national economy. At present, the film industry reform and development are urgently required to be compatible with the institutional environment that China is improving for its socialist market economy, the growing spiritual and cultural demand of the people in the context of a well-off society, the pattern of all-round ope ning to the outside world after China’s entry into the WTO, and the new situation of rapid development of science and technology and of fierce competition in multimedia around the globe. We must establish a new concept of film development and remove all ideological and institutional obstacles and other practices against the film industry development. We must come to the full understanding that problems do exist such as neglect of the industrial nature of films, lack of market and business awareness, irrational structure of the film industry, undiversified ownership pattern, relatively low marketization level, undersupply of products, lack of vigor and competitiveness among enterprises, etc. We must fully understand that the only approach in solving all these problems lies in the acceleration of reform, innovationand development. We must be fully aware of the significant opportunities and challenges brought by the ongoing economic development and social progress to the film industry and as soon as possible, come up with a new path that satisfies the requirements of developing the socialist advanced culture and the socialist market economy.2.The guidelines and principles in developing the film industry. We must hold high the great banner of Deng Xiaoping Theory and the important thought of the "Three Represents", fully implement the spirit of the 16th CPC National Congress as well as the 3rd Session of the 16th CPC Central Committee, keep moving in the direction of advanced culture, uphold the principle of "Two Serves" (serve the people and serve socialism) and the policy of "Two Hundreds" (let a hundred flowers blossom and let a hundred schools of thought contend), carry forward the leading melody and advocate diversification. We must strengthen and improve the leadership of the Party over films. We must emancipate our minds, seek truth from facts, keep pace with the times, and make pioneering efforts in innovation. We must uphold the principle of coordinated development between the film industry and the film undertakings and between the film culture and the film economics. We must orient films towards the general public and the market, take development acceleration as the theme, innovative reform as the driving force and institutional innovation as the focal point, actively explorediverse forms in realizing the public ownership of the film industry, strengthen the macro-control, and activate the competition mechanism at the micro level. We must bring into full play the leading role of the market and the progress in science and technology, fully tap into the initiatives of the film industry forces as well as other social forces in operating films, closely follow the law of the film art and of the film market, strike a balance between social benefits and economic returns and produce more excellent works and talents, so as to continuously satisfy the spiritual and cultural demand of the general public and propel the all-round modernization of the Chinese-characterized socialist film industry.3.The goals and tasks of developing the film industry. The first two decades of the 21st Century are an important period of strategic opportunities for film industry development. We must expedite the institutional reform and innovation in the film industry and establish as soon as possible a film industry operating pattern featuring the leading role of market forces, enterprise autonomy in operation, and statutory administration by the government. We must establish a national film market system characterized by uniformity, openness, fair competition, regulation, orderliness and legal operation. We must establish a film production and operation system characterized by multiple sources of investment, diversified operation, production in diverse forms,distribution through diverse channels and development at diverse levels. We must establish a policy and legal framework and a government supervision and administration system characterized by the rule of law in public administration, scientific regulation, forceful guarantee and effective administration. It is our goal through five to ten years of development to form several large modern film enterprise groups with prominent principal businesses, quality brands, leading market roles and international competitiveness, foster and remold a vigorous and competitive group of new film market players, therefore greatly improving the film production and operation capacity, diversifying film products, upgrading film projection facilities in both urban and rural areas, securing a continuous increase of the film audience, keeping a good cycle of input and output, making the film culture flourish at large, seeing to it that the film box office revenue and the gross film production value become a new growth point in the national economy, and making China’s film industry stronger and bigger and China one of the world film powerhouses.II. Remolding the Market Players and Activating the Micro-level Operating Mechanism4. Accelerating the transformation of the state-owned film organizations. Organizations engaged in the production, distribution and projection of films are businesses in nature; they are operating entities in the filmmarket as well as important forces in developing the film industry. The state-owned film organizations should accelerate transformation, implement company-oriented reform in the light of the modern enterprise system, and through institutional innovation, perfect the corporate governance, establish market-oriented operating patterns, create name brands, revitalize their assets, improve returns and upgrade competitiveness, so as to develop into the market players that make business decisions on their own, assume sole responsibility for their profits or losses and apply self-development and self-restraint. However, during the transformation, active and steady efforts must be made to handle well the old-age insurance and medicare guarantee for the retired as well as the repositioning of the redundant personnel.5.Actively propelling the joint-stock system. We should accelerate the establishment of the modern property rights system, separate ownership from management, clarify the property rights and management responsibilities, expand financing channels, multiply the sources of investment and actively explore a mixed ownership pattern with the participation of state-owned capital, collective capital, non-public-owned capital, etc. We will encourage state-owned, private and foreign capital from outside the film industry to participate in the joint-stock transformation of film enterprises, so as to enable them to establish a modern enterprise system, increase input, adopt better management,increase the output and open new markets. We will encourage resources reorganization and capital restructuring through such forms as merger, acquisition, regrouping, alliance, etc. among film enterprise; those qualified should try to get listed in stock exchanges. However, during the transformation, we must improve the assets appraisal system to preserve and increase the value of state property.6.Expanding the intensive operation of films. We should use the market mechanism to rationally allocate film resources, promote scale and intensive operation, do away with isolated operating patterns within certain regions or the guild and form a diversified operating structure featuring the use of multimedia such as film, television, tape-recording, CDs and the Internet. We will encourage film enterprises to build large capital-connected film groups that operate across different regions, industries and ownership patterns, in a way to make the film industry stronger and bigger.7.Deepening the institutional reform within enterprises. We should deepen the institutional reform within film enterprises, accelerate institutional innovation, establish and perfect orderly and efficient mechanisms in decision-making, management and evaluation, improve the mechanism in competition incentives and restraints, and adopt the responsibility system for management goals and position targets. We should do away with the mentality of "doing nothing but wait, rely on orask for exterior support all the time", remove the concept of egalitarianism in distribution, practice the position appointment system and the labor contract system, enhance the reform of the three systems, namely the labor employment system, the cadres and personnel system and the salary and distribution system, and see to it that there are qualification-disqualification mechanism for employees, promotion-demotion mechanism for cadres, and the linking of economic returns to social distribution (or pay to performance). We should improve the systems in finance and cost management and reduce costs in production, management and expansion, so as to improve economic returns. We should actively promote effective operating systems such as the system of film producers, the system of brokers, and the project responsibility system, in a way to continuously elevate film operations. III. Readjusting the Industrial Structure and Tapping the Market Through Diversification8.Establishing a film products pattern with profit coming from multiple sources. We should fully exert the advantage of films as a content-based industry in stimulating the development of the relevant industries, change the single operating pattern under which box office is the only source of revenue for film products, and use digitized, networked and computerized technologies to spread through multimedia, develop in multi-layers, and sell through multi-channels the film originals, duplicates, derivatives andimage products, in a way to realize the multi-profit-source pattern of the industrial chain of films and tap into the overall returns of film products.9.Developing the film market in multi-levels. We should propel the rebuilding of multi-hall cinemas in urban areas, enliven the cinema market, tap the diversified mobile cinema market, expand film projection scale in both urban and rural areas, expand the TV-connected film market, operate well film channels, and use TV-based media to broaden the coverage of films. We should develop the audiovisual film market and regulate operating activities involving the issue of copyright. We should tap the Internet film market and ensure film products to gain reasonable profit on the Internet. We should cultivate the digital film market and use high and new techs to create new platforms for film production, transmission and projection, so as to bring about new market growth point. We should develop film image products and derivative products and expand brand operation of films.IV. Deepening the Reform in the Circulating System and Establishing a Modern Market System10. Introducing a competitive and open market. To enhance the unification and opening of the film market is an important task for building a modern film market system. We must abrogate all marketsegmentation provisions in the film circulating system that obstruct fair competition, set up administrative blockade or exclude non-local products and services. We must break up regional blockade and trade monopoly, actively promote the inward and outward opening of the film market, and see to it that film products and all factors can move freely and compete orderly within the whole country.11. Deepening the reform in the cinema-chain system. We should actively promote modern film circulating methods such as the cinema-chain system which features uniformity in brand as well as in film supply, operation and management. We should change the current situation wherein chained cinemas form a large number but each has a small scale, trans-provincial chain cinemas are anything but strong in terms of their extension capacity, and provincial chain cinemas are retarded by regional blockade. We should expedite the integration of chained cinemas and expand their scale. We will encourage trans-provincial chained cinemas to play the leading role, to practice close integration by assets or covenant alliances, widen financing channels, expand scale operations and conduct capital restructuring in different forms. We will encourage state-owned and private capital from both within and outside the film industry to help the formation of chained cinemas by holding or controlling their stock or by sole proprietorship, while cinemas may select chain partnership on their own. We will encourage fair competition between different cinemachains and promote prosperity and development of the film market through competition. We should actively explore the operating law, marketing methods and management experiment of chained cinemas, take close partnership as the major form of chain establishment, and uphold the goal of reducing staff and improving efficiency, conducting scale operations, increasing sci-tech content and providing quality services, in a way to create superb chains.12. Improving the operation and management of cinemas. We should actively develop modern multi-hall cinemas, accelerate the upgrading and renovation of cinema infrastructure and film projection equipment, enhance the networking and application of computerized ticket sales systems, promote star-rating management of cinemas, regulate cinema projection and services standards, strengthen guild discipline and strictly prohibit any kind of violations such as dishonest reporting or pirate projection, so as to ensure that cinema operation and management can give first place to man, be services-based and highlight trustworthiness.13. Actively cultivating market intermediary organizations. We should actively cultivate professional distribution companies whose operation is standardized, introduce modern advertising and marketing concepts, expand distribution channels, increase the impact and radiation capacity of these companies on the market, and promote the distribution and projection of homemade movies, cross-regional scale operation as well asinstitutional innovation in the circulation sector. We should perfect sales service networks and film supply outlets oriented towards urban and rural markets, make broad use of media such as broadcasting, TV, newspapers, magazines and the Internet to advertise films, improve the operating methods of the film trading market, and accelerate the circulation of new products on the market.V. Transforming Government Functions and Improving the Macro-control System14. Transforming the administrative functions of government. The administrative departments in charge of films at all levels should separate the functions of government from enterprise management and from those of institutions. These departments shall simplify their administrative procedures, transfer power to lower levels, conduct public administration in accordance with the law, and make a transition from operation to administration of films, from direct to indirect administration and from industry-inward looking to whole-society orientation. We should bring into full play the guiding and controlling role of government departments in promoting industrial development and make full use of the respective functions of the Central and local government departments in orientation guidance, policy regulation, market supervision and administration, social administration and public services, so as to conduct public administration in accordance with the law and make a honest, clean, efficient, open andtransparent government. The government departments may relax control where necessary and shall enhance administration if required.15. Formulating a long and medium-term planning for film industry development. The administrative departments in charge of films at all levels shall focus on the current situation while having the future in view, study new issues, explore new ideas, and earnestly work out the by-phase goals of as well as the long and medium-term planning for film industry development after allowing for the local and departmental situation, so as to ensure at a strategic height the sustainable development of China’s film industry.。
本科毕业论文外文参考文献译文及原文学院经济与贸易学院专业经济学(贸易方向)年级班别2007级 1 班学号3207004154学生姓名欧阳倩指导教师童雪晖2010 年 6 月 3 日目录1 外文文献译文(一)中国银行业的改革和盈利能力(第1、2、4部分) (1)2 外文文献原文(一)CHINA’S BANKING REFORM AND PROFITABILITY(Part 1、2、4) (9)1概述世界银行(1997年)曾声称,中国的金融业是其经济的软肋。
当一国的经济增长的可持续性岌岌可危的时候,金融业的改革一直被认为是提高资金使用效率和消费型经济增长重新走向平衡的必要(Lardy,1998年,Prasad,2007年)。
事实上,不久前,中国的国有银行被视为“技术上破产”,它们的生存需要依靠充裕的国家流动资金。
但是,在银行改革开展以来,最近,强劲的盈利能力已恢复到国有商业银行的水平。
但自从中国的国有银行在不久之前已经走上了改革的道路,它可能过早宣布银行业的改革尚未取得完全的胜利。
此外,其坚实的财务表现虽然强劲,但不可持续增长。
随着经济增长在2008年全球经济衰退得带动下已经开始软化,银行预计将在一个比以前更加困难的经济形势下探索。
本文的目的不是要评价银行业改革对银行业绩的影响,这在一个完整的信贷周期后更好解决。
相反,我们的目标是通过审查改革的进展和银行改革战略,并分析其近期改革后的强劲的财务表现,但是这不能完全从迄今所进行的改革努力分离。
本文有三个部分。
在第二节中,我们回顾了中国的大型国有银行改革的战略,以及其执行情况,这是中国银行业改革的主要目标。
第三节中分析了2007年的财务表现集中在那些在市场上拥有浮动股份的四大国有商业银行:中国工商银行(工商银行),中国建设银行(建行),对中国银行(中银)和交通银行(交通银行)。
引人注目的是中国农业银行,它仍然处于重组上市过程中得适当时候的后期。
第四节总结一个对银行绩效评估。
PPI和H2RA对于长期服用阿司匹林的胃溃疡患者的疗效比较摘要目的:对比研究质子泵抑制剂(PPI)和H2-受体拮抗剂(H2RA)对于长期服用小剂量阿司匹林的胃溃疡患者的疗效。
方法:将60例经过内窥镜检查患有胃溃疡并被要求持续使用小剂量阿司匹林的患者随机分为两组,一组接受PPI治疗(兰索拉唑30mg,n=30),一组接受H2RA治疗(法莫替丁40mg;如果法莫替丁在分配之前就被控制,就用雷尼替丁300mg,n=30)。
在治疗8周后对所有患者进行胃镜复查,以评判各组疗效。
幽门螺杆菌(Hp菌)的存在与否是由治疗之前的尿素呼气试验所决定的。
治疗之前和之后都要对腹部症状自评量表问卷调查和胃肠症状评估量表(GSRS)问卷调查进行比较。
结果:除了中途退出者,PPI组和H2RA组各有26位患者接受了治疗。
两组患者在年龄中位数,性别,潜在疾病,吸烟状况,幽门螺杆菌感染程度,治疗前的溃疡患病率以及病变部位这些方面并不存在明显的差别。
通过胃镜复查得出两组治疗法的不同疗效结果:PPI组中有23位患者被治愈(治愈率为88.5%),未被治愈的患者有3位;而在H2RA组中,有22位患者被治愈(治愈率为84.6%),未被治愈的患者有4位。
两组患者在治疗前的腹部症状是不一样的。
与治疗前的分值相比,治疗后的胃肠症状评估量表(GSRS)得分并没有明显的降低。
结论:PPI组和H2RA组中长期服用小剂量阿司匹林的胃溃疡患者的治愈率都超过80%,两组在疗效上并不存在明显的差距。
关键词:小剂量阿司匹林,质子泵抑制剂,H2-受体拮抗剂,胃溃疡引言随着日本人口老龄化,人们不断地增加对小剂量阿司匹林的使用来防止大脑与心肌梗塞。
日本和海外其他国家都发布了许多关于小剂量阿司匹林能预防血栓的报道。
但是,小剂量阿司匹林的使用也引起了人们对其副作用的关注,比如说会导致胃肠黏膜损害[1,2]。
据报道,口服小剂量阿司匹林(300mg或更少)会使得胃溃疡发病率增加2.6-3倍[3],胃肠道出血发病率增加1.59倍[4]。
MEASUREMENT OF TEMPERATURE AND HUMIDITY USINGSHT11/71 INTELLIGENT SENSORAssist. Prof. Grisha Spasov, PhD, BSc Nikolay Kakanakov Department of Computer Systems, Technical University – branch Plovdiv, 25, “TzankoDjustabanov” Str., 4000 Plovdiv, Bulgaria, +359 32 659 576, e-mail: gvs@tu-plovdiv.bg,kakanak@tu-plovdiv.bgKeywords: temperature and humidity measurements, intelligent sensors, distributed automation and controlThe paper discusses the advantages of intelligent sensors. It presents an SHT11/71 temperature and humidity combined sensor from Sensirion. This sensor is ideal for developing distributed embedded systems for monitoring environmental parameters.An example application using this sensor is added to present SHT11/71 in real working condition. The application is distributed system for monitoring temperature and humidity. It uses a microcontroller with integrated web server to organize the communication and management of sensors. This application is realized and tested.1. INTRODUCTIONMeasurement and control of temperature and relative humidity has significant appliance in industry, science, healthcare agriculture and controlling technological processes. These two environmental parameters strongly influence each other and it is critical in some application to measure them in parallel. Using modern technologies it is possible to combine temperature measurement element, humidity measurement element, amplifier, ADC, digital interface, calibration memory and CRC calculation logic in a single chip with very small size [1,3].Using intelligent sensors of this kind can shorten the development time and cost. Integrating ADC and amplifier into sensor’s chip allow developers to optimize sensor elements for accuracy and long-term stability. And that is not all – integrating digital interface logic simplifies connectivity and management of sensors. These advantages can reduce whole time-to-market time and even price [1,3].In presented paper we use SHT11/71 intelligent sensor from Sensirion as an example and present its advantages and measurement procedures. An example application is also presented to demonstrate its work in real conditions. This application is realized and tested.2. INTELIGENT SENSORS – SHT11/71SHT11/71 is a single chip relative humidity and temperature multi sensor module comprising a calibrated digital output. The device includes a capacitive polymer sensing element for relative humidity and a bandgap temperature sensor. Both are seamlessly coupled to a 14bit ADC and a serial interface circuit on the same chip. This results in high signal quality, a fast response time and insensitivity to external disturbances (EMC). Each SHT11/71 is individually calibrated and calibration coefficients are programmed into the OTP memory. The 2-wire serial interface and internal voltage regulation allow easy and fast system integration [1].The SHT11/71 is shown on fig. 1 [1].Combining temperature and humidity sensing elements in single unit enables precise determination of dewpoint, without incurring errors due to temperature gradients between elements. The signal amplification near the sensor allows the polymer layers to be optimized not for signal strengths, but rather for long-term stability. Performing analog-to-digital conversion “in place” makes the signal extremely insensitive to noise. A checksum generated by the chip itself is used for additional reliability. The calibration data loaded on the chip memory guarantees that humidity sensors have identical specifications and thus they are 100% replaceable [1].Some of the advanced functions of the SHT11/71 are available trough the status register. Some of them are: internal heating element; regulation of measurement resolution to optimize for precision or for fast response; End-Of-Battery (EOB) detection (low voltage detection). Status register size is 8 bits but only four of them are used [1].SHT11/71 can be connected directly to any microcontroller by means of the digital 2-wire interface. This interface is optimized for sensor readout and power consumption and is not compatible with I2C interfaces [1]. (See fig. 2)Two wires are used to transfer serial clock (SCK) and data (DATA). The SCK is used to synchronize the communication between a microcontroller and the SHT11/71. Since the interface consists of fully static logic there is no minimum frequency. The DATA tristate pin is used to transfer data in and out of the module. It changes after the falling edge and is valid on the rising edge of the SCK. During the transmission the DATA line must remain stable while SCK is high [1].Signals over the two lines during an example transmission are shown on fig. 3 [1].3. MEASUREMENT OF TEMPERATURE AND RELATIVE HUMIDITYA measurement using SHT11/71 is a two-step procedure. First, it is necessary to send command for measurement to the sensor and get the data through the digital interface. Second, it is necessary to convert data from sensor to real physical values and to calculate the temperature compensation of the humidity data [1].3.1 Sending a command and receiving dataTo initiate a transmission, a “transmission start” sequence has to be issued. It consists of a lowering of the DATA line while SCK is high, followed by a low pulse on SCK and raising DATA again while SCK is still high [1].The subsequent command consists of three address bits (only .000. is currently supported) and five command bits. The SHT11/71 indicates the proper reception of a command by pulling the DATA pin low (ACK bit) after the falling edge of the 8th SCK clock. The DATA line is released (and goes high) after the falling edge of the 9th SCK clock. Two bytes of measurement data and one byte of CRC checksum are transmitted. The µC must acknowledge each byte by pulling the DATA line low. All values are MSB first, right justified. Possible commands are: “get temperature”, “get humidity”, “change measurement resolution”, “get status register value”, “set status register value” [1].Communication terminates after the acknowledge bit of the CRC data. If CRC-8 checksum is not used the controller may terminate the communication after the measurement data LSB by keeping ACK high. The device automatically returns to sleep mode after the measurement and communication have ended. [1]3.2 Converting Output to Physical ValuesTo compensate for non-linearity of humidity sensing element and to obtain the full accuracy it is recommended to convert the readout with the following formula [1,3]:RH linear = c1 + c2 + c3.SO RH2.Coefficients c1, c2 and c3 depend only on measurement resolution. For 12bit resolution: c1= – 4, c2= 0.0405 and c3= – 2.8*10-6. For 8bit resolution: c1= – 4, c2= 0.648 and c3= – 7.2*10-4.For temperatures significantly different from 25°C the temperature coefficient of the humidity sensor should be considered [1,3]:RH true = (T°C – 25).(t1 + t2 + SO RH) + RH linear ,where t1 = 0.01 and t2 = 0.00008 for 14bit and t2 = 0.00128 for 8bit resolution [1].The bandgap PTAT (Proportional To Absolute Temperature) temperature sensor is very linear by design. Use the following formula to convert from digital readout to temperature [1,3]:Temperature = d1 + d2.SO T.Since humidity and temperature are both measured on the same monolithic chip, the SHT11/71 allows superb dewpoint measurement.4. DISTRIBUTED SYSTEM FOR MONITORING TEMPERATURE AND HUMIDITYOn the figure 4 below a functional scheme of distributed system for monitoring temperature and humidity, based on IPC@Chip is shown [2,4].The functions of the system are separated between the four main blocks, as follows [2,5]:−The internet browser assures that the system has a familiar user interface.The visualization of the monitored parameters is placed here.−The integrated Web server in conjunction with the CGI deals with the control of the remote processes and the transfer of dynamic HTML pages to the client. The real-time operating system (RTOS) of the IPC@Chip manages with the Web server’s tasks, TCP/IP communication, local peripherals, user tasks and interconnection between them.−Users’ applications and tasks, running on the controller, are used for automation purposes. In our case, this is the sensor driving and management of the SMS communication.The software of this system consists of several blocks. One block is for temperature and humidity measurement, one – for communication with the GSM gateway and sending SMS and one is for generating dynamic HTML documents with the data from the sensor.Before every measurement a software restarting of the sensor’s interface take place. After that an initialization command is sent and controller waits 11ms. After this procedure a real measurement can start. The measurement block consists of two identical parts, one – for temperature measurement and one – for humidity measurement. The microcontroller sends a command to the sensor to get data. After getting data µC normalizes and stores it in the operating memory. The two identical parts are executed sequentially and are repeated together. Between every two iterations of this cycle the task “sleeps” for about one minute to free the processor for tasks with low priority (like FTP, Web, Telnet).The communication between the controller and the sensor is trough 2-line interface (data and synchronization). A C-library based on the software interrupts of the RTOS is made for this communication. This library has the following functions:−shttransstart() – starts a transmission;−shtreset() – for restarting of the sensor;−shtinit() – initializes the sensor interface;−shtsend() – sends a command;−shtrecv() – receives data from sensor.These functions are used to control the sensor’s work trough the 2-wire interface and to get temperature and humidity data. This data is stored in the controller memory and then converted using formulas for non-linearity and temperature compensation.To see the results of the measurement the client sends a HTTP request to the web server and the server sends a HTML document as a reply. CGI is the instrument that connects the web server with the internal data on the controller. It runs as a task and do not use data received from the client, but rather uses data from the measurement block. This transfer of data is carried out with a block of shared memory. The measurement block writes data in this memory and the CGI task reads and use this data. It generates a short HTML document containing the temperature and humidity values from the last measurement.Example web document sent as a reply from the integrated web server with the results is shown on figure 5.For controlling the parallel execution of these tasks a small program is written. This program read initialization data from files on the controller memory, installs and uninstalls the CGI processes, declares a semaphore from RTOS and frees it, releases the unused memory and stops the unneeded tasks. The other purpose of this program is to allow adding a security to the project using identification and authorization [2].5. CONCLUSIONS AND FUTURE WORKIntelligent sensors with their advantages like combining temperature and humidity sensing elements, integrating ADC, amplifiers and serial interface make development of measurement systems easier. These advantages also decrease development time and cost and the size of the product. One application where these sensors find place are distributed measurement and monitoring systems like meteorological stations, HVAC systems, automotive temperature control and many others.The SHT11/71 has an address of 3bits, which in present sensors cannot be changed from “000”. This address can be used for future applications like sensor networks and adhoc sensor networks which are leading tendencies in automation and control technologies.6.
