这种改变很大程度上是由于制造成本上升、生产资源萎缩、产品生命周期缩短、制造业内竞争加剧和全球市场经济化所引起的。

本文的主要目的是：（1）提供多级供应链建模的文献综述；（2）定义这一领域未来的研究议程。

关键词：供应链，生产，分销，物流1、介绍供应链被定义为一个完整的过程，在这过程中，有一系列多元化的商业实体（例如供应商、制造商、分销商、零售商）统一协调。

整个过程包括：（1）获取原材料；（2）将原材料生产为指定产品；（3）将产品交付给零售商。

传统意义的供应链的特点是原材料顺向流动，而信息逆向反馈。

近年来，研究者和实践者首先单独地调查了整条供应链上的各个过程。

现在我们应把注意力转移，把供应链作为一个整体考虑，进而评价绩效、研究如何设计、分析整体供应链。

从实际角度研究，供应链的概念源于生产环境的一系列变化，包括生产成本的提高、生产资料的短缺、产品寿命周期的变短、生产领域竞争水平的提高和经济全球化等因素的影响。

2、供应链的概念正如上文所提，供应链是一个完整的过程，包括将原材料转变为最终产品，将产品供应给顾客的整个过程。

Quantifying the Trade Effects of Technical Barriers to Trade: Evidence from China 1. IntroductionTechnical barriers to trade（TBT）are now widespread and have increasing impacts on international trade. The spread of TBT may have some special reasons.First, it’s legitimate. The WTO members are authorized by WTO TBT/SPS Agreement to take such measures in order to protect human health, as well as animal and plant health, provided that the enforced measures are not disguised protectionism. Second, as Baldwin (1970) emphasized, ―The lowering of tariffs has, in effect, been like draining a swamp. The lower water level has revealed all the snags and stumps of non-tariff barriers that still have to be cleared away‖. Wallner (1998) considered this phenomenon as a ―law of constant protection‖, referring to perfect substitutability between tariff and none-tariff barriers in maintaining a degree of desired domestic protection.Third, with the trade liberalization process, the remaining barriers, like TBT have a more important but not a less important impact due to the ―globalization magnification effect‖, seemingly minor differences in technical norms can have an outsized effect on production and trade (Baldwin 2000). Fourth, the increasing income of importing country and consumer preference may result in a higher demand for product quality, safety and environment protection.Since the proliferation of TBT and its increasing trade-restrictive impacts, OECD (2001) drew attention to TBT and suggested more empirical research on it, becausethe quantitative analysis is an important step in the regulatory reform process and can help inform governments to define more efficient regulations. However, due to the theoretical complexity and data s carcity, TBT have been considered as ―one of the most difficult NTBs imaginable to quantify‖ （Deardorff and Stern 1997）So far, there is not a preferred quantification strategy and claims abound on both sides about―whether such restrictions tend to reduce trade by virtue of raising compliance costsor expand trade by increasing consumer confidence in the safety and quality of imported goods‖ (Maskus and Wilson 2001).Maskus and Wilson (2001), Maskus, Otsuki, and Wilson (2001), Beghin and Bureau (2001), Ferrantino (2006) and Korinek, Melatos and Rau (2008) etc provide comprehensive overviews of key economic issues relating to TBT modeling and measurement. Based on these literatures, quantification techniques can be broadly grouped into two categories. Ex-post approaches such as gravity-based econometric models tend to estimate the observed trade impact of standards. On the other hand, ex ante methods such as simulations involving the calculation of tariff equivalents are usually employed to predict the unobserved welfare impact. No approach is or can bedefinitive. Each methodology offers its own pluses and minuses, depending on a number of factors, including the nature of the technical measure, the availability of data, and the goal of measurement. (Popper et al 2004)Concerning the trade effect1, different from any other trade measures, TBT have both trade promotion and trade restriction effects. Although a unified methodology does not exist, the gravity model is most often used for the evaluation. The gravity model employs a number of different approaches to measure the TBT. The policy indices obtained by survey can be used as proxy for the severity of TBT, and direct measures based on inventory approach are incorporated too. Beghin and Bureau（2001）summarized three sources of information that can be used to assess the importance of domestic regulations as trade barriers: (i) data on regulations, such as the number of regulations, which can be used to construct various statistical indicators,or proxy variables, such as the number of pages of national regulations; (ii) data on frequency of detentions, including the number of restrictions; frequency ratios and the import coverage ratio (iii) data on complaints from the industry against discriminatory regulatory practices and notifications to international bodies about such practices. Besides the above mentioned approach, some studies try to use explicit standards requirements such as maximum residue levels too.There are a considerable number of study combined the variable for the stringency of TBT with gravity model to estimate the direction of the trade impact.Swann, Temple, and Shurmer (1996) used counts of voluntary national and international standards recognized by the UK and Germany as indicators of standard over the period1985–1991, their findings suggest that share standards positively impact exports, but had a little impact on imports; unilateral standards positively influence imports but negatively influence exports. Moenius (2004, 2006) examines the trade effect of country specific standards and bilaterally shared standards over the period 1985-1995. Both papers used the counts of binding standards in a given industry as a measure of stringency of standards.Moenius (2004) focus on 12 OECD countries and found that at aggregate level, bilaterally shared standards and country-specific standards implemented by the importing or exporting country are both trade-promoting on average. At the industry level, the only variation is that importer-specific standards have the expected negative trade effect in nonmanufacturing sectors such as agriculture. In manufacturing industries, importer-specific standards are trade promoting too. Moenius (2006) confirm the result of Moenius (2004) in that bilateral standard in EU has very strong trade promoting effect as to the trade between EU and non-EU members, but harmonization decrease the internal trade of EU. Moenius (2006) distinguish 8 EU members and 6 non-EU developed countries. So he also found that importer specific standard in EU promote trade between EU members, but depress trade between EU members and non-EU members; Exporter specific standard inside EU has little trade promoting effect ,but export specific standard of non-EU members expand their tradewith EU.The paper using frequency or coverage ratio within a gravity model framework include Fontagné, Mimouni and Pasteels (2005) and Disdier, Fontagné, and Mimouni (2007). Both of them use the frequency ratio based on notification directly extracted from the TRAINS database. Fontagné, Mimouni and Pasteels (2005) collect data on 61 product groups, including agri-food products in 2001. Their paper generalized the findings of Moenius (2004): NTMs, including standards, have a negative impact on agri-food trade but an insignificant or even positive impact on the majority of manufactured products. Moreover, they distinguish trade effects among ―suspicious products‖, ―sensitive products‖ as well as ―remaining products‖ according to the number of notifications and distinguish different country group. Based on data covering 61 exporting countries and 114 importing countries, they find that over the entire product range, LDCs, DCs and OECD countries seem to be equally affected. However, OECD agrifood exporters tend to benefit from NTMs, at the expense of exporters from DCs and LDCs. The authors account for tariff and other NTM in the model , so they also find that tariffs matter more than NTMs, particularly foragri-food products on which comparatively high tariffs are levied.Disdier, Fontagné, and Mimouni (2008) estimate the trade effect of standards and other NTMs on 690 agri-food products (HS 6-digit level). Their data covers bilateral trade between importing OECD countries and 114 exporting countries (OECD and others) in 2004. As well as a frequency index, they use a dummy variable that records whether the importing country has notified at least one NTM and ad-valorem tariff equivalent measures of NTMs as two alternative approaches to measure NTMs. They find that these measures have on the whole a negative impact on OECD imports and affect trade more than other trade policy measures such as tariffs. The tariff equivalent shows the smallest effect. When they consider different groups of exporting countries, they show that OECD exporters are not significantly affected by SPS and TBTs in their exports to other OECD countries while developing and least developed countries’ exports are negatively and significantly affected. For the subsample of EU imports, NTMs no longer influence OECD exports positively, but exports from LDCs and DCs seem to be more negatively influenced by tariffs and SPS & TBTs than that of OECD. Finally, their sectoral analysis suggests an equal distribution of negative and positive impacts of NTBs on agricultural trade.Many studies are supportive of using maximum residue levels to directly measure the severity of food safety standards within a gravity model. These studies include Otsuki, Wilson and Sewadeh (2001a, b), Wilson and Otsuki (2004b,c) Wilson,Otsuki and Majumdsar (2003), Lacovone (2003) and Metha and Nambiar（2005）. These studies tend to focus on specific cases of standards for particular products and countries. Otsuki, Wilson and Sewadeh (2001a,b) and Wilson and Otsuki (2004b) examine the trade effect of aflatoxin standards in groundnuts and other agriculturalproducts (vegetables,fruits and cereals). The first two papers covered African export data to EU members and the third paper covered 31 exporting countries (21 developing countries) and 15 importing countries(4 developing countries). All three studies show that imports are greater when the importing country imposes less stringent aflatoxin standards on foreign products. Lacovone (2003) also used MRL of aflatoxin and found that there were substantial export losses to Latin-America from the tightening of the aflatoxin standards set by Europe. Similarly, Wilson, Otsuki and Majumdsar (2003) analyze the effect of standards for tetracycline residues on beef trade and find that regardless of the exporter standards, the standards of tetracycline imposed by the importing countries have the same negative trade impact. Wilson and Otsuki (2004c) analyze MRL relating to chlorpyrifos and Metha and Nambiar（2005）analyze the impact of MRL on India’s export of four processing agri-products to 7 developed countries and yield the similar result.Since our paper focus on the trade effect of technical barrier, we will use the most suitable ex post quantification methods. Moreover, while frequency and coverage ratio can give some guidance as to the potential trade impact of a technical measure, econometric model is used to estimate its magnitude.Our paper make contributions to the current literature in the following ways: First, in contrast to the existing empirical studies which exclusively focus on developed countries TBT, this paper focuses on a developing country, China. Second, this paper has a self-constructed trade measure database based on disaggregated data covered all HS2 products, including agricultural and processing food products (HS01-24) and manufacturing products (HS25-97) so that it can identify the sectors/products with predominant negative impacts on trade. Third, tariff data, import licenses and quotas are included as additional explanatory variables, allowing the distinction between the impact of traditional trade barriers and TBT on trade. Fourth, our data covers 43 exporting countries (including 25 developing countries), it helps to distinguish the trade effect of different country groups. Fifth, in contrast to most literature relied on cross-section data1, our paper covers 9 years time series data on TBT, so we can both capture variation across products and variation within products over time, in particular the changing effects before and after China’s entry into the WTO.The rest of the paper is organized as follows. In section 2, we construct a TBT database from 1998 to 2006 and use inventory approach (frequency index and coverage ratio) to quantify the stringency of technical measures in China. In section 3, we present our regression model, discuss all the variables and describe the data. In section 4, we discuss our findings. We make some concluding remarks in section 5. 2. Quantification of TBT2.1 Measurement of NTM: Inventory approachThe inventory approach allows estimates of the extent of trade covered by NTMs or their frequency of application in specific sectors or against individual countries orgroups of countries. Bora etc (2002) reviews various approaches to quantify NTMs and give a detailed instruction on how to construct frequency index and coverage ratio as follows. The percentage of trade subject to NTMs for an exporting country j at a desired level of product aggregation is given by the trade coverage ratio:2.2 China’s NTM database: data description and methodologyFollowed the method described above, we will construct a Chinese NTMs database from 1998 to 2006 by using inventory approach. The data covered 96 HS2 digit level agricultural and manufacturing industries. First, we calculate a series of frequency index at 4-digit-level of the Harmonized System and then aggregate them into import coverage ratio at HS2. In this database, data are collected by tariff item on the application of a range of tariff and NTMs (TBT, license and import quota) against Chinese imports. The main source of the information on the trade control measures in the database is from Chinese government publications. ―Administrative Measures Regarding Impor t & Export Trade of the People's Republic of China‖ published bythe Ministry of Commerce and Custom General Administration of China provide detailed information at HS 8-digit-level on tariff and non-tariff measures.The code list of supporting documents subject to customs control provide detailed name of licenses or instruments of ratification, which helps to identify whether a tariff line product subject to a specific non-tariff barrier. Concerning the technical measures, it includes those government administrative measures for environmental protection, safety, national security and consumer interests. The code subject to TBT control remains almost the same during the 1998-2001. Specificly, the code subject to TBT in 1998 is IRFM, denoting for Import commodity inspection (I), Quarantine control release for animal, plant and thereof product (R), Import food inspection certificate (F) and Medicine inspection certificate (M). The code concerning TBT in 1999-2001 is AMPR, denoting for Import inspection and quarantine (A), Import commodity inspection (M), Import animal, plant and thereof product inspection (P) and Import food hygiene supervision inspection (R). Since 2002, the government revised the code list into details. Although there is some tiny difference between years, the new code list remains quite stable during 2002-2006 (See the code list in Annex1). The code subject to TBT is ACFIPQSWX during 2002-2005 and AFIPQSWX in 2006, each code stands for Certificate of inspection for goods inward (A), Certificate of inspection for goods inward: Civil commodity import inspection (C), Import licencing certificate for endangered species (F), Import or export permit for psychotropic drugs (I), Import permit for waste and scraps (P), Report of inspection of soundness on import medicines (Q), Import or export registration certificate for pesticides (S), Import or export permit for narcolic drugs (W), Environment control release noticefor poisonous chemicals (X).Note that our data on trade control measures do not have a bilateral dimension. TBT measures, import license and import quotas are enforced unilaterally by Chinese government and applicable to all exporting countries. When we calculate coverageratio and frequency ratio, Vi is the total value of imports in product i from the whole world and Mi indicates whether there are imports from the whole world of good i. Hence, in a specific year, NTM variables vary among different sectors but remain the same among different countries. Although we miss the bilateral dimension associated with such measures, still the exporters are differently affected by TBT measures depending on the structure of their exports in terms of products and markets.To be precise, the frequency ratio of TBT (FR-TBT) measures the proportion of product items covered by TBT measures within a product category, which varies between 0% (no coverage) and 100% (all products covered). We first count the number of HS items (defined at the 8 digit level of the HS) covered by the TBT measures and divide it by the maximum number of product items belonging to the product category (defined here at the 4-digit level of the HS). So we get the results of frequency ratio of TBT at HS4 digit level. For example, regarding HS2402 (Cigars, cheroots, cigarillos and cigarettes, of tobacco or of tobacco substitutes), there are 3 product items with codes 24021000 (Cigars, cheroots and cigarillos, containing tobacco), 24022000 (Cigarettes containing tobacco), 24029000(other). Only one of them (HS24022000) is covered by TBT measures, so the corresponding TBT frequency index equals 33.33% (1 / 3). Then we do the same at HS2 digit level.The import coverage ratio(IC-TBT) measures the proportion of affected import of the total import within a product category. Take HS17 (Sugars and sugar confectionery) as an example, there are 4 product items with code HS1701, 1702, 1703 and 1704 respectively. Only three of them (except HS1703) are covered by TBT measures (it means the frequency index for HS1703 equals 0, while the other three are between 0 and 100%), the import value of the TBT affected products sum up to 111.216 million US$, the import valued of HS17 is 182.244 million US$, so the corresponding TBT import coverage ratio equals 66.46% (111.216/182.244).2.3 TBT rocked sectors in ChinaBy calculating frequency index and import coverage ratio of TBT, we can examine which products are the most affected. According to the definition by UNCTAD (1997), those with a frequency ratio and coverage ratio both above 50% are TBT rocked product. In our sample, 34 products（HS01-24; HS30,31,33; HS 41;HS 44-47; HS51 and HS72）are TBT-rocked during the period from 1998-2002. In 2003, two product items (HS 42-43) become TBT-rocked. In 2004, two more products (HS 50 and HS80) added into the category. During 2005-2006, HS78 are included asTBT-rocked products but HS50 is excluded. See Annex2 for the detailed product information of TBT rocked products.There are a significant number of products, particularly agricultural products and processing food widely affected by technical measures (HS01-24). However, enforcement of TBT is not limited to those products, but is spreading to manufacturing products also. The TBT rocked manufacturing products includePharmaceutical products（HS30, Essential oils, perfumes, cosmetics, toiletries (HS33), Raw hides and skins, leather, furskins and articles thereof (HS41-43), Wood and articles of wood（HS44-46）, Base metals and articles thereof, like iron and steel, aluminium and tin.( HS72, 76 and 80) etc. They are either labor intensive products or final goods concerning consumer safety, like medicaments in particular. Although TBT rocked sectors cover about 1/3 of total number of products at HS2 digit level, the proportion of affected trade is limited: about 10-16% of total import. However technical barriers are the most frequent type of NTM, the import subject to TBT account for above 90% of Chinese total import except for the rare case in 2001 (77.29%). (see Table 1).3. Model, methodology and data3.1 Model specificationWe use gravity model to examine how TBT imposed by China influence the country’s bilateral trade. To capture the size effect, population of both countries is used as proxy for exporting country’s supply capacities and importing country’s demand capacity. Per capita income of the two countries is included because higher income countries trade more in general. Transport costs are measured using the bilateral distance countries’ cultural proximity. We therefore control for this p roximity by introducing a common language dummy variable. Based on the typical gravity model, we introduce our key variables—tariff and non-tariff trade barriers. Our basic regression model takes the following forms:4. Empirical results4.1 The whole sample resultsTable 2-1 shows the summary statistics of our key variables. Table 2-2 reports the Pearson coefficients of the trade control measure variables. For the frequency index, import license and tariff appear to be negatively correlated. For the coverage ratio, besides import license, TBT seems to be slightly negative correlated with the tariff. Except for the above rare cases, the import control policies are positively correlated to each other. In general, different kinds of import control measures in China seem to be complementary to each other. Among them, import license and import quota have the highest positive coefficient, this accords with the fact that these two measures are sometimes combined together. Normally a country will distribute quota by issuing import license.We use OLS to estimate the gravity model. Regressions are run on pooled data for 9 years (see Table 3 and 4) and on data for each year separately (see Table 5 and 6). Table 3 and 5 report the result using frequency index, while Table 4 and 6 report the result using coverage ratio, both at HS 2-digit-level. For the whole sample regression results in Table 3 and 4, column 1 shows the result of the basic gravity model, column 2 introduces tariff and non-tariff barriers, column 3 tries to identify the difference between developing and developed countries and column 4 adds WTO as an additional control variable. Year-country-product fixed effect is used for all thespecifications.The results for standard gravity explanatory variables are consistent with prior expectations except for Contig as a rare case. The effect of GDPPC, POP and dist is positive and highly significant for all regressions. It implies that a 1 percent increase in the population of exporting country yields a 1.39-1.47 percent increase in the bilateral trade, and a 1 percent increase in the per capita GDP of exporting country yields a 0.91-1.40 percent increase in the bilateral trade. A 1 percent increase in geographic distance between the two trade partners will result a 1.42-1.45 percent decrease in bilateral trade. The effect of POPchina and GDPPCchina is positive and significant in two regressions. If Chinese population or per capita GDP increase 1 percent, Chinese import will increase 10.8-14.1 percent or 2.0-2.8 percent respectively. The coefficient for Comlang is positively significant in all specifications, which implies that if the exporting country share a same language with China, Chinese import will be stimulated by 2.6-3.3 percent. If the exporting market belongs to China, it will increase Chinese import by 0.3 percent. The coefficient for Contig is significantly negative, which implies that if the exporting country and China are contiguous, Chinese import will decrease 0.76-0.99 percent. This result is not consistent to the prior expectation. But the intuition is easily understood because the most important importing markets such as the US, Japan, EU members are not contiguous with China mainland.We then discuss the key explanatory variable, Tariff have a significant negative effect on Chinese import. A 1 percent increase in the MFN tariff will decrease import value by 0.64-0.66 percent. The results of the frequency index of NTM are all significant. A 1 unit increase in FRTBT will decrease import value by 1.1%, a 1 unit increase in FRQ will decrease import value by 1.7%, a 1 unit increase in FRL will increase import value by 4.1%. The results of the coverage ration of NTM are different in some extent with that of frequency index. A 1 unit increase in ICTBT will increase import value by 0.2%, a 1 unit increase in ICL will increase the import value by 2.7%, and the coefficient for ICQ is negative but not statistically significant.Table 5 and 6 give us a clear picture about how the effect of trade control measures change yearly. Tariff remains negatively significant for all 9 years.Moreover, the elasticity for Tariff dramatically increased since 2003. The trade depressing effect of Tariff nearly doubled after China’s entry into the WTO. FRTBT is negatively significant in all year specifications, and the coefficient remains stable through the sample period. FRL is positively significant while FRQ is negatively significant except for three years. In 1998, 1999 and 2001, FRL is insignificant while FRQ is positively significant due to the multicollinearity1. The result of ICTBT is changeable during the sample period. The coefficient of ICTBT is positively significant during 1998-2002, negatively significant in 2003 and insignificant during the remaining years. ICL remains positively significant during all 9 years, plus the elasticity for ICL slightly increased since 2002. ICQ is significant during 1998-2002,but the sign of the coefficient is changeable, and ICQ becomes insignificant since 2003. So ICQ doesn’t affect bi lateral trade value in a systematic way. From the yearly result, we observe that some of the trade control measure change trade patterns in a different way. Does the trade effect change significantly before and after China entry into the WTO? Whether there is any systematic difference in the trade effect between developing and developed countries? To solve these two problems, we add two interactions. Column 5 introduces the interaction between Developing and each of frequency indices of trade measures. Column 6 adds the interaction between WTO and each of coverage ratios of trade measure. As we can see, tariff (Tariff) and import quota (FRQ and ICQ) seem to have no difference between difference country groups. The change of FRTBT will affect Chinese import from developing countries less than that from developed countries. The change of ICTBT will affect Chinese import from developing countries more than that from developed countries. The change in FRL or ICL will have less impact on Chinese import from developing countries than from developed countries. On average, tariff, license have an increasing effect but quota has a decreasing effect after China’s entry into the WTO. The effect of TBT does not change significantly.5. ConclusionThe results of current literature suggest that TBT in importing country has restrictive trade effect and exports of poor countries are affected more. The paper explores whether technical measures imposed by China have restrictive effects for the imports from main exporters all over the world. Our research confirms some of the results reported elsewhere in the literature while differences remain in some aspects.First, in general trade control measures do have import restrictive effect in China. Second, tariff plays an important r ole even after China entry into the WTO. So far it’s still the most efficient policy tool. Third, TBT is the most frequently used NTM in China and cover almost all the imports. TBT do have some trade depressing effect but the effect is relatively small compared to the effect of tariff. Fourth, in contrast to the general belief that TBT works as a substitute to tariff and traditional NTM in developed countries（Thonsbury1998, Abbott 1997 etc）, there is no obvious substitution effect between tariff and TBT in China, moreover, the TBT is complementary to tariff in some extent.定量商业作用技术贸易壁垒：证据从中国1. 介绍技术贸易壁垒TBT现在普遍并且增加了对国际贸易的冲击。

模型预测油田水中溶解的碳酸钙含量：压力和温度的影响XXX 译摘要：油田中水垢沉积会对储层造成伤害、堵塞地层孔道、表面以及注入设备。

碳酸钙是水中最常见的结垢化合物之一，储层产生的盐水会使压力和温度降低，储层压力降低会使CaCO3的溶解度降低，进而提高体系中碳酸钙的饱和速率，而温度下降会产生相反的结果。

因此温度和压力一起作用的结果可能增加或减小CaCO3溶解度，用体系温度的变化来指定其压力的变化。

因此，在石油生产系统中精确的预测方法的应用备受关注。

目前的研究重点是运用基于最小二乘支持向量机(LSSVM)预测模型来估计油田水中溶解碳酸钙浓度的大小。

用超优化参数（r和C2）的遗传算法（GA）嵌入到LSSVM模型，这种方法可简单准确的预测油田卤水中溶解碳酸钙浓度的最小量。

1.引言随着油田卤水压力和温度变化，气体可能会从储层到地表的运动，导致某些固体沉淀。

为了保持注水井压力平衡并将油运移到生产井，有时需要将卤水注入到储层中，因此，过量的盐垢可以沉积在储层或井眼内。

对于大部分油田结垢多会发生在此过程中。

碳酸钙沉积通常是一个自发的过程，沉积形成的主要原因是二氧化碳从水相逸出，导致油气层的压力下降，该过程会除去了水中的碳酸，直到方解石溶解完全。

在恒定二氧化碳分压下，方解石的溶解性随温度的降低而降低[1-4]。

根据公式（1），碳酸钙沉积垢来自碳酸钙沉淀：Ca2+ + CO32-→ CaCO3↓下面的公式为碳酸的电离式[5–7]：CO2 + H2O → H2CO3H2CO3→ H+ + HCO3-HCO3-→ H+ + CO32-若要形成碳酸氢根离子和氢离子，碳酸要电离，因为碳酸的第一电离常数远大于它的第二电离常数，从碳酸第一电离离子化的氢离子与水中自由的碳酸根离子结合。

此外，碳酸钙沉淀的方程式可以说明[8–10]：Ca(HCO3)2→CaCO3↓+ CO2↑+ H2O碳酸钙的溶解度很大程度上取决于二氧化碳在水中的含量（即二氧化碳气体逸出时所需最小的分压）[10–12]。

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.。

无线网络的入侵探测和监视1.导言无线计算机网络在世界各地正在成指数性地增加。

无论是无执照的无线电频率（RF）频谱协会和有执照的频谱协会都使用它们。

在现有的无线计算机网络中无线网络操作目前是在无执照协会中最流行的。

ieee 802.11协议的开放性和“自由”射频协会的有效性促使许多公司的制造商和共同生产现成现货（COTS）的电脑网络设备公司进入无线领域的竞争。

这些公司之间的竞争已降低802.11无线网络设备的价格，推动和改善了用户对这些设备的经验。

最终的结果是企业和消费者对于设备采用率的增加，wifi联盟的建立，和联盟“wi-fi”的广泛使用，“wi-fi”被用来描述这些网络。

消费者在家里使用802.11设备，在现有的建设中减少线路运行的负担，促进和室友或邻居宽频互联网服务的共享，并提高它们的“连通范围。

”私营企业和政府机构（各级）正在部署无线网络以减少布线成本，提高员工的流动性，让待业人员上网，在他们现有的商业模式（咖啡馆，机场，酒店等）中创建一个附加的收入来源。

各市（费城，旧金山，大湾，MI）正在部署无线网络，让缺乏这种功能的地方能够实现宽带互联网接入;为贫困社区提供有限的高速宽带接入; 在诸如船坞和国家公园等地方提供宽带，这是由传统的宽带提供商所通过的; 并通过紧急响应站和其他城市机构为他们自己提供更高质量,更完善的网络覆盖来使用。

总之，这些Wi - Fi网络部署无处不在。

许多思想已经并正在投入有线和无线网络的评估成本效益分析，例如如何有效地覆盖写字楼，直辖市，如何有效地管理大型网络的无线接入点，以及如何用802.11技术取代互联网服务提供商来节省金钱。

相比之下，在无线安全和出于安全方面的检测投入了很少的人力和财力。

一些公司如AirMagnet和AirDefense已经建立了推销自己无线安全软件和硬件的体系。

但是，他们出售的产品重点在于办公室环境，网络优化和性能测试，比起较新的无线攻击，更重视现有的攻击。

IntroductionIn recent decades, economists have begun to identify technical progress, or more generally, knowledge creation, as the major determinant of economic growth. Until the 1970s, the analysis of economic growth was typically based on neoclassical models that explain growth with the accumulation of labor, capital, and other production factors with diminishing returns to scale. In these models, the economy converges to steady state equilibrium where the level of per capita income is determined by savings and investment, depreciation, and population growth, but where there is no permanent income growth. Any observed income growth per capita occurs because the economy is still converging towards its steady state, or because it is in transition from one steady state to another.The policies needed to achieve growth and development in the framework of these models is therefore straightforward: increases in savings and investments and reductions in the population growth rate, shift the economy to a higher steady state income level. From the view of developing countries, however, these policies are difficult to implement. Low income and development levels are not only consequences, but also causes of low savings and high population growth rates. The importance of technical progress was also recognized in the neoclassical growth models, but the determinants of the level of technology were not discussed in detail; instead, technology was seen as an exogenous factor. Yet, it was clear that convergence in income percapita levels could not occur unless technologies converged as well.From the 1980s and onwards, growth research has therefore increasingly focused on understanding and ontogenetic technical progress. Modern growth theory is largely built on models with constant or increasing returns to reproducible factors as a result of the accumulation of knowledge. Knowledge is, to some extent, a public good, and R&D, education, training, and other investments in knowledge creation may generate externalities that prevent diminishing returns to scale for labor and physical capital. Taking this into account, the economy may experience positive long-run growth instead of the neoclassical steady state where per capita incomes remain unchanged. Depending on the economic starting point, technical progress and growth can be based on creation of entirely new knowledge, or adaptation and transfer of existing foreign technology.Along with international trade, the most important vehicle for international technology transfer is foreign direct investment (FDI). It is well known that multinational corporations (MNCs) undertake a major part of the world’s private R&D efforts and production, own and control most of the world’s advanced technology. When a MNC sets up a forei gn affiliate, the affiliate receives some amount of the proprietary technology that constitutes the parent’s firm specific advantage and allows it to compete successfully with local firms that have superior knowledge of local markets, consumer preferences, and business practices. This leads to a geographical diffusion of technology, but not necessarily to any formal transfer of technology beyond the boundaries of the MNCs; the establishment of a foreign affiliate is, almost per definition, a decision to internalize the use of core technology.However, MNC technology may still leak to the surrounding economy through external effects or spillovers that raise the level of human capital in the host country and createproductivity increases in local firms. In many cases, the effects operate through forward and backward linkages, as MNCs provide training and technical assistance to their local suppliers, subcontractors, and customers. The labor market is another important channel for spillovers, as almost all MNCs train operatives and managers who may subsequently take employment in local firms or establish entirely new companies.It is therefore not surprising that attitudes towards inward FDI have changed considerably over the last couple of decades, as most countries have liberalized their policies to attract all kinds of foreign investment. Numerous governments have even introduced various forms of investment incentives to encourage foreign MNCs to invest in their jurisdiction. However, productivity and technology spillovers are not automatic consequences of FDI. Instead, FDI and human capital interact in a complex manner, where FDI inflows create a potential for spillovers of knowledge to the local labor force, at the same time as the host country’s level of human capital determines how much FDI it can attract and whether local firms are able to absorb the potential spillover benefits.2. Foreign Direct Investment and SpilloversThe earliest discussions of spillovers in the literature on foreign direct investment date back to the 1960s. The first author who systematically introduced spillovers (or external effects) among the possible consequences of FDI was MacDougall (1960), who analyzed the general welfare effects of foreign investment. The common aim of the studies was to identify the various costs and benefits of FDI.Productivity externalities were discussed together with several other indirect effects that influence the welfare assessment, such as those arising from the impact of FDI on government revenue, tax policies, terms of trade, and the balance of payments. The fact that spillovers included in the discussion was generally motivated by empirical evidence from case studies rather than by comprehensive theoretical arguments.Yet, the early analyses made clear that multinationals may improve locatives efficiency by entering into industries with high entry barriers and reducing monopolistic distortions, and induce higher technical efficiency if the increased competitive pressure or some demonstration effect spurs local firms to more efficient use of existing resources. They also proposed that the presence may lead to increases in the rate of technology transfer and diffusion. More specifically, case studies showed that foreign MNCs may:(1) Contribute to efficiency by breaking supply bottlenecks (but that the effect may become less important as the technology of the host country advances);(2) Introduce new know-how by demonstrating new technologies and training workers who later take employment in local firms;(3) Either break down monopolies and stimulate competition and efficiency or create a more monopolistic industry structure, depending on the strength and responses of the local firms;(4) Transfer techniques for inventory and quality control and standardization to their local suppliers and distribution channels;Although this diverse list gives some clues about the broad range of various spillover effects, it says little about how common or how important they are in general. Similar complaints can be made about the evidence on spillovers gauged from the numerous case studies discussing various aspects of FDI in different countries and industries. These studies often contain valuable circumstantial evidence of spillovers, but often fail to show how significant the spillover effectsare and whether the results can be generalized.For instance, many analyses of the linkages between MNCs and their local suppliers and subcontractors have documented learning and technology transfers that may make up a basis for productivity spillovers or market access spillovers. However, these studies seldom reveal whether the MNCs are able to extract all the benefits that the new technologies or information generate among their supplier firms. Hence, there is no clear proof of spillovers, but it is reasonable to assume that spillovers are positively related to the extent of linkages.Similarly, there are many works on the relation between MNCs entry and presence and market structure in host countries, and this is closely related to the possible effects of FDI on competition in the local markets. There are also case studies of demonstration effects, technology diffusion, and labor training in foreign MNCs. However, although these studies provide much detailed information about the various channels for spillovers, they say little about the overall significance of such spillovers.The statistical studies of spillovers, by contrast, may reveal the overall impact of foreign presence on the productivity of local firms, but they are generally not able to say much about how the effects come about. These studies typically estimate production functions for locally owned firms, and include the foreign share of the industry as one of the explanatory variables. They then test whether foreign presence has a significant positive impact on local productivity once other firm and industry characteristics have been accounted.Research conclude that domestic firms exhibited higher productivity in sectors with a larger foreign share, but argue that it may be wrong to conclude that spillovers have taken place if MNC affiliates systematically locate in the more productive sectors. In addition, they are also able to perform some more detailed tests of regional differences in spillovers. Examining the geographical dispersion of foreign investment, they suggest that the positive impact of FDI accrue mainly to the domestic firms located close to the MNC affiliates. However, effects seem to vary between industries.The results on the presence of spillovers seem to be mixed; recent studies suggest that there should be a systematic pattern where various host industry and host country characteristics influence the incidence of spillovers. For instance, the foreign affiliate’s levels of tech nology or technology imports seem to influence the amount of spillovers to local firms. The technology imports of MNC affiliates, in turn, have been shown to vary systematically with host country characteristics. These imports seem larger in countries and industries where the educational level of the local labor force is higher, where local competition is tougher, and where the host country imposes fewer formal requirements on the affiliates’ operations.Some recent studies have also addressed the apparent contradictions between the earlier statistical spillover studies, with the hypothesis that the host country’s level of technical development or human capital may matter as a starting point.In fact, in some cases, large foreign presence may even be a sign of a weak local industry, where local firms have not been able to absorb any productivity spillovers at all and have therefore been forced to yield market shares to the foreign MNCs.3. FDI Spillover and Human Capital DevelopmentThe transfer of technology from MNC parents to its affiliates and other host country firms is not only mbodied in machinery, equipment, patent rights, and expatriate managers and technicians,but is also realized rough the training of local employees. This training affects most levels of employees, from simple manufacturing operatives through supervisors to technically advanced professionals and top-level managers. While most recipients of training are employed in the MNCs own affiliates, the beneficiaries also include employees among the MNCs suppliers, subcontractors, and customers.Types of training ranged from on-the-job training to seminars and more formal schooling to overseas education, perhaps at the parent company, depending on the skills needed. The various skills gained through the elation with the foreign MNCs may spill over directly when the MNCs do not charge the full value of the training provided to local firms or over time, as the employees move to other firms or set up their own businesses.While the role of MNCs in primary and secondary education is marginal, there is increasingly clear evidence hat FDI may have a noticeable impact on tertiary education in their host countries. The most important effect is perhaps on the demand side. MNCs provide attractive employment opportunities to highly skilled graduates in natural sciences, engineering, and business sciences, which may be an incentive for gifted students to complete tertiary training, and MNCs demand skilled labor, which may encourage governments to invest in higher education.Many studies undertaken in developing countries have emphasized the spillovers of management skills. There is evidence of training and capacity development in technical areas, although the number of detailed studies appears smaller.While training activities in manufacturing often aim to facilitate the introduction of new technologies that are embodied in machinery and equipments, the training in service sectors is more directly focused on strengthening skills and know-how embodied in employees. This means that training and human capital development are often more important in service industries. Furthermore, many services are not tradable across international borders, which mean that service MNCs to a great extent are forced to reproduce home country technologies in their foreign affiliates. As a consequence, service companies are often forced to invest more in training, and the gap between affiliate and parent company wages tends, therefore, to be smaller than that in manufacturing.4. ConclusionThis paper has noted that the interaction of FDI and spillovers is complex and highly non-linear, and that several different outcomes are possible. FDI inflows create a potential for spillovers of knowledge to the local labor force, at the same time as the host country’s level of human capital determines how much FDI it can attract and whether local firms are able to absorb the potential spillover benefits. Hence, it is possible that host economies with relatively high levels of human capital may be able to attract large amounts of technology intensive foreign MNCs that contribute significantly to the further development of labor skills. At the same time, economies with weaker initial conditions are likely to experience smaller inflows of FDI, and those foreign firms that enter are likely to use simpler technologies that contribute only marginally to local learning and skill development.翻译一：外商直接投资溢出效应研究1.引言在最近几十年中，经济学家们已开始确定技术进步，或更普遍认为知识创造，作为经济增长原动力的一个重要决定因素，直到20世纪70年代，分析经济增长运用典型的新古典主义模型来解释经济增长的积累，劳动力、资本等生产要素与收益递减的规模。
