法律法学论文夫妻忠实义务研究中英文资料对照外文翻译文献外文参考文献摘录:A Study on responsibility o f conjugal chastityKerry MutchW alton Centre NHS Foundation Trust,Fazakerley,Liverpool,United Kingdom.Marriage is unification in wedlock concerning both party’s right and responsi bility voluntarily arranged by men and women for the purpose of living t ogether permanently.In order to live t ogether happily and satisfactorily,mutually supporting is needed t o guarantee the affluence of physical life and mutual chastity to support the felicitousness of the spiritual life.Therefore,mutual chastity is a major factor to support the wedlock,which is also a focus of marriage law.During the revision of marriage law in2001,the debate over the responsibility of mutual chastity was the mos t appealing issue.After intense arguing,finally the article“the spouses shall maintain mutual chastity”was listed in the revised marriage law. However the ar gument over mutual chastity of the spouses has never stopped,mo r e issues concerning it are still needed to be further studied.The thesis tries t o investigate and review the mutual responsibility of conjugal chastity systematically.In order to study the subject systematically,the historical,sociological,comparative law,empirical,dynamic and static analysis appr o aches by which the historical development of conjugal chastity、jurisprudential analysis of it and present regulation on it are observed and reviewed,are employed in the research.The thesis consists of four chapters.ChapterⅠ,which is composed of three subchapters,observes the mutual responsibility of conjugal chastity from the perspective of its historical development.In SubchapterⅠexplains the exact connotation of chastity andascertains the definite meaning of responsibility of conjugal chastity further.The basic meaning of chastity is loyal to each other,which connotes that the hus b and and wife shouldbe faithful t o one another n o t only in their acts bu t also in mental communication as well.Keywords:marriage responsibility o f conjugal chastity spouse spouse’s right divorceHowever,the mental communication is no t the regulating target of law,thus the conjugal chastity only d e no t es mutual loyalty in their sexual life and denies extramarital sex from the angle of marriage law.In SubchapterⅡ,the author observes and studies the awareness and responsibility of conjugal chastity under the primitive、slavery、feudal and the contemporary society irrespectively.After that the author has commented on the changes of attitudes towards the conjugal chastity in the Chinese marital legislation.During the investigation into the conjugal chastity in the pr olonged history,the author found that the regulation on responsibility of the conjugal chastity was implied by two major line,that is,the evolution from inequality bet w een men and women to the equality betw een the both;and the regulation on it thr ough statutory r emedy by private right instead of the interference by public power.Simultaneously,the linkage betw een the development,evolution of mutual responsibility of conjugal chastity and those of human marriage life and the changes of the viewpoints on conjugal relations,sexual morality and sex awareness are deeply connected.In SubchapterⅢ,the author mainly observes the influence of the changes of conjugal love,attitudes towards family and sex upon the viewpoint over conjugal chastity in contemporary China.As the wheels of history rolls on,the human’s viewpoint over the sexual morality and sex awareness has been changing all the time.As the inflation of individualism and liberalism in mos t capitalist countries,the previous exclusive love attitudes has been replaced by the non-interference of mutual freedom.At the s a me time the viewpoints of the judicial circle and judicature have c han ge d mo r e or less by the contemporary thought, therefore the strict rule has been loosened.According t o the previous research,the author claims that when we restructures the mutual responsibility of conjugal chastity in marriage legislation in our country,the changes of contemporary conjugal love,attitudes towards family and sex should be investigated and taken into account.In the following part the author has looked into the changes in present China in detail,and some personal opinions t o themare also released.On the basis of the study above,t he author holds that the responsibility of conjugal chastity is closely related with conjugal relationship,in regar d t o the influence of awareness of conjugal love、family and sex upon the responsibility of conjugal chastity,two aspects should be considered,that is,on the one hand,the changes should no t be ignored,in the design of responsibility of conjugal chastity,the old r oute to recover the adultery law and punish the adulterers had been discarded by the Age,and public power exploited in the punishment of extramarital sex should be cautious;On the other hand,the changes of viewpoints to marriage and family upon the conjugal love have never undermined the stable cornerstone of family structure in the Chinese society that is because the values of marital morality under the back gr ound of Confucian culture have always been supporting the Chinese marriage firmly.Some social surveys show that the sex concerning extramarital sex, especially that has gravely undermined the stability of families,the attitudes of our people are clear,i.e.,they oppose the extramarital sex.In the western countries,whereas,after the disastrous experiment of“sex revolution”,the slogans of“returning family”and“faithfu lness is fundamental to conjugal love”are back to be reused.Thus writing the responsibility of conjugal chastity into law can be considered the pr omotion of faithfulness in conjugal love, that is the inner voices of the people at home and abroad.China should g et integrated into the world trend,learn from the lessons of foreign countries and no t recover the old way of “serious results getting from excessive freedom of sex”in the West,thus our marriage law can be made as a new symbol of our socialist marriage and family.ChapterⅡ,consisting of three subchapters,is the jurisprudential analysis over responsibility of conjugal chastity.At the beginning of SubchapterⅠ,the author holds that the responsibility of conjugal chastity is the essence of marriage.The responsibility of conjugal chastity is the natural demand of marriage,which is also an e mbo dime n t of the exclusivity of conjugal sex and the demand of social nature of marriage.In our socialist society,monogamy is the requisite demand of the responsibility of conjugal chastity,which is a vigorous safeguard of monogamy as well.Then, the author analyses the juristic value of the entry of responsibility of conjugal chastity into law,the major reason of which is that the responsibility of conjugal chastity is alwaysconsidered as a good virtue.The safeguard of responsibility of conjugal chastity,in essence,could be r egar ded as the protection and pr omotion of justice by nation.The responsibility of conjugal chastity embodies the humanistic solicitude of law.The humanistic solicitude towards responsibility of conjugal chastity is such a proposition essentially,that is,the regulation and bound of the marital life of people by law is t o lead them t o live a safe、happy and satisfactory marital life, which can connect the individuality of man with the social nature of man intrinsically; Therefore,certain harmonies from the equilibrium of interests betw een individuals and society may be reached,and the value of man can be elevated.SubchapterⅡmainly observes and reviews the juristic identification of the natur e of responsibility of conjugal chastity.At first,the author holds that the responsibility of conjugal chastity is a derivative right of spouse’s right,which is a basic right of dignity betwee n the hus b an d and wife formulated by law.The maintenance of wedlock is b as e d on two elementary conditions,that is,the responsibility of cohabitation and being loyal t o each other.Therefore the responsibility of conjugal chastity,a derivative right fro m the spouse’s right,becomes the core of spouse’s right.And the characteristics of the responsibility of conjugal chastity are generalized in detail thereinafter.In the following part of this subchapter,the author concludes that the responsibility of conjugal chastity inevitably has the nature of right of personality.Though the responsibility of conjugal chastity has dual natures of right of personality and right of dignity,they should be distinguished.Right of dignity is the basic natur e of the responsibility of conjugal chastity,whereas, right of personality is the attaching nature of the responsibility of conjugal chastity.In SubchapterⅢ,the author makes a comparative law research on the responsibility of conjugal chastity and the other related rights.Firstly,the author analyzed the relationship betw een the responsibility of conjugal chastity and the right of sexual fr eedom from different perspectives. And then the relationship betw een the responsibility of conjugal chastity and privacy is being observed and analyzed.In chapterⅢ,the author mak es a reflection on the responsibility of conjugal chastity in reality and some suggestions are also br ought up for the future legislation on this subject.After further study the author holds that the responsibility of conjugal chastitymay be regulated by morality,b u t the regulation by law should no t excluded,and the private natur e of conjugal relation should be taken into account simultaneously.After that,the judicial regulation on the responsibility of conjugal chastity is analyzed. At the final part,the author brings up some suggestions on the legislation of the responsibility of conjugal chastity in the future,that is,(1)the setting up of the definition of spouse’s right;(2)taking adultery as a statutory reason for divorce;(3)in the compensation for damages arisen from divorce,adultery should be considered as a statutory reason in the lawsuit of compensation for damages in divorce and change the“no-fault party”term into“victim”. Furthermore,the compensation for damages shall be n ot only applied to divorce by lawsuit bu t also to registry divorce and the scale of compensation for damages should include property and spiritual damages.ChapterⅣis a prospect of the future research on the responsibility of conjugal chastity.Though the thesis is a tentative study on the responsibility of conjugal chastity,the target of it is clear,i.e.,all the efforts made in this thesis is trying to perfect the marital legislation and a spur t o induce mo r e better ideas br ought up by academia.外文参考文献译文:夫妻忠实义务研究克里马奇沃尔顿中心琥珀酰亚胺信托基金会,扎克雷,利物浦,英国婚姻是男女双方以永久共同生活为目的,依法自愿缔结的具有权利义务内容的结合。
英语多喝水的作文Title: The Importance of Hydration: Drink More Water。
In our fast-paced lives, amidst the hustle and bustle, one thing that often gets overlooked is the simple act of staying hydrated. Yet, this seemingly small action plays a monumental role in our overall well-being. Let's delve into why drinking more water is crucial for our health and vitality.First and foremost, water is the essence of life. Our bodies are composed of about 60% water, and every system depends on it to function properly. From regulating body temperature to aiding digestion and nutrient absorption, water is involved in virtually every bodily function. When we don't drink enough water, we risk dehydration, which can lead to a myriad of health issues, including fatigue, headaches, and even more severe complications.Moreover, staying hydrated is essential for cognitivefunction. Research has shown that even mild dehydration can impair cognitive performance, affecting our mood, concentration, and overall mental clarity. So, if you find yourself feeling sluggish or struggling to focus, it might be time to reach for that glass of water.Furthermore, hydration is vital for maintaining physical performance and endurance, whether you're an athlete or simply enjoy staying active. When we exercise, we lose water through sweat, which needs to be replenished to prevent dehydration and optimize performance. Proper hydration ensures that our muscles and joints stay lubricated, reducing the risk of cramps and injuries during physical activity.Beyond the immediate benefits, drinking more water also supports long-term health. Adequate hydration is linked to a lower risk of chronic diseases, such as heart disease, kidney stones, and urinary tract infections. By keeping our bodies well-hydrated, we can help prevent these conditions and promote overall longevity.But how much water should we actually be drinking? While the "eight glasses a day" rule is a good starting point, individual hydration needs vary based on factors such as age, weight, activity level, and climate. A better approach is to listen to your body's signals. Thirst is a clear indicator that your body needs more water, so don't ignore it. Additionally, paying attention to the color of your urine can provide insights into your hydration status. Pale yellow urine is a sign of adequate hydration, while dark yellow or amber urine may indicate dehydration.Incorporating more water into your daily routinedoesn't have to be a daunting task. Start by carrying a reusable water bottle with you wherever you go, making it easier to sip throughout the day. Set reminders on your phone or computer to prompt you to take water breaks regularly. Experiment with infusing your water with fruits or herbs for added flavor, making hydration more enjoyable. And remember, other beverages like herbal tea and coconut water can also contribute to your daily fluid intake.In conclusion, the benefits of drinking more water areundeniable. From supporting physical and mental performance to safeguarding long-term health, staying hydrated is essential for thriving in all aspects of life. So, let's raise a glass to hydration and make it a priority to keep our bodies happy, healthy, and hydrated. Cheers to a well-watered life!。

托福阅读完全没必要逐字分析托福阅读完全没必要逐字分析。
时间很重要,在托福阅读中就更加重要。
所以不需要逐字逐句的将托福阅读弄懂,很多时候,即使遇到陌生的词,根据上下文甚至自己的一些常识,也不会影响对文章的理解。
一起来看看下文吧!托福阅读完全没必要逐字分析科学的托福考试方法关于阅读方法本文只是对在有限时间内有效阅读托福文章的方法进行一个简单的介绍。
阅读技巧,特别是速度技巧中,有两个重要的方法:Skimming&Scanning.Skimming是只看主要大意的速读。
一篇文章的大意是有重点的。
比如,当出现first second的这种归类总结的地方,或because,as a result这样的因果关系,或是 but,however的语意转折处,都需要格外留心。
托福文章讲述主要观点之后通常会有for example来佐证,如果看懂了主要观点,那么对示例所用的时间和精力就不需要太多了。
Skimming的技巧在第一遍阅读文章意图抓住文章大意时是非常重要的。
Scanning是“扫描”,但具体到阅读中,大家最熟悉的莫过于查词典时。
在有意识地去查某个生词的时候,我们不会去把它所在的页上每一个字都看一遍才找到想要的。
几乎眼睛对词典中的一页扫一下,脑中只有要找的字,看到它,其他的地方都像没有看到一样。
在托福的阅读中,scanning的技巧在回答问题时,根据题干中问到的内容,在文章中scan,可以帮助考生准确地定位,找到答案。
以上两种是在托福阅读中最常用也是最有效的技巧。
托福的文章长度大多在300-400字之间。
以平均每篇读10分钟计算,按照每分钟阅读150字的速度,一篇文章从头到尾通读,至少需2-3分钟。
这可了解文章的大意,但不一定保证读得透彻。
在第一遍通读的过程中,考生不要期望每个字都一定要理解,遇到不懂的字不必多逗留或苦思冥想可能的意思,这样会浪费时间的。
只需一直往下看,用前面介绍到的skimming原则,掌握文章的主旨即可。
水油分离实验英语作文Title: Experiment on Oil-Water Separation。
Oil-water separation is a crucial process in various industries, including environmental protection, wastewater treatment, and oil refining. In this experiment, we aimed to understand the principles behind oil-water separation and explore different methods to achieve efficient separation. 。
Firstly, we set up a simple experiment using a mixture of oil and water in a transparent container. The oil and water were mixed thoroughly to form an emulsion. We observed the emulsion under different conditions to analyze the factors affecting the separation process.To facilitate the separation, we introduced several methods:1. Gravity Separation: This method relies on thedensity difference between oil and water. We allowed the mixture to stand undisturbed for a period of time, during which the oil floated to the top due to its lower density, while the water settled at the bottom. This process, known as sedimentation, demonstrated the basic principle of gravity separation.2. Centrifugation: In this method, we used a centrifuge to accelerate the separation process. By spinning the mixture at high speeds, centrifugal force acted on the components, causing the denser water to move towards the outer edge while the lighter oil remained in the center. Centrifugation proved to be a rapid and effective technique for separating oil and water.3. Coalescence: We also explored the use of coalescing agents to enhance the coalescence of oil droplets, promoting their aggregation and facilitating separation. By adding a coalescing agent to the emulsion, we observed the formation of larger oil droplets, which facilitated their removal from the water phase.4. Filtration: Filtration involves passing the emulsion through a filter medium to separate the oil and water phases. We used a filter paper with fine pores to trap the oil while allowing the water to pass through. This method proved useful for removing small oil droplets from the emulsion.Throughout the experiment, we monitored the separation process and analyzed the efficiency of each method. We observed that factors such as temperature, agitation, and the concentration of contaminants influenced the effectiveness of oil-water separation techniques.In conclusion, oil-water separation is a complex process that can be achieved through various methods, including gravity separation, centrifugation, coalescence, and filtration. Understanding the principles behind these techniques is essential for addressing environmental challenges and ensuring efficient industrial processes.。

Experiment 1 PID regulating of water level of a single tank systemObjective1.This experiment helps students learn the structure of a single loop feedback system and itsworking principle.2.It also helps students study the step response of the system with P, PI or PID regulation.3.It helps students study the anti disturbance performance of the P, PI or PID regulated system.4.Students do qualitative analysis of influence of parameter variation on the system’sperformance if P, PI and PID regulators are used respectively.Equipment1.The process control equipment THKGK‐1 consisting of GK‐02, GK‐03, GK‐04, and GK‐07 .2.MultimeterputerTheoryIntroduction of the single tank water level control systemThe single tank water level control system is shown in Fig. 7‐1 and Fig. 7‐2. This is a single loop feedback control system whose objective is to keep the water level equaling to the required value while minimize the error caused by inner or exterior disturbance. Single loop control system is widely applied because of its simple structure, low cost, convenient operation and also because it satisfies many general processes.Figure 7‐1 The block diagram of the single tank water level control systemOnce the hardware of a single loop system is set up, the controlling quality depends substantially on the selection of the regulators’ parameters. Appropriate parameters could resultin satisfying controlling effect. Otherwise, if improper controlling parameters are employed, the regulating effect becomes bad or the system may even break down. Therefore tuning the regulator parameters is very important work after the system is set up.When the system is switched from manual operation to automatical operation it must not induce turbulence, which requires that the regulator output can follow the manual control andensure that no difference between measurement value and required value exits at the switching instant.Generally the system with a P regulator has static error. The value of proportional band affects the quantity of static error and also relates closely to the dynamic performance of the system. Because of the function of the integral, a PI regulator contributes zero static error to the system. Moreover, appropriate value of parameters and can also provide good dynamic performance. A PID regulator can not only eliminate the static error but also improve the dynamic performance. With the unit step input, the response of P , PI and PID regulating system are shown respectively as the three curves in Fig. 7‐3.Figure 7‐2 Sketch map of the water tank systemFigure 7‐3 Step response under P ,PI and PID regulating are shown as curve ①,②, and ③Experiment Content and Procedure1. Proportional (P) regulating① Connect the modules to form a single loop feedback system, referring to Fig. 7‐1. Theprocess is the top one of the three water tanks, and the controlled variable is the water level .② Start the devices and instruments, and tune the zero point and the gain of the sensor’soutput.③ Guided by the teacher, power on the control screen of the microprocessor, and start thecomputer supervising system.

Normally the water level is controlled to be at 50% of the tank height.⑤Observe the curve being shown on the computer screen, and wait for the curve to reachthe desired value, then switch the regulator to proportional regulating situation—the integral time constant is set to the maximum value and the integral and derivative switches rest at “off” position. After that, set the proportional band a middle value, push the “direct‐inverse” switch to “inverse” position, push the “manual” switch of the regulator to “automatical” position. Such that the system works in a closed loop condition.⑥Wait for a while for the water level to reach a stable state, then add a disturbance to theprocess ( usually a change of the reference input by positive or negative 10% magnitude is taken as a disturbance). The water level varies because of the disturbance. Observe the fluctuation of the water level caused by the disturbance till it become stable again.⑦Reduce the proportional band , repeat step 6, observe the transient curve on thescreen, and record the curve.⑧Increase the proportional band , repeat step 6, observe the transient curve on thescreen, and record the curve.⑨Select an appropriate value of so that a satisfying process curve could be obtained.Record this value of .⑩Pay attention that students must wait for the system to achieve a stable state every time they want to execute a new operation.2.Proportional and integral (PI) regulating①Based on the P regulating, an integral function is added in the regulator (the “integral”knob is tuned to a middle position and the “integral” switch is set at “on”). Observe whether or not the controlled variable (the water level) can reach the reference input, so that to verify that the PI regulating could remove the static error.②Set a middle value to the proportional band and keep it unchanged. Set integraltime constant T a large value, and give a step disturbance to the process and observe the curve of the output signal (water level). Set integral time constant a small value, and givea step disturbance to the process and observe the curve of the output signal (water level).Record the overshoots in both cases in table 1.Table 1 The overshoot referring to different values of and a constant value of Integral time constant Ti Large value Small valueOvershoot Mp③Set the integral time constant a middle value and keep it unchanged. Set a largevalue, and give a step disturbance to the process and observe the curve of the output signal (water level). Set a small value, and give a step disturbance to the process and observe the curve of the output signal (water level). Record the overshoots in both cases in table2.Table 2 The overshoot referring to different values of and a constant value of Proportional band Large value Small valueOvershoot Mp④Select appropriate value for and so that the system has a satisfying transientoutput signal’s curve when it is exposed to a step disturbance. This curve could be obtained by changing the reference input from 50% to 60% of full range.3.Proportional, integral and derivative (PID) regulating① Based on the preceding PI regulating, a derivative function is added in the regulator,that means the “D” switch is turned on. A disturbance with the same magnitude of that in preceding PI regulating is given to the process. Record the dynamic response curve of the controlled variable. Compare the curve with that one obtained in preceding PI regulating, and get a conclusion of influence of derivative control on system performance.②Select appropriate value of , and so that the step response of the system is asatisfying transient curve ( The step input can be implemented by changing the reference input from 50% to 60% of the full range).③Record all the transient curves by the software in the computer and analyze theperformance of different regulators.Attention①When the circuit is connected, it must be checked and approved by the teacher beforeit is powered on.②It must be supervised by the teacher when students start the computer and themicroprocessor screen.③If the parameters are not appropriate, the system may work improperly.Requirement for the report①Plot the block diagram of the single tank water level control system.②Practice switching from manual control to automatical control and describe the way tomake sure that the output variable does not change sharply at the moment of switching.③Record or draw the step response curves referring to different values at P regulatingmode.④Record or draw the step response curves referring to different values and constantat P regulating mode. Also record or draw the step response curves referring to different values and constant .⑤Draw the step response curves of PID regulating, and analyze the function of Dregulating.⑥Compare the static errors and dynamic performance of the system obtained at P, PI andPID regulating mode.Questions①How to reduce or eliminate static error? Is it possible for the proportional regulating toeliminate the static error?②Do qualitative analysis of the influence of parameters variation of , and onthe system performance.。
