英译汉佳作欣赏

英译汉：佳译赏析巧选主语成妙译（1）原文】饱经沧桑的20世纪仅剩下几个春秋，人类即将跨入充满希望的21世纪。

【译文】I n a few years’ time, mankind will bid farewell to the 20th c entury, a century full of vic issitudes, and enter into the 21s t c entury, a c entury full of hopes.【赏析】1995年，联合国举办纪念成立50周年庆祝活动，江主席出席并发表演说。

原文是该篇演说的第一句，是地道的汉语。

翻译此句时，一般译者往往会亦步亦趋地将原文译为两个分句，分别以“饱经沧桑的20世纪”和“人类”作主语。

但高明的译者吃透了原文的精神，选择mankind为主语统领全句，以准确而地道的英语译出，确实是一则难得的佳译，值得翻译爱好者认真体会。

英译汉：佳译赏析之“肚里的墨水”（2）【原文】T heir family had more money, more hors es, more slaves than any one els e in the Country, b ut the boys had less grammar than mos t of their poor C racker neighbors.【译文】他们家里的钱比人家多，马比人家多，奴隶比人家多，都要算全区第一，所缺少的只是他哥儿俩肚里的墨水，少得也是首屈一指的。

【赏析】原文选自Gone With the Wind。

译文忠实且流畅，算得上好译文，特别值得一提的是译者对grammar的处理，如果照搬字典自然难于翻译，但译者吃透了原句精神，译为“肚里的墨水”，真是再妥帖不过了。

英译汉：佳译赏析之“思前想后”（3）【原文】A nd in these meditations he fell asleep.【译文】他这么思前想后，就睡着了。

本科毕业论文外文翻译外文译文题目:不确定条件下生产线平衡：鲁棒优化模型和最优解解法学院：机械自动化专业：工业工程学号: 201003166045学生姓名: 宋倩指导教师：潘莉日期: 二○一四年五月Assembly line balancing under uncertainty: Robust optimization modelsand exact solution methodÖncü Hazır , Alexandre DolguiComputers ＆Industrial Engineering，2013,65：261–267不确定条件下生产线平衡：鲁棒优化模型和最优解解法安库·汉泽，亚历山大·多桂计算机与工业工程，2013，65：261–267摘要这项研究涉及在不确定条件下的生产线平衡，并提出两个鲁棒优化模型。

假设了不确定性区间运行的时间。

该方法提出了生成线设计方法,使其免受混乱的破坏。

基于分解的算法开发出来并与增强策略结合起来解决大规模优化实例.该算法的效率已被测试,实验结果也已经发表。

本文的理论贡献在于文中提出的模型和基于分解的精确算法的开发.另外，基于我们的算法设计出的基于不确定性整合的生产线的产出率会更高，因此也更具有实际意义。

此外,这是一个在装配线平衡问题上的开创性工作,并应该作为一个决策支持系统的基础。

关键字：装配线平衡；不确定性; 鲁棒优化；组合优化；精确算法1.简介装配线就是包括一系列在车间中进行连续操作的生产系统。

零部件依次向下移动直到完工。

它们通常被使用在高效地生产大量地标准件的工业行业之中。

在这方面，建模和解决生产线平衡问题也鉴于工业对于效率的追求变得日益重要。

生产线平衡处理的是分配作业到工作站来优化一些预定义的目标函数。

那些定义操作顺序的优先关系都是要被考虑的,同时也要对能力或基于成本的目标函数进行优化。

就生产（绍尔，1999）产品型号的数量来说，装配线可分为三类：单一模型（SALBP）,混合模型(MALBP）和多模式（MMALBP）。

南邮外文翻译一范例

南京邮电大学毕业设计(论文)外文资料翻译学院(系)：经济与管理学院专业：学生姓名：班级学号：外文出处：Journal of Occupational Psychology,1977, Vol.50附件：1.外文资料翻译译文；2.外文原文附件：1.外文资料翻译译文重新评估工作满意度和工作生活质量——詹姆斯.C.泰勒有用的工作满意度的措施在评估工作的特点以及改善工作生活质量中是有问题的。

根据民意调查和组织调查显示，多年以来，虽然在高和稳定的工作满意度水平下，雇员的挫折感和异化迹象却一直在增加。

经过更密切的检查，这似是而非的调查导致的结论是：无论再严谨的工作满意度调查及测量，得到的只是修改工作和减少员工的挫折感方面的没必要的信息。

根据以往的经验以及对工作生活质量的研究表明，为了克服这个缺陷，在测量工作满意度的时候，雇员本身需要更多地参与测量。

工作满意度已经成为一个模糊不清的尴尬概念。

许多代表着工业人文主义利益的社会科学调查员都对工作满意度十分有兴趣，他们建议要去关注和改善人与职位的关系，提高工作满意度。

从20世纪30年代开始，这种关注已经从制造业扩展到服务和文职部门。

然而，我们可以断言，大部分对工作满意度的研究都无法仅通过对工作及工作本身的研究。

历史上曾经有过对工作满意度的研究，这或许可以支持或者攻击现状，这种趋势还将继续下去。

尴尬的是，在对美国雇员的工作满意度的继续调查研究中，用极高的百分比来衡量他们工作的满意程度，而在同一时间内降低对工人的承诺，雇员所表达的通过增加缺勤率（特别是部分周缺勤），罢工（因其他原因除了工资）而拒绝谈判达成的合同以及破坏产品的比率显然变得更大。

雇员异化的这些问题已经提起公众的注意，但是如果公众关注继续增长，为什么雇员安静的绝望与工作越来越被看作是与压力之间的和解，这些事实和精心准备将使对工作满意度的严格调查成为必然。

前言本文的目的是在不减少抽样误差和防范反应的情况下，使用更精密的统计测试，在不同的模式下对满意度数据进行界定和衡量。

外文音译命名法的例子

音译法音译法就是模仿外文商标的发音而进行汉译的方法。

这种方法应用非常普遍，其特点是翻译快捷、简便，并能保留原名的音韵之美，让人体验到正宗的异国情调，同时也满足部分消费者追崇“洋味”的心理。

他们往往认为这种商标更能体现自己的身份和地位。

通常是若原语商标构不成意义,或属新奇型或专有独用型,多采用音译法。

如大家熟知的一些品牌：Motorola摩托罗拉，Nokia诺基亚，Sony索尼等代表的系列产品;Ford福特，Audi奥迪，BUICK别克，LINCOLN 林肯等轿车;adidas阿迪达斯，CHANEL夏奈尔，Pierre Cardin皮尔卡丹等服装;ROLEX劳利士，OMEGA欧米茄等手表;BOSS波士，ELIXIR 怡丽丝尔，BVLGARI宝格丽，LANC?ME兰蔻等化妆品;Levi's李维斯(牛仔服);ALIDA阿俪达(高级女鞋);Finbid芬必得(药品);Corona科罗娜，(啤酒);MacLaren麦克拉伦(婴儿车);Cartier卡地亚(珠宝手饰)等。

直译法直译法就是根据外文商标的语言，直接把词意翻译成汉语的方法。

译文的目的语与原文的始发语表达的形式和内容往往相同。

这也是一种应用广泛的方法，其特点是“不失真”，能保留原名传递的意义、信息、情感等，直接传达原文的语义，让消费者更能体会到原商标的涵义，甚至引发联想而产生兴趣、好感，利于商品的销售。

一般说来，如果商标原名本身具有某种特定的涵义或某种象征意义，就应尽可能地考虑直译。

如英国汽车Lotus，直译为“莲花”，能给人以许多美好的联想：莲“出淤泥而不染，濯清莲而不妖”的高洁、质朴，莲“香远益清”的芳香，“亭亭的风姿”，“姣姣的风韵”，“清水出芙蓉，天然去雕饰”不施粉黛的天生丽质，无与伦比的脱俗气质等等;床上用品Fair Lady译为“贵妇人”，给人一种高雅的感觉;轿车Crown译为“皇冠”，暗示轿车的显贵，若音译为“克朗”，感觉就相差甚远。

外文翻译--信号放大器-精品

At the most basic level, a signal amplifier does exactly what you expect –it makes a signal bigger! However, the way in which it is done vary with the design of the actual amplifier, the type of signal, and the reason why we want to enlarge the signal. We can illustrate this by considering the common example of a ―Hi-Fi‖ audio system.In a typical modern Hi-Fi: system, the signals will come from a unit like a CD player, FM tuner, or a Tape/Minidisk unit. The signals they produce have typical levels of the order of 100 mV or so when the music is moderately loud. This is a reasonably large voltage, easy to detect with something like an oscilloscope or a voltmeter. However, the actual power levels of these signals are quite modest. Typically, these sources can only provide currents of a few milliamps, which by P=VI means powers of just a few milliwatts. A typical loudspeaker will require between a few Watts and perhaps over 100 Watts to produce loud sound. Hence we will require some from of Power Amplifier to ―boost‖ the signal power level from the source and make it big enough to play the music.Many practical amplifier chain together a series of analog amplifier stages to obtain a high overall voltage gain. For example, a PA system might start with voltages of the order of 0.1 mV from microphones, and boost this to perhaps 10 to 100V to drive loudspeakers. This requires an overall voltage gain of10, so a number of voltage gain stages will be required.In many cases we wish to amplify the current signal level as well as the voltage. The example we can consider here is the signal required to drive the loudspeakers in a ―Hi-Fi‖ system. These will tend to have a typical input impedance of the order of 8 Ohms. So to drive, say, 100 Watts into such a loudspeaker load we have to simultaneously provide a voltage of 28 Vrms and 3.5 Arms. Taking the example of a microphone as an initial source again a typical source impedance will be around 100 Ohms. Hence the microphone will provide just 1 nA when producing 0.1 mV. This means that to take this and drive 100 W into a loudspeaker the amplifier system must amplify the signal current by a factor of over 10 at the same time as boosting the voltage by a similar amount. This means that the overall power gain required is 10 –i.e. 180 dB!This high overall power gain is one reason it is common to spread the amplifying function into separately boxed pre—and power—amplifiers. The signal levels inside power amplifiers are so much larger than these weak inputs that even the slightest ―leakage‖from the output back to the input may cause problems. By putting the high—power (high current) and low power sections in different boxes we can help protect the input signals from harm.In practice, many devices which require high currents and powers tend to work on the basis that it is the signal voltage which determines the level of response, and they then draw the current they need in order to work. For example, it is the convention with loudspeakers that the volume of the sound should be set by the voltage applied to the speaker. Despite this, most loudspeakers have an efficiency (the effectiveness with which electrical power is converted into acoustical power) which is highly frequency dependent. To a large extent this arises as a natural consequence of the physical properties of loudspeakers. We won’t worry about the details here, but asa result a loudspeaker’s input impedance usually varies in quite a complicated manner with the frequency. (Sometimes also with the input level.)This kind of behavior is quite common in electronic systems. It means that, in information trms, the signal pattern is determined by the way the voltage varies with time, and ideally the current required is then drawn. Although the above is based on a high—power example, a similar situation can arise when a senor is able to generate a voltage in response to an input stimulus but can only supply a very limited current. In these situations we require either a current amplifier or a buffer. These devices are quite similar, and in each case we are using some form of gain device and circuit to increase the signal current level. However, a current amplifier always tries to multiply the current by a set amount. Hence it is similar in action to a voltage amplifier which always tries to multiply the signal current by a set amount. The buffer differs from the current amplifier as it sets out to provide whatever current level is demanded from it in order to maintain the signal voltage told to assert. Hence it will have a higher current gain when connected to a more demanding load.The nature of electrical signals in electronic circuits readily enables the technology to be divided into classes.One of the classes is analog electronics; another is digital electronics.Both analog and digital electronics use similar electronic elements,but the manner of use is different , and the technologies appear to be quite distinct .For this reason we shall study them separately until we bring them together as they invariably unite in instrumentation and applications.Analog electronics pertains to those systems in which the electrical voltage and electrical current are analogous to physical quantities and vary continuously. Electronic circuits that reproduce music must have voltages and currents that are proportional to the sound. A high fidelity amplifying system attempts to keep the analogy as true as possible.Analog electronic circuits are carefully designed to make the electrical voltages and currents follow the input signal.If an input signal doubles in amplitude,the output voltage or current also should double;this is possible because the circuit elements are made to operate within limits that preserve the linearity.An electrical voltage that is proportional to temperature and changes smoothly as the temperature changes is an analog of temperature.If the temperature range is divided into small increments,then the temperature may be indicated by a digital display.As the temperature (voltage) changes smoothly,a decision must be made by an electronic system as to the numerical value to be displayed as the temperature.The circuit making the decision is called an analog-to-digital converter,ADC.The inverse process is accomplished by a digital-to-analog converter,DAC.Digital electronic circuits do not require the linearity of analog circuits.Digital circuits act as electronic switches and switch from one state to another.The output state,on or off, is the only signal condition to be examined.In digital circuits the output state is determined by the input signals in as direct a manner as the output voltage of an analog circuit is related to the input signal. In digital circuits the relation between input and output states are expressed as logic equations; the elements of digital electronics are called logic gates. Logic gates switch between states,on or off, very quickly so that they may operate at many megahertz in computers and otherapplications.As technical developments continue to provide new and amazing integrated circuits,as they have since the 1960s,both analog and digital systems will be more capable. The designers of electronic systems using integrated circuits will have unlimited possibilities for innovation.一般情况下，信号放大器正如人们期望的一样工作---将信号放大。

外文翻译--检验贸易平衡和汇率之间的关系：以中国与美国为例子

原文：Examining the relationship between trade balance and exchange rate: the case of China’s trade with the USAIn this paper, we investigate the nexus between China’s trade balance and the real exchange rate vis-a`-vis the USA. Using the bounds testing approach to cointegration, we find evidence that China’s trade balan ce and real exchange rate vis-a-vis the USA are cointegrated, and using the autoregressive distributed lag model we find that in both the short run and the long run a real devaluation of the Chinese RMB improves the trade balance; as a result, there is no evidence of a J-curve type adjustment.1、IntroductionThere is now a large literature that examines the nexus between trade balance and real exchange rate on developing countries (see, inter alia, Narayan and Narayan, 2004; Wilson and Tat, 2001; Lal and Lowinger, 2002; Kale, 2001; Singh, 2002). Recent empirical literature for developing countries finds a J-curve type adjustment of the trade balance due to shocks in the real exchange rate. For instance, Wilson and Pat (2001) do not find any evidence of the J-curve for Singapore. Lal and Lowinger (2002) find evidence of the J-curve for a group of East Asian countries; Kale (2001) finds evidence of the J-curve for Turkey; and Narayan and Narayan (2004) find evidence of the J-curve type adjustment of the trade balance for Fiji.1.We investigate the r elationship between China’s trade bala nce and its exchange rate vis-a-vis the USA dollar. Our approach is as follows: (1) to investigate evidence for contegration, we use the bounds testing approach; (2) to estimate the long-run and short-run elasticity, we use the autoregressive distributed lag model suggested by Pesaran and Shin (1999); and (3) to estimate the impact of shocks to exchange rate on the trade balance, we apply the impulse–response functions.The paper proceeds as follows. The next section presents the trade balance model to be estimated. This is followed by a brief description of the methodology used in this study. The penultimate section contains the empirical findings. In the last section, the results are discussed.Model and MethodologyModelOur model is as follows:Ln EMt =α+β1lnRERt + εtwhere ln EMt is the logarithm of the real exports to real imports ratio; ln RERt is the logarithm of the real exchange rate (RMB per US dollar), defined as the number of units of domestic currency per unit of foreign currency; α is a constant; and εt is a error term. According to the J-curve hypothesis, an increase in real exchange rate initially reduces the demand for the home country’s exports but increases its demand for imports. This initially leads to a deterioration of the trade balance due to the belief that imports in local currency increase more than the initial increase in exports after a change in price. However, as export and import volumes adjust to price changes over time, the trade balance improves. Hence, it is expecte d thatβ1＞0.MethodologyTo implement the bounds testing procedure, it is essential to model Equation 2 as a conditional autoregressive distributed lag model (ARDL) as follows:Here, all the variables are as previously defined. The bounds test for examining evidence for a long-run relationship can be conducted using either the F-test or the t-test. We find that in the long run, a 1% increases in the real exchange rate leads to a 1.2% increase in the export to import ratio, implying an improvement of China’s trade balance relative to the USA. This result is statistically significant at the 1% level of significance. In the short run, we find that a 1% increase in the real exchange rate leads to a 0.5% increase in the trade balance. This result is also statistically significant at the 1% level. The error correction term ECt-1, which measures the speed of adjustment to restore equilibrium in the dynamic model, has a negative sign and is statistically significant at the 1% level ensuring that the series is non-explosive and that long-run equilibrium is attainable. The coefficient of -0.42 implies that a deviation from the long-run ME ratio during this period is corrected by about 42% in the next period – an indication that, following a shock, convergence to equilibrium is swift, taking slightly over two years.Impulse–response functionRecent studies (Lal and Lowinger, 2002; Narayan,2004) on the J-curve recommend that the best way of deriving evidence of the J-curve is by using the impulse–response functions. We find and plot the response of trade balance to one standard deviation shock to real exchange rate in Fig. 1, and the response of exchange rates to one standard deviation shock to the trade balance in Fig. 2.The impulse–response function reveals that a one standard deviation shock to the real exchange rate (or devaluation of the RMB) leads to a very volatile response of trade balance for the first three years. After three years, however, the impact of shocks to real exchange rate on the trade balance dies out. Moreover, there is no evidence of any J-curve type adjustment of the trade balance.ConclusionThis paper examines the nexus between China’s trade balance with the USA and the real exchange rate. The test for a long-run relationship between trade balance and real exchange rate is based on the bounds testing approach. while the short-run and long elasticities are estimated using the ARDL estimator. We gauge the response of trade balance to one standard deviation shock to the real exchange rate using the impulse–response function. Our findings are as follows: (1) we find that China’s trade balance and real exchange rate vis-a`-vis the USA is cointegrated; (2) the long-run and short-run elasticities on the real exchange rate are positive and statistically significant, implying that a devaluation of the real exchange rate improves China’s trade balance; and (3) the impulse–response analysis suggests that a one standard deviation shock to real exchange rate creates a lot of instability in China’s trade balance for the first three years but the impact of this shock dies out thereafter.An important distinction between the present study and the literature on developing countries is that while most studies on developing countries find a J-curve type adjustment of the trade balance to shocks in real exchange rate, China’s experience is different: a real devaluation improves the trade balance in both the short run and the long run, which may be part of the reason for China’s exceptional export performance.外文题目Examining the relationship between trade balance andexchange rate: the case of China’s trade with the USA出处：Applied Economics Letters作者：Paresh Kumar Narayan检验贸易平衡和汇率之间的关系：以中国与美国为例子摘要在本文中，我们探讨中国与美国之间贸易平衡和实际汇率的的关系。
