I Answer the following quesitions related to EST Translation (30’)（3个题）
1.What’s the definition of EST (English of Science & Technology)?
EST (English for Science & Technology or Technical English or Scientific English) is a special language variety wide ly used in the fields of science and technology. It’s believed that it first came to being in the 1950s along with the rapid development of science and technology, and it many researchers and scholars began to conduct investigation of the common features of this special genre including reading comprehension, writing and even translation.
2,What are stylistic features of EST?
Completely different from other genres such as everyday English, literature English, EST has its own stylistic features due to the specialty in content, field and discourse functions, and partly due to the unique habits of EST writers, which are mostly represented in lexical level and syntactical level.
3, What are the general features of Compound Technical Terms?
A. accuracy（确切性）: accurately reflect the nature of the concept
B. monosemy（单义性）: one sense for one word
C .systematization（系统性）:the individual technical terms in a given field should be in a specific level so as to constitute a common system
D. linguistically correct（语言的正确性）: in accordance with the word-formation in the same language
E. conciseness（简明性）: concise and easy to remember
F. motivation（理据性）: just as the name implies, one can know the meaning of the word.
G. stability（稳定性）: stable and unlikely to change
H. productivity（能产性）: once established, it is easy to produce more neologisms based the original one by means of word-formation
4, What are common rules for Technical Term Translation?
As such, we should deal with the relationship of the following aspects:
A. monosemy vs. conciseness monosemy is the priority
B. motivation vs. accuracy
As science knowledge is rather abstract, motivation in translation is preferred
C. stability vs. productivity Productivity is the priority
D. systematization vs. linguistically correct
Before translation of compound technical terms, we should be aware of the nature and tradition of Chines e word-formation.
E. Chinese language trait vs. conciseness
As for the numbers of characters, we prefer to use pair characters （偶数词语）or even 4-character expres sions（四字结构）.
II. Match the Following: (10’)（2个题）

V. Passage translation (20’)（1个段落）
Principle of Maglev
磁悬浮列车原理
Maglev is a system in which the vehicle runs levitated from the guideway (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconductiong magne ts on board the vehicle and coils on the ground.
磁悬浮列车是一个系统。在该系统中，车辆利用车在超导磁铁和地面线圈之间产生的电磁吸力或斥力从导轨（相当于传统铁路的轨道）上浮升起来。
Different from conventional wheel-on-rail system, the Transrapid accompolishes the functions of s upport, guidance, acceleration and braking by using non-contact electromagnetic instead of mechanic al force. Because there is almost no mechanical contact. Transrapid can run with lower noise, but re latively higher speed up to 500 km/h.
与传统的轮轨铁路不同，磁浮列车主要是依靠无接触的电磁力、而非机械力来实现支承、导向、加速和制动功能。由于列车运行中几乎没有机械接触，因而运行起来噪音很小，时速却可达500 公里。
The magnetic levitation system is based on the power of attraction between the electromagnets in the vehicle and the ferromagnetic stator packs in the guideway. In contrast to the conventional trai ns, the propulsion system for the Transrapid is not mounted in the vehicle but in the guideway. The long-stator linear motor in the guideway is divided into segments which are individually switched
on and off, with power only being supplied to the given segment as the train passes.
磁悬浮系统依靠列车上的电磁铁和导轨中的磁铁定子之间的吸力工作。跟传统列车不同，磁浮列车的驱动系统不安装在车辆上，而是在导向轨中。导轨上的长定子线性电机被分成区段，各区段均有独立开关，只有列车通过该区段是才有电力供应。
Electronically controlled support magnets located on both sides along the entire length of the veh icle pull the vehicle up to the ferromagnetic stator packs mounted to the underside of the guideway. 电子控制的悬浮磁铁贯穿车辆的两侧，这些磁铁使车辆被吸往安装在导轨下方的磁铁定子元件。
Guidance magnets located on both sides along the entire length of the vehicle keep the vehicle laterally on the track. Electronic systems guarantee that the clearance remains constant(nominally 1 0 mm). To hover, the maglev requires less power than its air conditioning equipment. The levitation system is supplied from on-board batteries and thus independent of the propulsion system. The vehic le is capable of hovering up to 30 minutes without external energy While travelling, the on-board b atteries are recharged by linear generators integrated into the support magnets.
贯穿车辆两侧的导轨磁铁使车辆水平悬浮在轨道上。电子系统可确保空隙恒定（即10毫米）。列车浮升所需的功量低于车辆空调设施所需。悬浮系统由车载电池馈电，因而与驱动系统无关。在没有外部能量输入的情况下，车辆也能悬浮大30分钟之久。而在运行过程中，车载电池可由配备于悬浮磁铁中的线性发电机充电。

小议科技英语翻译技巧 科技文体崇尚严谨周密，概念准确，逻辑性强，行文简练，重点突出，句式严整，少有变化，常用前置性陈述，即在句中将主要信息尽量前置，通过主语传递主要信息。科技文章文体的特点是：清晰、准确、精练、严密。那末，科技文章的语言结构特色在翻译过程中如何处理，这是进行英汉科技翻译时需要探讨的问题。现分述如下： 一、大量使用名词化结构 大量使用名词化结构（Nominalization）是科技英语的特点之一。因为科技文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实。而非某一行为。 Archimedes first discovered the principle of displacement of water by solid bodies. 阿基米德最先发展固体排水的原理。 句中of displacement of water by solid bodies 系名词化结构，一方面简化了同位语从句，另一方强调displacement 这一事实。 The rotation of the earth on its own axis causes the change from day to night. 地球绕轴自转，引起昼夜的变化。 名词化结构the rotation of the earth on its own axis 使复合句简化成简单句，而且使表达的概念更加确切严密。 If you use firebricks round the walls of the boiler, the heat loss, can be considerably reduced. 炉壁采用耐火砖可大大降低热耗。 科技英语所表述的是客观规律，因之要尽量避免使用第一、二人称；此外，要使主要的信息置于句首。 Television is the transmission and reception of images of moving objects by radio waves. 电视通过无线电波发射和接受活动物体的图象。 名词化结构the transmission and reception of images of moving objects by radio waves 强调客观事实，而"谓语动词则着重其发射和接受的能力。 二、广泛使用被动语句 根据英国利兹大学John Swales 的统计，科技英语中的谓语至少三分之一是被动态。这是因为科技文章侧重叙事推理，强调客观准确。第一、二人称使用过多，会造成主观臆断的印象。因此尽量使用第三人称叙述，采用被动语态，例如：Attention must be paid to the working temperature of the machine.应当注意机器的工作温度。而很少说：You must pay attention to the working temperature of the machine .你们必须注意机器的工作温度。此外，如前所述，科技文章将主要信息前置，放在主语部份。这也是广泛使用被动态的主要原因。试观察并比较下列两段短文的主语。 We can store electrical energy in two metal plates separated by an insulating medium. We call such a device a capacitor, or a condenser, and its ability to store electrical energy capacitance .It is measured in farads. 电能可储存在由一绝缘介质隔开的两块金属极板内。这样的装置称之为电容器，
科技英语中专业术语的翻译
科技英语中专业术语的 翻译 集团文件版本号：（M928-T898-M248-WU2669-I2896-DQ586-M1988）
科技英语中专业术语的翻译 1.意译：根据科技术语的含义，将其翻译成汉语里和它完全对等的名词就叫意译。对单个词语来说，意译也就是直译。意译法是最常用的翻译方法，它能使读者直接了解术语的含义。例子如下： ①firewall ．．．．．．．． ：防火墙 ②data mining ．．．．．．．．．． ：数据挖掘 ③automatic program control ．．．．．．．．．．．．．．．．．．．．．．． ：自动程序控制 2.形译：英语中有些科技术语的前半部分是表示该术语形象的字母或单词，翻译成汉语时可把这一部分翻译成表示具体形象的词，或保留原来的字母，这就叫形译。例子如下： I ．-．bar ．．． 工字钢、工字条；O ．-．ring ．．．． 环形圈；twist ．．．．．-．drill ．．．．．麻花钻；X ．-．Ray ．．．X 光；α．-．brass ．．．．． α黄铜[1] 3.音译：根据英语发音翻译成汉语里相应的词。科技英语中某些有专业名词构成的术语、单位名称、新型材料的名称等，在翻译时都可采用音译法。例子如下： gene ．．．． 基因；quark ．．．．． 夸克；Pentium ．．．．．．． 奔腾 celluloid ．．．．．．．．． 赛璐璐；nylon ．．．．． 尼龙 Hertz ．．．．．（Hz ）赫兹（频率单位）；lumen ．．．．．流明（光通量单位） 4.缩写词：英语首字母缩写词在科技新词中占很大比重，这类词如果译成汉语，就显得拖沓冗长，因此很多情况下干脆不翻译。例子如下： CPU ．．．：．C ．entral Processing Unit ．．．．．．．．．．．．．．．．．．．．(中央处理器) ASCII ．．．．．：．American S ．．．．．．．．．tandard ．．．．．．． C ．ode ．．． for ．．． I ．nformation ．．．．．．．．．． I ．nterchange ．．．．．．．．．． (美国信息交换标准码) ATM ．．．：．A ．synchronous ．．．．．．．．．．． T ．ransfer ．．．．．．． M ．ode ．．． (异步传输方式) 一些国际组织的缩写也常采用这种办法。例子如下： WTO ．．．(国际贸易组织)；UNESCO ．．．．．．(联合国教科文组织)；WHO ．．．(世界卫生组织)；IOC ．．． (国际奥委会)
科技英语翻译的原则_方法及技巧.
翻译是把一种语言里已经表达出来的事物用另一种语言准确流畅地进行重新表达的过程。与其他题材的文章相比,科技专业文章在内容、表达形式和风格上有很大的差别,具有科技性强、专业性强、逻辑严密、表达要求简练的特点,在翻译上力求准确全面、严谨明确和通顺简练。 1科技英语翻译遵循的基本原则 从科技文章的特点来看,大多具有以下几个特征:述说事理、逻辑性强、结构严密、术语繁多,语言严谨、数据精确。这就要求译文必须概念清楚、条理分明、逻辑正确、数据无误,尤其对定义、定律、公式、图表、结论等更应特别注意。科技英语作为特殊英语的一个分支,在词汇构成、遣词造句等方面都有其自身的特点,其语法结构不十分严密、语言习惯和汉语也有不少差别、词汇量大、词语繁多,因此科技英语翻译起来比较困难。另外,科技文章比较重视叙事逻辑上的连贯及表达上的明晰与畅达; 避免行文晦涩,避免表露个人感情,避免论证上的主观随意性。因此,科技英语翻译力求少用或不用描述性形容词以及具有抒情作用的副词、感叹词及疑问词,而是大量使用科技词汇、专业技术用语,译者应尊重客观事实,不能随意改动数据、回避不易翻译的文字,更不能加进自己的主观想象,进行自由翻译。 我国著名翻译家严复提出的“信、达、雅”三准则一直为不少翻译工作者所接受。 “信”指的是译文要忠实于原文,“达”是指译文的通顺达意,“雅”指的是译文的用词修辞。三准则体现了译文和原文信息等值这一基本要领。 “信、达、雅”的翻译准则对各种英语文体的翻译实践都具有指导意义,是衡量一篇译文好坏的标准,也同样适用于科技文献的翻译。由于科技文章特有的文体特征,与其他类文章相比,其“达”和“雅”的内涵不同,它要求在准确传达信息的基础上,使译文更加简洁明快,流畅通顺。2科技英语翻译的基本方法
