科技英语翻译科技英语（English for Science and Technology，简称EST）是从事科学技术活动时所使用的英语，是英语的一种变体（科技文体）。

科技英语自70年代以来引起了人们的广泛关注和研究，目前已发展成为一种重要的英语语体。

本节所讨论的科技英语主要指描述、探讨自然科学各专业的著作、论文、实验报告，科技实用手段（包括仪器、仪表、机械、工具等）的结构描述和操作说明等。

一、科技英语的文体特点科技英语由于其内容、使用域和语篇功能的特殊性，也由于科技工作者长期以来的语言使用习惯，形成了自身的一些特点，使其在许多方面有别于日常英语、文学英语等语体。

这些特点主要表现在词汇和句法两个层面上：（一）词汇层面（1）专业术语多。

专业术语指某一学科领域所特有或专用的语汇，其词义常不为专业外读者所明白，如cryogenics （低温学）、norepinephrine （新肾上腺素）等。

这些专业术语的特点是：a. 词形较长，大多含有源于拉丁语、希腊语和法语的词根、词缀。

这类词语的语义范围较为狭窄，意义较为明确固定，符合科技英语准确明晰的要求。

如：nucleonics （核子学），semisomnus （半昏迷），autoradiography （自动射线照相术），excoriation （表皮脱落）等。

b. 多复合词。

人们常常通过各种构词方法创造出一些复合词来表示科技发展中出现的新事物，如radiophotography （无线电传真），anti-armored fighting vehicle missile（反装甲车导弹）等。

c. 多缩略词。

为使用便利和节省时间，科技英语同经贸英语一样，也有许多缩略词，如cpd （compound化合物），FM （frequency modulation 调频），telesat（telecommunications satellite通讯卫星）等。

（2）准专业术语和词汇多。

科技英语的特点与翻译一、科技英语的特点科技英语（English for science and technology，EST）指与用于科学和技术交流方面的英语口语和书面语。

作为一种重要的英语语体，其特点主要体现在以下几个方面。

1、词汇方面大量使用专业词汇、复合词、缩略词及利用前后缀构成的派生词。

专业词汇意义专一，用来表示明确的含义。

科技词汇多源于希腊语和拉丁语，是因为这两种语言作为英语的重要来源，是世界上成熟最早和最完备的语言中的两种，词汇不再发生词形、词义上的变化，具有稳定性。

2、句子方面多使用长句和被动语态，大量使用名词化结构（nominalization）和非限定动词。

另外，各种成份（如介词短语、形容词及其短语、副词、分词及从句等）作定语并后置，多使用It…that…结构句型、被动结构句型、as结构句型、分词短语结构句型和省略句结构句型等常用句型。

名词化结构有利于行文简洁、表达客观、内容确切，也可使所含信息量增大，尤其是科技英语强调存在的事实，而非个别行为。

不定式短语、-ing分词短语和-ed分词短语这三种非限定动词形式具有齐备的语法功能，可代替各种从句，这样既可缩短句子，行文简练，结构紧凑，又比较醒目。

3、形态方面科技英语在时态运用上有限，多用过去时和现在时。

尤其是多用一般现在时，以表述无时间性的科学定义、定理、公式、现象、过程等。

另外，科技英语多用逻辑性语法词（logical grammatical operators），如表示原因的如because (of)、due (owing) to、as (a result of)、caused by、for等，表示语气转折的如but、however、nevertheless、otherwise、yet 等，表示逻辑顺序的如so、therefore、thus、furthermore、moreover、in addition to等。

4、文体方面科技英语注重行文的连贯（coherence）、清晰（clarity）、流畅（fluency），避免行文晦涩、表露个人感情、过多运用修辞手法等。

实用科技英语翻译研究所谓“通顺”，就是在确切理解和掌握原文的基础上，汉语译文必须规范化，用词造句应符合汉语表达习惯，力求通顺易懂。

要摆脱原文形式的束缚，不要逐词死译，生搬硬套，选用符合汉语习惯的表达方式，把愿意清楚明白的再现出来。

科技译文的通顺还要符合专业表达的习惯，采用规范的专业语言，只在形式上忠实于原文，还不算是好的译文。

在EST翻译中，陆殿杨提出一条原则:“Translate literally, if possible, or appear to free translation.”(能直译就尽量直译，不能直译就采取意译。

)译好科技英语需要具备的三个条件：对英语要比较精通（Good command of English）;汉语水平要比较高（Good command of Chinese）;对有关的科技内容要比较熟悉，即知识水平（Familiarity with Knowledge of Science and Technology）一般来说，从事科技翻译工作，最好是通晓外语的本行专家，由熟悉本行业的行家翻译出来的东西，远比精通外语的门外汉要强得多。

严复翻译的三字标准“信、达、雅”。

求其信，已大难矣！故信矣，不达，虽译，犹不译也，则达尚焉。

易曰修辞立诚，子曰词达而已，又曰言之无文，行之不远。

三者乃文章正轨，亦即为译事楷模，故信达而外，求其尔雅。

此不仅期以行远已耳，实则经理微言。

用汉以前字法句法，以为达易；用近世利俗文字，以求达雅，往往意义就词，毫厘千里。

审择于斯二者之间，夫固有所不得已也。

（《天演论》译例言，1898）林语堂：忠实、通顺、美傅雷：神似钱钟书：化境对于“美（雅）”，尚有争议。

但“忠实”和“通顺”已成公认标准。

1. Relatively little research has been centered on the feeding behavior of this species because of difficulty in its detection and capture.2. This conclusion, however, was based on limited feeding observation and irregular occurrence of these “sap-site” trees.3. Other studies conducted analysis on faecal samples from north Queensland and Victoria respectively to determine feeding behavior.4. These studies found…….5. Qualitative observations of feeding behavior in gliders have also been carried out.6. This study aims at achieving this by addressing the following question.7. During a ten-year period of time, the number of HIV-infected children rose from 250 in 1985to 6700 in 1995.In other words, the number of HIV-infected children under 12 increased by almost 3000%, or nearly 30 times over a ten-year period of time and during the same period of time 3811 child died of AIDs.8. Registered students from Henan were 49 in 2001, 50 in 2002 and 47 in 2003. So changes are small with regard to this group over the last three years. Turning to students from Shandong, we find the figure 34 in 2001, and in 2002, the number was almost doubled to settle around 67. In 2003, it fell to 42. The last group is students from Shanxi. As you can see, the number was cut down by half in 2003 compared with the number in 2001.9. Although studies have shown that diet has an important influence on a mammal’s overall biology, little is known about the feeding ecology of many Australian species.10. Advanced ceramic materials such as zirconia have great potential as substitutes for traditional material in many engineering applications; however, a number of problems have thus far restricted their use by engineers. Two of the major problems are difficulties in producing products of reliable and consistent quality and high cost of manufacture.11、The motion of ions is the motion of such atoms as have gained, or lost electrons, which in most cases takes place in chemical solutions.离子的运动，也就是已经得到或失去电子的原子的运动，这种运动大多发生在化学溶液中。
