1、科技英语词汇与翻译从事科技文献翻译和其它翻译一 样，首先碰到的便是词的翻译。要想 处理好词的翻译，必须要有足够的词 汇量，同时还需了解科技英语词汇的 来源与特点，掌握词的构成方式及翻 译技巧。I. 科技英语词汇的来源及构成n One of the most distinctive features of EST is its technical terms, which not only account for a large part of English vocabulary, but also are the most important source of newly coined w

A mastery of them will benefit us a great deal in the translation of EST.classification of technical wordsnsingle words ( robot, internet, etc.)，ncompound forms ( e.g. feedback 反馈， splashdown 溅落，) nphrases on-and-off-the-road路

4、科学技术一方面仍直接从拉丁语、 希腊语借用术语，而另一方面又利用拉丁语 、希腊语的词根，加上英语、拉丁语、希腊 语的词缀构成无穷无尽的科技词汇。 e.g. science plateau(高原) 借自波斯语的有: shawl(披肩)，bazaar(市场); 借自印地语的有: nabob(大富翁); 借自意大利语的有: fresco(壁画); 借自德语的有: anti-body(抗体); blitz (闪电战) 借自西班牙语的有: canyon (峡谷 ), mosquito (蚊子) 借自阿拉伯语的有: algebra(代数), alcohol (酒精)2. 通过构词法(Word format

The advantage of affixation is evident: it is the most flexible means of forming new words and its potential of creat
6、ion is almost boundless, therefore it is extensively used in the formation of technical terms. Affixation/derivationnBesides prefix and suffix of English origin, there are some foreign borrowings, noticeably the Latin ones, e.g. bio-（生物 ，生命）, thermo-（热）, electro-（电）, aero-（空气）, carbo-（碳）, hydro-（水 ）

9、ng)Two or more words combined t form a new word is called compounding. English technical terms formed by compounding generally take three forms: combining with a hyphen ( e.g. salt- former 卤素， dew-point 露点， pulse-scaler 脉 冲定标器) or without it ( e.g. fallout 放射性尘埃， hovercraft气垫船， waterlock 水闸， thunder

13、d accurate.从上述例子可以看出，科技英语中大 量使用复合名词和复合形容词。复合动词 的使用是现代英语中一种比较简练的表现 手段。如果不用复合动词来表达，句子会 冗长拖沓。但复合动词的使用范围有一定 的局限性，不宜任意套用。对这类动词本 身，也要区别对待:有临时性词语，时过境 迁不再使用;有些富于表现力，能比较长期 地保存下来;在翻译过程中，一定要多注意 这些词。203.
