功能对等理论视角下的科技英语翻译 摘要：科技英语翻译作为翻译领域内重要的组成部分之一，在国际交流中占重 要地位。科技英语本身所具有的准确、简洁、严谨和客观等特征使译者在翻译科 技文本时需要具有更高的要求。本文旨在从功能对等理论的视角下探讨科技英语 的翻译策略。本文在奈达的功能对等理论视角下进行分析研究，从语义和风格两 方面提出了科技英语的翻译策略，对科技英语翻译质量的提高有积极的指导作用。关键词：科技英语翻译；功能对等；翻译策略 一、科技英语的特点 随着科技的迅速发展，国与国之间在科技方而的交流日益频繁，科技英语 材料越来越多，科技翻译也就显得越来越重要。科技英语是一种信息型的文体， 其主要用途是传递信息。它具有叙述客观、严谨周密、概念准确、逻辑性强、行 文精炼、句式严整等特点，名词化结构因其客观、准确的特点而被频繁应用于科 技英语中。 与文学类语言相比，科技英语有其显著的语言特征，主要体现在词汇和句 法特征两方面。词汇上的差别是科技英语区别于文学语言最显著的特征之一，即 大量使用专业术语。科技领域内的工作人员都倾向于使用客观、直接、简洁的语 言和词汇来描述事物。总的来说，科技英语在词汇方面的特点主要体现在以下几 个方面：（一）将普通词汇专业化形成专业技术词汇。科技英语中的很多专业术 语都是通过赋予普通英语词汇新的含义而得来的，为了熟悉专业术，功能对等视 角下的科技英语翻译语，译者必须阅读大量的专业领域的科技文本，以使翻译成 品更专业准确。（二）借用其他学科词汇形成半专业技术词汇。半专业词汇是由 普通词汇转化演变而来，本身含有一般词义，但在不同学科和专业中有不同的意义。（三）广泛使用缩略词。为了表达简洁方便，科技英语中都会使用大量的缩 略语。为了体现其客观准确性，避免带有主观色彩的叙述，科技英语会较多地使 用被动语态，名词化结构以及各种复合句。名词化结构有利于达到交际目的，派 生名词的使用则可以有效简化叙事层次和结构，减少从句的使用频率，使科技英 语的行文更加直接、精炼，达到较少的篇幅表达更多的内容，从而使文篇更简洁、浓缩和凝练。 二、功能对等理论 “功能对等理论”的创始人是美国著名翻译学家尤金奈达，他在著作《翻译科学探索》中首次提出“动态对等”的概念。该理论一经提出，就在当时的翻译界产 生了很大反响。在后来出版的《翻译理论与实践》中，他对“动态对等”做了明确 定义：动态对等就是“译文读者对译文信息的反应与原文读者对原文信息的反应基本一致”。尤金奈达指出所谓动态对等翻译是“在译入语里产生和源语信息最切近 的自然对等语”，其中包括三个方面，即形式、内容、读者的反应。其中内容和形式是基础，读者的反应是核心。奈达认为内容比形式更重要。奈达的功能对等是 相对意义上的对等，是相对程度的接近，不可能做到绝对的对等，因为每个民族 的思维方式不完全相同。 功能对等理论是一种活应范围很广的翻译理论，之所以能出现科技英语名 词化结构的翻译，主要是以下原因。首先功能对等理论目标是通过在译入语里产 化与原文信切近的对等语，实现原文和译文在风格和意义上的对等，这点是对所
2009-2010学年第2学期 《实用科技英语翻译》期末考试题型和复习题 I Answer the following questions related to EST Translation (30’)（2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 widely 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 this common feature 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.

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)
试谈科技英语说明书的特点及翻译策略 科技英语说明书兼具科技英语和说明书的特点，即客观[3]、专业性强、逻辑性强、术语多，说明少等特点。笔者针对此类文体，提出“准确、通顺、简练”的翻译标准，并分别探讨了每个标准。 标签：科技英语说明书翻译 一、科技英语说明书的特点 科技英语说明书是科技文章的一类，既有科技英语的一般共性，又有其独特的个性。与非科技英语相比，科技英语里的复杂长句比较多，一句话里包含三个以上子句的情况是常见的，包含五六个子句以上的情况也决非个别。这是由于科技文章要求叙述准确，推理严密致。其次，科技英语中被动句使用频繁。被动句中把受事作为句子的主语，突出强调动作的承受者，即动作执行的对象。受事在科技文中通常表现为客观事物，科技文章着重叙述客观事实，并希望强调所论述的事物，所以多采用以客观事物为主体的被动语态。此外，非限定词使用较多和词性转换较多也是科技文章的显著特征，在此不再赘述。科技英语说明书作为科技文章的一种个性，除兼具以上特征之外，还有自身的特点，如术语密集，列举物件多而说明少。因为读者多半是直接使用者，事先已经知道这些术语。因此，翻译时要注意这些术语的标准译法。另外，说明书的使用者为产品的购买者，文中出现“you”的地方，一律翻译为“您”表示尊敬，但对于原文中的警告、注意事项，译文也要采取相应的警示语气，提醒使用者注意[4]。 二、科技英语说明书的翻译策略 严复的“信、达、雅”可谓翻译的“三字真经”，结合科技英语说明书的特点，仿照严复的三字论及国内其他学者对应用文体提出的翻译标准，笔者提出三词论——“准确、通顺、简练”作为科技英语说明书的翻译标准。阎庆甲[5]在《科技英语翻译方法》一书中提出“明确、通顺、简练”的科技翻译标准，黄洁[1]《科技文翻译之实、准、简—译Harmony有感》一文中引用了李长栓[2]（2008）对应用文写作的三字基本要求“实、准、简”。实，实质内容要求实事求是。准，是表达形式、语言、引用事例、数字、图片都要准确无误;简，就是简洁明了，要直截了当，不说套话、废话、不绕弯子。此理论可谓面面俱到。笔者认为科技说明书，目的在与介绍国外先进仪器设备的使用方法，若翻译不正确，轻则对使用者产生困扰，重则产生危害。因此，译文在技术内容上要忠实于原文，不应有模糊不清，模棱两可的地方。准确，应为科技说明文翻译的最高标准。通顺，是说译文要符合目的语的语法特点，行文习惯。可通过长句拆分，词性转换和调整句序，使读者易懂。简练就是译文要尽可能简短，精炼。不啰嗦赘余，力求寻找翻译原文本最言简意赅的表述。简练为科技说明书最高翻译标准，是建立在准确、通顺的基础之上的。对于一般的科技说明书而言，做到准确、通顺即可。 （一）科技说明文之“准确”

The pattern of sharing in tasks and in decisions makes for equality, and this in turn leads to further sharing. In such a home, the growing boy and girl learn to accept that equality more easily than did their parents and to prepare more fully for participation in a world characterized by cooperation rather than by the "battle of the sexes".
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
