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
