摘  要： 论文、学术著作中外文资料比例越来越大，学习先进的技術知识需要更高的英语水平。而人工翻译成本高、效率低，已经无法适应发展需求，于是需要在科技英语的辅助系统上寻求突破口。Trados作为现今主流辅助翻译软件，可大幅度提高翻译效率和质量，同时降低翻译成本。文中基于Trados系统研究一种适应科技英语特性的高效辅助系统设计，提出翻译记忆模型，采用精准对齐的方式实现记忆库查询与校验操作。同时建立相似度规划算法，以“编辑距离”估算语言模糊匹配，实现更贴近语境语义的翻译效果。最后进行语料翻译测试，其数据结果表明，该种基于Trados平台开发的辅助翻译系统在科技英语翻译方面，词法准确率与专业性均较高。

Abstract： Due to the increasing proportion of foreign language materials in papers and academic works， learning advanced technical knowledge requires a higher level of English. In allusion to the manual translation can no longer meet the development needs on account of the high cost and low efficiency， a breakthrough in the auxiliary system of the scientific English need to be found. As the mainstream assistive translation software， Trados can greatly improve translation efficiency and quality while reducing translation costs. A design of the efficient auxiliary system adapted to the features of scientific English is studied based on the Trados system. The translation memory model is proposed， and the memory query and verify operation are achieved by means of the precise alignment method. The similarity programming algorithm is established， and the language fuzzy matching is estimated by "editing distance"， so as to achieve the translation effect that is closer to the context semantics. The translation test of corpus was conducted. The data results show that the auxiliary translation system developed based on the Trados platform has a higher lexical accuracy and professionalism in the translation of scientific English.

随着世界一体化发展趋势，各国交流日益密切，学术圈子已经覆盖到全球各国。而科技英语作为学术通用语言，其翻译质量决定着学术思想、成果的传递效率。传统的纯人工翻译成本代价过高且效率低，无法满足日益增长的翻译需求[1]。再加上万物互联时代下，人工智能大数据的蓬勃发展，计算机翻译已然成为发展的必然趋势，也是翻译效率提升的突破口。为此，人们对现行的辅助翻译系统提出了新的需求。

现今，国内主流辅助翻译软件有SDL Trados，DAVU，CAT等，其中Trados市场占有率最高[2]，达到78%。另外，Trados充分利用了“翻译记忆”的理念，将翻译过的文本储存到记忆库中，遇到类似的文本便可综合以前的翻译结果，从而得到更加精准，且贴合语义的翻译结果。……
