计算机辅助翻译方便了译者的工作,但因为文化缺项以及语言经验不同导致了词汇缺项和词汇不对等,又因为机器翻译不能灵活变通,从而产生了“不可译”现象,制约着CAT的翻译质量。这不能通过改进CAT语言规则分析的运行方法来改良,只有通过扩大CAT工具的相关语料库,共享更多语料库资源,才能使不可译的范围缩小,增加翻译效率。 Computer-assisted translation facilitates the translator’s work, but due to the lack of culture and language experience led to a lack of vocabulary and vocabulary is not equal, and because machine translation can not be flexible, resulting in “untranslatable ” phenomenon, restricting CAT translation quality. This can not be improved by improving the operation method of CAT language rule analysis. Only by expanding the corpus of CAT tools and sharing more corpus resources can the scope of untranslatability be narrowed and the efficiency of translation can be increased.
