Back Translation(反向翻译)

要求比较原文和反向译文的差异

反向翻译是将已经译成一种外语的文件反向翻译为原文件语言的过程，通常由独立的第三名译员来完成。反向翻译的目的在于通过第三者将译文反向翻译回原来的语言，以便与原文比较，来判断、提高原译文的可靠性和准确性。反向翻译是一种成本高、效果好的质量控制过程，欧洲的一些客户常常使用这种方法来提高翻译质量。
Back Translation is the process of translating a document that has already been translated into a foreign language back to the original language - preferably by an independent translator. Back translation can improve the reliability and validity of research in different languages by requiring that the quality of a translation is verified by an independent translator translating back into the original language. Original and back translated documents can then be compared.
