“难度系数”是跳水比赛的裁判术语,本文将之引入并提出“翻译难度系数”一说,探讨翻译难度评估标准,并且试图建立翻译难度系数计算方式。“翻译难度系数”的提出,对于指导翻译实践、翻译教学和翻译研究具有积极意义和应用价值。 “Difficulty factor ” is the referee term of diving competition. This article introduces and puts forward “the difficulty coefficient of translation”, discusses the assessment standard of difficulty of translation, and attempts to establish the calculation method of difficulty coefficient of translation. The proposed “difficulty coefficient of translation” has positive significance and application value for guiding translation practice, translation teaching and translation studies.
