“信”和“faithfulness”是中西方传统翻译理论中两个有关翻译原则的重要概念。由于翻译原则以及建构其上的翻译理论对各自文化中的翻译实践有指导意义,因而具体的翻译策略和译文的社会影响就会产生不少差异,主要表现在三个方面:译文形式与原文形式在考虑上的优先性、译文在目标语文化体系中的角色以及译者的社会地位。 “Letter ” and “faithfulness ” are two important concepts of translation principles in traditional Chinese and western translation theories. Because the principle of translation and the construction of its translation theory have guiding significance to the translation practice in their respective cultures, the specific translation strategies and the social influence of the translation will have many differences, mainly in three aspects: the translation form and the original form The priority of consideration, the role of translation in the target language system and the translator’s social status.
