摘  要

世界经济一体化、贸易全球化的迅速发展使中国的经济与贸易活动也越来越繁荣。作为国际交流的桥梁之一，外贸函电在国际贸易中发挥着不可替代的作用，国内外许多翻译人员对外贸函电的翻译作了大量研究。其中，奈达的动态对等理论一直得到高度评价。奈达在翻译理论与实践中写到，动态对等理论就是：翻译的质量就是当把原文的信息翻译成接收者的语言时，接收者的反应就要像原文接收者一样。为了证明奈达的动态对等理论适用于外贸函电英译汉翻译，本文采用了对比论证法，首先对比了奈达的动态对等理论和其他翻译家的对等理论，随后介绍贸函电词汇，句法，文体上的特点，最后将动态对等理论运用到外贸函电的英译汉翻译中，论证动态对等理论对外贸函电翻译的可行性。

Abstract

The rapid development of global economic integration and trade globalization   has increasingly brought the activities of economy and trade of China more prosperous. Being one of the bridges of international exchange, foreign trade correspondence plays an irreplaceable role in international communication. Plenty of studies have been carried out by translators both at home and abroad. Among them, Nida’s theory of dynamic equivalence has been highly valued. As Nida(1969) himself wrote in the glossary of The Theory and Practice of Translation, dynamic equivalence is the "quality of a translation in which the message of the original text has been so transported into the receptor language that the response of the receptor is essentially like that of the original receptors." In order to prove the applicability of dynamic equivalence theory to E-C translation of foreign trade correspondence, this paper mainly adopts comparative method. This paper firstly contrasts Nida’s dynamic equivalence theory to other theorists’ equivalence theories. Secondly, the language features of foreign trade correspondence are summarized from lexical, syntactic, and textual levels. Finally, the usage of dynamic equivalence in English to Chinese translation for foreign trade correspondence will be presented to prove that Nida’s dynamic equivalence theory is perfectly suitable for guiding foreign trade correspondence translation.

1 Introduction
   This paper explores how to apply dynamic equivalence in E-C translation of foreign trade correspondence from three aspects: lexical features, syntactic features and textual features.
1.1 Definition of equivalence theory
    Equivalence theory occurred as early as two thousand years ago. It means when translating, the translator should be faithful to the original ideas, style, and then make the translated text as smooth as original.
