等值论与功能主义都是西方学者对于翻译本质研究的两大对立理论派别。两大派系中等值论以奈达的功能对等理论为代表,功能派翻译理论则以费米尔的“目的论”为代表。本文将对这两大派别进行归纳研究并找出其对立统一面,为翻译理论的研究提供新的视角。 Equivalence and functionalism are two antithetical schools of the western scholars on the nature of translation. The middle value theory of the two factions is represented by Nida ’s theory of functional equivalence, while that of functionalist translation is represented by Fermi’ s “teleology”. This article will summarize these two major factions and find out their opposites and unity, providing a new perspective for the study of translation theory.
