On Translation Methods Of Compound Nouns In English For Science And Technology

English for science and technology （EST） refers to English which is used inscientific writings, papers, textbooks, science and technology reports and academiclectures on the aspects of natural science and engineering technology. EST uses thestructure of ellipsis and the passivity constantly, and it also uses a large number of thestructure of long sentences. The type of writing of EST are mainly argumentation andexposition, and its features are relatively objective, precise, distinct, strict and brief,and they are decided by the contents and characteristics of the scientific and technicalliterature themselves.

In Chapter2, it expounds the compound word and compound nounin EST, and introduces the existing current research situation of compound noun inEST. Chapter3is the focal point of the full thesis, and it analyzes the problems intranslation of compound nouns in EST in four angles, such as in conventionalunderstanding and translation, unconventional understanding and translation,translation on the level of semantic function and logical relationship. It alsoenumerates some cases to each kind of translation method and analyzes themspecifically.
