系统功能语言学作为适用语言学,其基于语料库的相关研究方兴未艾。本研究基于自建的航空航天教科书语料库,同时参照BROWN语料库和LOB语料库,以语域理论中语境的语场、语旨和语式三个因素为切入点,讨论航空航天语域的词汇语法特征。研究发现,航空航天教科书的词汇语法特征在体现科技教科书功能的同时,也展现了航空航天语域的特点。
As a suitable linguistics, systematic functional linguistics is still in the ascendant in its corpus-based research. Based on self-built aerospace textbook corpus and referring to the BROWN corpus and LOB corpus, this study explores the vocabulary and grammar of aerospace domain by using the context, language and language of the context theory as the starting point feature. The study found that the lexical and grammatical features of textbooks in aeronautics and astronautics not only embody the function of science and technology textbooks, but also reveal the features of the aerospace domain.
