摘　　要：本论文以石油与天然气工程学科(简称:石工学科)为例,从历时角度出发,通过自建语料库、采用定性与定量相结合的研究方法,讨论分析了石工领域专业词汇的历时变化特征。研究发现,石工学科核心专业词、准专业词覆盖率趋于增长,准专业词的搭配词义科技性增强,所构成的新词向核心专业词转化,其搭配范围随时间变化而不断扩大,石工学科的专业词搭配范围与词汇本身的词频、词义稳定性有关。This paper discusses,with the aid of qualitative and quantitative methods,the diachronic characteristics of the technical vocabulary in the field of petroleum and natural gas engineering by the use of self-built corpora.It finds that the coverage of core technical words and semi-technical words in this field tends to increase diachronically,and that the collocates of the semi-technical words contain more technical content,which are partly converting into new core technical words,and a large collocational scope with the passage of time.Moreover,the collational scopes of the technical words are related to their frequencies and stability in meaning.
