以体裁分析为基础,通过收集语言学、医学和计算机三门学科科研论文英文摘要300篇,使用卡方检验(SPSS)及EXCEL软件对其结构和语言特点进行对比分析,总结出不同学科科研论文英文摘要书写的共性和个性特点,并分析其产生的原因。结果显示三门学科的科研论文英文摘要在结构上有相似和不同之处:宏观结构上,语言学与医学,语言学与计算机科学没有明显差异(P>0.05),但医学与计算机科学差异明显(P<0.005);微观语言特点方面,情态动词和时态的使用不仅和学科有关,而且与语轮的交际目的有关,时态多采用一般现在时,语态多采用主动语态,可以出现第一人称。
On the basis of genre analysis, we collected 300 English abstracts of linguistics, medicine and computer science research articles from three disciplines, and compared their structure and language characteristics by using chi-square test (SPSS) and EXCEL software to summarize the dissertations of different disciplines English abstract writing characteristics of the common and individual, and analyze the causes. The results show that there are similarities and differences in the structure of the English abstracts of scientific papers of the three disciplines. There is no significant difference in linguistics and medicine, linguistics and computer science in the macro structure (P> 0.05), but the difference between medical science and computer science is obvious (P <0.005). In terms of micro linguistic features, the use of modal verbs and tense is not only related to disciplines, but also related to the communicative purposes of the language rounds. When the tense is mostly used nowadays, the modality uses more active voice and can appear First person.
