词汇密度与难易度感知——科学论文及其摘要的对比研究

Lexical Density and Text Difficulty——A Comparative Study of Scientific Papers and Abstracts

本文以地学科技论文及其摘要为例,通过对比研究科学论文及其摘要的词汇密度以及词汇密度与难易度感知的关系,得出论文的词汇密度比摘要的词汇密度高的结论.为探讨篇章的词汇密度与篇章难易度感知的关系,笔者在中国地质大学(北京)的教师和博士生中做了调查,得出结论:由于科技论文及其摘要的关系的特殊性,虽然科技论文的词汇密度比摘要的词汇密度高,论文的感知要比摘要的感知容易.

s on the relationship between lexical density and text difficulty. The result shows that scientific papers in general have higher lexical density than abstracts. However, an investigation reveals that scientific papers are thought easier than scientific abstracts.
