基于高影响力论文的材料科学领域研究主题演变分析

Analysis of Subjects Evolution in Material Science Based on the High Impact Papers

基于SCI数据库,抽取1979-2008年间材料科学领域的1004篇高影响力论文作为分析对象,从载文分布、中心学科变化、关键词演变等方面进行定量和定性分析。结果表明:材料科学领域呈现出学科分布多样化、多学科交叉融合等特征;热点研究主题由传统金属材料研究演进到无机非金属材料、高分子材料,由关注温度转为关注晶体生长状态、薄膜材料,复合材料获得了广泛的应用。

Based on Science Citation Index（ SCI）, the paper extracts 1,004 High Impact Papers on material science from 1979 to 2008 as objects of analysis. It conducts quantitative and qualitative analysis from such aspects as distribution of articles, changes in core subjects and evolution of key words. This paper points out that subject distribution in Material Science is diverse and integrated. The hot spot has shifted from traditional metal materials to inorganic materials and polymer materials development, with the focus being changed from on temperature to on the growth of crystal and thin-films materials. And composite materials have been widely applied.
