基于Web of Science数据库的我国二甲基硫气体研究状况的数量分析

Quantitative Analysis of Research Status on Dimethyl Sulfide Gases in China Based on Web of Science

利用Web of Science数据库的SCI-Expanded和CPCI-S子库的数据和分析功能,对1994—2009年期间我国二甲基硫研究的科研产出量、产出水平和国际合作等方面进行了分析。结果表明:我国关于二甲基硫的研究起步较晚,但是科研产出量整体增长速度非常快,尤其是在2004年后,我国二甲基硫研究进入快速增长期,与世界发达国家研究水平的差距越来越小,表现出很大的发展潜力。科研产出量在科研单位分布上表现出很大的不均衡性,中国科学院论文发表量在我国发表论文总量中远远高于其他科研单位,占总发表量的28.4%,在二甲基硫研究方面具有重要的地位。就MAI、平均被引频次、h指数、发表期刊水平和国际合作等方面的表现力而言,与世界发达国家相比,我国在二甲基硫研究领域的科研产出水平还有很大的差距,但是这种差距在时间变化上呈现逐渐缩小的趋势。

This paper analyzed the scientific research output,output level and international cooperation by data and anal-ysis capabilities from Web of Science database. The result showed that study on dimethyl sulfide in China is relatively late,while the scientific output growth is fast. In particular,research on dimethyl sulfide has been obviously accelerated since 2004,and the gap between China and developed countries gets smaller and smaller,showing an obvious potential for development . The distribution of scientific output in institutions is unbalanced,and the amount of papers of Chinese academy of sciences published is much larger than that of others,whose ratio is 28. 4% ,playing an important role in the in research on dimethyl sulfide. In terms of MAI,the average cited times,h index,impact factor and international cooperation,compared with the world＇s developed countries,there is a great gap in output status between China and developed countries,but this gap is gradually shrinking.
