爆炸火焰国内研究态势科学知识图谱分析

Analysis of the Mapping Knowledge Domains on explosive flame researches in China

为了解我国在爆炸火焰方面的研究态势,基于中国知网数据,统计分析了相关专业期刊近20 a刊登的论文,并利用CiteSpace V软件绘制爆炸火焰国内研究态势科学知识图谱。结果表明:从论文发表机构看,中北大学化工与环境学院、中国矿业大学安全工程学院和河南理工大学安全科学与工程学院这3个机构在爆炸火焰方面的研究处于领先地位,在爆炸火焰领域做了大量研究,但从总体看,单位与单位之间的合作较少;从作者合作方面看,呈现作者与作者合作较为紧密的良好态势,从发文数量看,中国人民解放军后勤工程学院的杜扬教授、中国矿业大学的林柏泉教授等均在20篇以上,他们的研究成果为该领域的发展奠定了基础。分析研究热点知识图谱,结果表明:研究热点随着时间推移而发展、变化,但总体上呈现发文量逐年增多、研究领域逐年拓宽的趋势;在前沿分析方面,高频词的变化反映了近些年科研人员在气体爆炸方面的研究较为充分。

In order to study the research situation of the explosive flame in China,the statistical analysis of published papers in the main journals in the past 20 years was made based on the data of China National Knowledge Infrastructure(CNKI).By using CiteSpace V software,the Mapping Knowledge Domains was drawn to reflect the domestic research situation of explosion flame.The results showed that,according to published institutions,the three scientific research institutions,i.e.,school of Chemical Engineering and Environment of North University of China,the School of Safety Engineering of China University of Mining and Technology and the School of Safety Science and Engineering of Henan Polytechnic University,were in a leading position in explosion flame researches.They have done a lot of research works in the field of explosion flame.But in general,the cooperation between the institutions was still relatively lacking.In terms of the authors’analyses,the cooperation between the authors was relatively close.In terms of the output volume,professor Du Yang of the PLA Logistics Engineering College and professor Lin Baiquan of China University of Mining and Technology,all has published more than 20 articles,and their research laid the foundation for the development of this field.The analysis of research on hotspot knowledge map showed that the research on hotspot developed and changed with the passage of time,but the overall trend was that the number of published papers increased year by year,and the research field expanded year by year.In terms of frontier analysis,the variation of high-frequency words reflected that researchers have done a lot of works on gas explosion in recent years.
