基于知识元分析的爆炸性环境点火源研究

Study on ignition source of explosive environment based on knowledge element analysis

采用知识元分析方法总结爆炸性环境点火源相关研究,呈现出现阶段点火源的相关研究知识结构。基于"概念-关系-问题"模型,剖析点火源的基本属性、易燃物质的引燃特性参数,分析其内在特征,进行关联约束,根据结果辨识了爆炸性环境点火源特征,提出预防性措施。分析结果表明:关于点火源本身的研究多集中于事故分析方面,对点火源自身的引燃特征研究相对较少,缺乏表征技术和实验测定模拟装置。在此基础上展望未来研究趋势。

The related research of ignition sources in explosive environment is summarized using knowledge element analysis method,and the knowledge structure of ignition sources at the present stage is shown.Based on the concept-relationship-problem model,the basic attributes of ignition source and ignition characteristic parameters of flammable substances are analyzed,their intrinsic characteristics are analyzed,and related constraints are carried out.The characteristics of ignition source in explosive environment are identified according to the results,and preventive measures are put forward.The analysis results show that the research on ignition source mostly focused on accident analysis,the study on ignition characteristics of ignition source itself is relatively few,and it’s lack of the characterization technology and experimental measurement simulation device.Based on the study,the future development trend is looked forward to.
