摘　　要：为预防和控制可燃气体及蒸气爆炸事故,对其特性参数进行研究,通过查阅国内外标准及文献,从标准体系及测试装置、爆炸特性参数测试研究现状2个方面分析近年来标准制定及测试研究的成果。分析发现:我国尚无现行气体及蒸气的最小点火能、最大爆炸压力及上升速率的国家标准,需尽快制定;目前测试研究集中于常温常压下单组分气体爆炸特性的测试,对多组分可燃气体的研究较少;此外,不同点火方式的点火能量对爆炸特性参数的影响研究较少。可从相关标准制定、点火能量对爆炸特性影响、多组分气体测试研究3个方面开展进一步研究工作。This work is aimed at the prevention and control of accidents caused by explosions of combustible gas and vapor and the study of their characteristic parameters.By reviewing domestic and international standards and literature,this paper reviews the results of standard formulation and testing research in recent years from two aspects:the standard system and testing apparatus,and the current status of testing research on explosion characteristic parameters.The analysis revealed that there is no national standard for the minimum ignition energy,maximum explosion pressure and maximum rate of pressure rise rate of gas and vapor in China,which needs to be formulated as soon as possible.Currently,testing research is focused on the explosion characteristics of single-component gases at normal temperature and pressure,while studies of multi-component combustible gases are relatively scarce.In addition,little research has been done on the effect of different ignition methods on explosion characteristics.Further research can be conducted in three areas:the formulation of relevant standards,the effect of ignition energy on explosion characteristics,and the testing research on multicomponent gases.
