摘　　要：对不同初始压力和温度条件下的甲烷/空气混合气的爆炸极限进行实验研究,利用最大-最小准则来确定爆炸极限。分析了温度和压力对甲烷/空气混合气燃爆特性的影响。采用氮气作为惰性气体,对其防爆抑爆效果进行了实验研究。The flammability limits of methane/air mixture are investigated experimentally at different initial pressures and temperatures. The max - min criterion based on the maximum explosion pressure is used to define the flammability limit. The influence of initial temperature and pressure on explosion characteristics of methane/air mixture are analyzed. Using nitrogen gas as conversion gas,the explosion suppression effect of nitrogen gas is studied.
