摘　　要：在应用燃烧管来模拟煤矿井巷对瓦斯爆炸进行实验研究时发现,甲烷-空气混合气体在系统的某些控制变量连续变化时,在某一临界状态状态参数会发生突跃变化。应用突变理论对热效应下瓦斯燃烧爆炸过程的突变现象进行了分析。When the fire damp explosion is studied by using a combusting tube to simulate the laneway of the coal mine, it is found that a catastrophe phenomenon which is induced by the continuous changing of the state parameter for the methane-air mixture will happen. The catastrophe theory is used to study this phenomenon.
