摘　　要：在实验的基础上,研究了管内瓦斯爆炸过程中爆炸波结构变化规律。研究结果表明,管内瓦斯爆炸过程中所产生的爆炸波有两个峰值,第一峰值为爆炸波压力,第二峰值压力为火焰到达后加热气体升压所致。形成激波后,爆炸波两峰值往下游传播越来越靠近,测试结果与爆炸传播理论是相互验证的。The structure variation law of explosion wave in gas explosion was studied on the basis of experiment. The result shows that there are two peak values, the first one is explosion wave pressure; the second is caused by the hot gas, which is heated by the subsequent flame. When the shock wave is formed, the propagation velocity of the two peak values of explosion wave, become nearer and nearer, that is reciprocally authenticated with the explosion propagation theory.
