摘　　要：研究了瓦斯爆炸过程中激波产生的影响因素，利用可压缩流体动力学与热力学基本原理，分析了瓦斯爆炸破膜时的热力动力问题，并计算出爆炸试验管内破膜时的主要热力参数。研究结果对于现场如何防治瓦斯爆炸，减轻瓦斯爆炸灾害具有一定作用。The paper conducts a study of the factor that influences the generation of shock waves during methane explosions, and by basing on the principles of compressible fluid dynamics and thermodynamics, makes an analysis of the thermodynamic problem in the methane explosion and membrane - breaking process together with a calculation of the major thermal parameters, which is made as the membrane in the explosion test tube gets broken, Results of the study has a certain role in field prevention and control of methane explosions and in reducing the hazard of methane explosions.
