摘要
爆轰波穿越惰性气团再进入可燃混合气体时,透射激波的参数主要受到三个基本过程的影响:头激波两次穿越惰性气团与可燃气体之间接触面导致的激波强度下降、放热反应中止、爆轰波后稀疏波对激波的衰减作用。放热反应中止是透射激波衰减的主要原因,不同种类的惰性气体对透射激波参数影响不大。
When detonation transmits an inert gas zone and re-enters combustible gas mixture, the shock parameters are affected by the following mechanisms： interactions of shock and the two contact surfaces between combustible gas mixture and inert gas ; the termination of chemical reaction heat releasing, shock decay in inert gas by the rarefaction waves behind detonation wave. The termination of heat releasing is the main cause which decreases of Mach number of transmit shock ; using different kind of inert gas has little effect on transmitting shock.
