摘　　要：运用化学流体力学基本理论 ,建立了一维激波诱导可燃气体爆燃的九化学反应模型 ,完成了CO气体爆燃过程的数值模拟 ,由CO气体密度的变化以及流场中压力和温度的相应变化 。Based on the theory of reaction fluid dynamic, numerical simulate about the process that shock waves induce the combustible gas deflagrating in one-dimensional system with the chemical model of nine equation is successfully accomplished. The generation mechanism of the induced process and an important effect of shock waves extinguishing the forest fire are clearly interpreted by the density variety of CO and the variety of pressure and temperature in the field.
