    考虑到爆轰波阵面曲率及化学反应区宽度的作用，由修正Hugoniot关系式解析求解了波后状态，应用阵面追踪法(FTM)数值模拟了曲面散心爆轰波的传播。计算给出的散心爆轰波走时及波阵面上物理量都达到了波阵面曲率的一阶精度。

    Considering the curvature and width of reaction zones,FTM(FrontTracking Method)was used to study the propagation of diverging detonation waves.The parameters behind wave fronts were from modified Hugoniot relationships by neglecting narrow reaction zones. Numerical results indicate that time histories as well as parameters at wave fronts are in the first order of front curvature κ.
