摘　　要：采用一维流体动力学模型，以烧蚀压力作为已知的边界条件，分别以解析和数值计算方法，描述了短脉冲强激光辐照固态铝、铜和碳酚醛靶材时，烧蚀加载在靶材中产生的激波的增强、持续和衰减过程，给出了激波峰值压力和波形等特征参数的时空关系。A numerical method and an analytical method for study creation and decay of laser generated shock wave in the target are presented on the basis of one dimensional hydrodynamic model. The ablation presure is used as boundary condition. These methods permit the caculation of the three stages of shock wave evolution. Three kinds of solid state material, such as Al, Cu and C/Ph are caculated.The maximum presure and shock wave profile of each material are given out.
