| 摘 要： | 数值计算了激光直接驱动铝飞片空腔靶模型.结果表明：激光和靶结构参数对飞片状态和靶中冲击波特性的影响很大；如果激光和靶结构参数选择合理的话，可以近似实现飞片与靶的对称碰撞，而且靶中冲击波的稳定区有一定的空间宽度；因而，选择适当厚度的三台阶靶，可以近似实现状态方程的绝对测量.

| Abstract: | We present the numerical calculation of the model of aluminum flyer-vacuum-target with high power laser driving.The results show that the parameters of laser and target's structure have great effects on the state of flyer and the character of shock-waves in the target.If we select the parameters of laser and target's structure reasonably, we can achieve approximately symmetric impact between flyer and target;moreover,the shock-wave in the target has a stable area with a certain spatial width.So,if we choose the three-step-target with a suitable thickness,we can approach an absolute measurement of equation-of-state. |
