本文采用二阶精度迎风ＴＶＤ格式对轴对称的激光等离子体流进行了数值计算，模拟研究了Ｎｄ：ＹＡＧ高功率脉冲激光与铝靶相互作用时等离子体场的形成过程，获得了与实验结果一致的时间相关解。
In this paper, the second-order precision windward TVD format is used to calculate the axisymmetric laser plasma flow. The formation process of plasma field in Nd: YAG high-power pulsed laser interacting with aluminum target is simulated. The experimental results are consistent with the experimental results Time correlation solution.
