摘要
根据雪崩电离、逆轫致吸收、Saha方程和等离子体状态方程等实现了用迎风TVD格式对空气的击穿过程进行了数值模拟，结合光学击穿和激光感应热击穿理论，研究了Nd：YAG高功率脉冲激光与空气相互作用时，等离子体场的形成过程，得到了激光等离子体流场的非定常解。
In this paper second order accurate upwind schemes in total variation diminishing (TVD) type are employed for numerically calculating axisymmetic laser-induced-air plasma field and simulating forming process of laser-induced plasma field as high-power YAG laser interacts with air. A time-dependent solution which accords with experimental result has been obtained.
