摘要
根据细致组态方法，采用不分辨的跃迁矩阵模型（ＵＴＡ）在组态平均近似下可以容易地计算由高功率激光产生的局域热动平衡状态下的等离子体的不透明度。采用量子亏损理论计算在激光产生的中－Ｚ和高－Ｚ元素的等离子体中的高主量子数组态的ＵＴＡ参数，可节省了大量的计算时间，采用全相对论处理的方法可以快速地计算任何高Ｚ元素等离子体的不透明度。还可以很方便地确定最重要组态以及细致地分析跃迁矩阵。
Using the detailed configuration accounting with the term structures treated by the unresolved transition array model, we present a method to calculate the transmission spectra for high power laser produced plasmas in local thermodynamic equilibrium. Based on the quantum defect theory, the UTA parameters with high principal quantum numbers can be conveniently calculated with much less computational efforts. This ensure us to handle a huge number of transition arrays from many configurations occurring in typical laser produced middle Z and high Z plasmas.
