非平衡Al等离子体三温自由程的数值模拟

NUMERICAL SIMULATION OF THE THREE TEMPERATURE FREE PATH FOR NON LTE Al PLASMA

在非平衡系统中，采用三温（光子温度ｔγ，电子温度ｔｅ和离子温度ｔｉ）模型来计算光子能流的自由程；通过解速率方程得到电子的占据几率Ｐｉ，讨论了它与用ＦｅｍｉＤｉｒａｃ分布函数算得的ｎｆ之间的差别；给出了Ａｌ等离子体三温自由程的数值模拟结果。

The mean free path for photon energy flux is calculated with the three temparature model in the NON LTE system;The electron occupation probabilities P i are obtained by solving the rate equations;The results of numerical simulation for aluminum plasma are given with comparision and discussion.
