EFFECTS OF DIELECTRONIC RECOMBINATION ON ELECTRON OCCUPATION NUMBER FOR NON LTE SYSTEM
-
摘要: 在求解平均原子中各能级的电子占据几率的速率方程时, 加入了双电子复合效应的影响。以Al 等离子体为例, 在不同温度密度条件下, 通过大量的数据计算, 分析了双电子复合对电子占据数的影响, 给出了双电子复合影响较大的温度密度区域。并对Au 等离子体进行了计算, 发现双电子复合对其电离度影响很大。Abstract: Dielectronic Recombination(DR) has been included in the solution of the rate equations in the average atom(AA) model. Employing the method proposed by Zao Libo and Li Shichang the DR rate coefficients was calculated. The results show that DR plays an important role in some cases in Al plasma and the average degree of ionization for Au plasma is sharply decreased after considering DR process.
