When matter,especially high Z-element, is heated to high tempersture, it will be ionized many times. The degree of ionization has a strong effect on many plasma properties.So we need an approximate method to calculate mean ionization degree in many practical problems.In this paper, an analytical expression which is convenient for the approximate numerical calculation, is given by fitting it to the scaling law and numerical results of the ionization potential of Thomas-Fermi statistical model. In LTE case, the degree of ionization of Au calculated by the approximate method of Ref.(2) is in agreement with that of the averageion model. By extending the approximate method to Non-LTE case, the degree of ionization of Au is similarly calculated according to Corona model and Collision-Radiation model(C-R). The results of Corona model agree with the published data quite well, while the results of "C-R approach those of Corona model as the density is reduced and approach those of LTE as the density is increased. Finally, all approximately calculated results of ionization degree of Au and the comparision of them are given in figures and tables.

当物质被加热到高温时,特别是高Z元素都要产生多次电离。电离度对等离子体的很多性质都有重要影响。因此,为了解决等离子体的很多实际问题,需要寻求一种计算平均电离度的近似方法。在本文中,首先将文献[1]给出的Thomas-Fermi统计模型电离势的标度律和数值结果用函数逼近,给出了一个便于近似数值求解的解析表达式,然后利用文献[2]给出多次电离的近似计算方法,计算了Au元素LTE情况下的电离度,结果与平均离子模型的计算结果符合得很好。另外,我们将近似方法推广到non-LTE情况,根据电晕模型和碰撞-辐射模型对Au的电离度作了类似的计算。电晕模型的计算结果与文献[1]发表的数据符合得十分好;而碰撞-辐射模型的计算结果随着密度的降低趋近电晕模型的结果,而随着密度的升高趋近于LTE的结果。最后以图表的形式给出了Au元素电离度的所有计算结果及其比较。

The relative intensity radios for the production of one K-shell and multiple L-shell vacancies are measured. The average ionization probabilities PL(Ei,0) are compared with the predications of the binary-encounter approximation (BEA) for mutiple ionization.
