摘要：

利用l分裂的屏蔽氢不透明度模型计算了Ar、Kr、Xe惰性元素混合物随光子能量变化的不透明度以及Rosseland平均不透明度。研究了温度为100~250 eV, 密度为0.5~2 g•cm⁻³范围内惰性元素混合物的Rosseland平均不透明度与混合物质、混合比例、温度和密度的密切关系。结果显示，Ar-Xe混合以及Xe-Kr混合后的Rosseland平均不透明度比它们为纯元素时有较大的增加；而Ar-Kr混合后的Rosseland平均不透明度则比纯Kr低。通过对比纯惰性元素随光子能量变化的不透明度峰、谷值，分析了造成混合后不透明度增加或降低的原因，同时给出了获得惰性元素混合物平均不透明度为最大时的混合比例。

Abstract:

The frequency-dependent opacities and the Rosseland mean opacity for mixture of inertia elements Ar, Kr, Xe are studied using the l splitting screened hydrogenic model. The relation of the Rosseland mean opacity for inertia elements mixture to the mixture specifications, mixed proportion in densety range of 0.5~2g·cm⁻³ and temperature range of 100~250eV are investigated. The results indicate that Rosseland mean opacity is enhanced significantly for mixture of Xe-Ar and Xe-Kr but not increased for mixture of Ar-Kr. The comparison of the frequency-dependent opacities of pure inertia element absorption peaks and valleys, we account the reason for enhancement or reduction in the Rosseland mean opacity for mixed inertia elements, and the optimal mixed proportion to obtain the maximal mean opacity for inertia element mixture.
