| 摘 要： | 基于含温有界相对论Dirac自洽场原子模型,采用电子-离子散射机制,在Born近似下,计算了部分离化等离子体物质的电子传导不透明度(Electron Conductive Opacity)。以铯(Cs)为例,同他人结果作了比较,给出钛(Ti)元素温度kT=10～10~3eV,密度ρ=0.1ρ_0～10ρ_0范围的电子传导不透明度K_C。

| Abstract: | On the basis of a relativistic self-consistent temperature and density-dependent Hartree-Slater "average atom" model, the error of electron conductive opacities by approximating the self-consistent electron-ion potential with two superimposed Yukawa potentials was checked. The electron conductive opacities for titanium are given by the direct numerical integral at temperatures ranging from 10eV to 103eV and for densities from 0.1 p0 to 10/7n(p0 = 3.988g/cm3). |
