摘　　要：用平均原子自洽势计算等离子体的自由电子背景 ,通过在Hartree Fock Slater自洽场原子结构中引入背景修正计算离子组态结构 ,为Boltzmann Saha方程提供能级参数 ,再通过调节共同的背景电子实现Saha方程与Hartree Fock Slater方程的耦合 ,自洽求解等离子体细致组态原子结构 ,提高Saha方程的计算精度 .以碳、铝等离子体作为算例 ,分析了本方法的适用范围 .The effect of the free electron background in plasmas is introduced in Hartree-Fock-Slater self-consistent field atomic model to correct the single electron energies for each electron configuration, and to provide accurate atomic data for Boltzmann-Saha equation. In the iteration process chemical potential is adjusted to change the free electron background to satisfy simultaneously the conservation of the free electrons in Saha equation as well as in Hartree-Fock-Slater self-consistent field atomic model. As examples the equations of state of the carbon and aluminum plasmas are calculated to show the applicability of this method.
