摘要: 采用Thomas Fermi(TF)方法,计算了氢的高密度等离子体物态方程,并引入TF等效电离度概念。等效电离度的计算结果表明,TF方法也可用于宽广温度、密度范围的等离子体物态方程计算,且在高密度区,其结果比活度展开法(ACTEX)和Debye-Huckel(DH)理论更为合理。Abstract: The equations of state were calculated with Thomas-Fermi (TF) method and TF equivalent ionicity was introduced for the plasma hydrogen. The calculated results of the equivalent ionicity indicated that TF method can be used in wide range of the temperature (T) and density (), and is more reasonable than ACTEX and DH methods at high density.
