ABSTRACT The pair correlation function (PCF) in a non-degenerated plasma, containing multi-species of electric charges (electrons, positive and negative ions and impurities) are calculated in a Multi-Component Plasma (MCP) model. The method stands on the use of the statistical mechanics under the mean-field theory approach where the screening and the quantum effects have been taken into account. The coupled system of the obtained nonlinear integral equations (NIES) governing the pair correlation functions are solved numerically in three-dimensional space with three different methods: Fixed Point Method (FPM), Verlet Method (VM) and Finite Difference Method (FDM). These methods generally give the same results which are in a good agreement with those obtained by the molecular dynamics simulation (MD).

多组分等离子体的对相关函数：理论和数值

摘要 在多组分等离子体 (MCP) 模型中计算了包含多种电荷（电子、正负离子和杂质）的非简并等离子体中的对相关函数 (PCF)。该方法基于在平均场理论方法下使用统计力学，其中考虑了屏蔽和量子效应。所获得的非线性积分方程 (NIES) 的耦合系统控制对相关函数在三维空间中使用三种不同的方法进行数值求解：不动点法 (FPM)、Verlet 法 (VM) 和有限差分法 (FDM)。这些方法通常给出相同的结果，这些结果与通过分子动力学模拟 (MD) 获得的结果非常一致。
