摘要: 基于含温有界相对论自洽场平均原子模型，计算了高温稠密条件下气态混合物的压强。通过求解相对论Dirac方程给出有界原子的电子波函数和轨道能量。电子在各单电子轨道上的平均占据数服从Fermi-Dirac分布。以铝、铝镁混合物、铁和高能炸药HMX（奥克托金）为算例，计算了在一些温度密度点下的压强并给出了分析。Abstract: Based on the relativistic self-consistent average atom model, the orbital energies and wavefunctions for the bound electrons are calculated by solving the Dirac equations. The average occupation numbers at each orbital and the average ionization degree of each kind of atom are determined by the Fermi-Dirac distribution. The pressure of hot and dense gas mixtures is presented in terms of a quantum free electron gas, a quantum photon gas, and a classical ion gas. The pressure of Al, the mixture of Al and Mg, Fe, and the explosive HMX are calculated at certain temperatures and densities.
