摘要: 本文用平均原子模型，对热稠密物质U92的状态方程，进行了Hartree-Fock-Slater计算。以Zink解析拟合势作为初始势及孤立原子的TF能级作为初始能级，求解满足Wigner-Seitz边界条件的Dirac-Slater方程。通过简并度是密度的连续函数来考虑大密度时的压致电离效应。

Abstract: Within the approximations of spherical lattice cell, central-field and relativistic Fermi statistics, an average atom model is presented to calculated the electronic energy levels and equation of state for hot and dense U92. Zink's analytic potential is chosen as starting potential to solve Dirac-Slater equation satisfying the Weifnei-Seitz boundary condition. The electronic energy bands are not taken into account. The pressure ionization effects are included by level degeneracy as a continuous function of matter densities of U92. -
