摘　　要：采用全相对论量子力学GRASP2程序平均能级AL模型,考虑到核的有限体积效应、Breit和QED效应,系统地计算了金和铀的高剥离态的部分离子态的电离势,将所得的计算结果和文献报道的实验值进行比较。结果表明,考虑高剥离态原子的高阶修正后,高剥离态离子的电离势的计算值与实验数据之间的误差基本消除。Based on the relativistic quantum mechanics, the ionization potentials of highly charged gold and uranium ions have been calculated using the general-purpose relativistic atomic structure program (GRASP 2).The average level (AL) model, finite nuclear size, Breit and QED correction all are taken into account, and the obtained results are quite reasonable ,some of them are in agreement with the experiments data or reference data available.
