用全实加关联方法计算了类铍体系的1s2 2s2基态能量。采用部分饱和基函数法外推较好的非相对论能量。考虑相对论修正、质量极化和QED效应，计算了1s2 2s2电离势.这些结果与文献中现有的理论和实验数据进行了比较。预测的Be I、C III、N IV和0V电离势在引用的实验误差范围内
The 1s 2 2s 2 ground-state energies of berylliumlike systems are calculated with a full-core plus correlation method. A partial saturation of a basis-function method is used to extrapolate a better nonrelativistic energy. The 1s 2 2s 2 ionization potentials are calculated by including the relativistic corrections, mass polarization, and QED effects. These results are compared with the existing theoretical and experimental data in the literature. The predicted Be I, C III, N IV, and 0 V ionization potentials are within the quoted experimental error
