%X 在微扰论的基础上引入屏蔽参数a，建立含有屏蔽参数a的氦离子N5和O6+哈密顿方程。以有效核电荷数为z*=z-a的类氢原子基态1s和激发态ns(n=1,2,…)组合的双电子波函数，作为氦离子N5和O6+的基态近似波函数。根据类氦离子N5和O6+的基态能量的实验值，通过求极值的方法确定合适的屏蔽参数a，由此计算类氦离子N5和O6+的基态能量。结果表明，应用参数微扰法计算类氦离子N5和O6+基态能量的理论值与实验值的误差为10E-4~10E-5。<br>Hamilton equation of the helium-like ion N5+ and O6+ including shielding effect parameters a was established on the basis of the perturbation theory. A combination of the ground state 1s and the excited state ns(n=1,2,…) wave functions of two hydrogen-like atom as the two electrons’ wave function with effective nuclear charge number of was chosen as the ground state approximate wave functions of the helium-like ion N5+ and O6+. The ground state energy of the helium-like ion N5+ and O6+ was calculated by the appropriate shielding parameters a that was determined with the method of extreme value according to the experimental value of the ground state energy of helium-like ion N5+ and O6+.Calculation results show that the error of the energy of the helium-like ion N5+ and O6+ ground state with perturbation method is 10E-4~10E-5 compared with the experiment results
