摘　　要：采用自洽平均值近似法和Hellmann-Fevnman(HF)定理求解定态含电子自旋轨道耦合项碱金属原子的本征能量,并将自洽平均值近似法推广到含1/r2微扰项的碱金属原子模型。由于电子自旋轨道耦合,原子的每一简并能级发生劈裂。By using the self-consistent average approximation method and Hellmann-Fevnman（HF）theorem, the eigenvalue of alkali metal atoms with electron spin-orbit coupling is given. The method is also applied to the alkali metal atoms model with the perturbation potential and spin-orbit coupling. It shows that due to the spin-orbit couping, every degenerate energy level is splited to two.
