Abstract:
From the viewpoint of screen effect, penetration effect and polarization effect, the potential function of the Weakest Bound Electron Potential Model theory (abbreviated as WBEPM theory) is discussed. After deducing, the physical meaning of the effective potential suggested ithe theory is concluded that the first term in the potential function is the potential felt by thweakest bound electron in the central field of effective nuclear charge +Z′e, and the second term is the potential felt by the weakest bound electron in the dipole field produced by the polarizatio of the core composed of non-weakest bound electrons and nucleus.
Key words:  Weakest bound electron potential model theory, Effective potential, Screen effect Penetration effect, Polarization effect

摘要:
从屏蔽、贯穿和极化作用考虑,对最弱受约束电子势模型理论(简称WBEPM理论)的势函数进行了讨论.通过一系列推导、论证,得出WBEPM理论的有效势的物理意义为:势函数中的第一项表示最弱受约束电子在有效核电荷+Z'e中心场中的势能;第二项代表最弱受约束电子对非最弱受约束电子和核组成的"实”的极化作用所引起的偶极子场中的势能.
