摘要： 波函数中固有的节点表面在四价电子原子的壳内态中已被研究。这些表面的决定性作用已被证明，低能级的排列顺序已被预测，一个主要的分类方案已被提出，三个旋转带的存在已被建议。 显示英文摘要

摘要： Inherent nodal surfaces existing in the wavefunctions of intrashell states of 4-valence-electron atoms have been investigated. The decisive effect of these surfaces has been demonstrated, the ordering of low-lying levels has been predicted, a primary classification scheme has been proposed, the existence of three rotation bands has been suggested.
