提出了在现象学和半微观水平上描述核子类壳四分位的代数模型。在前者看来，四重奏是一个无结构的对象，而在后一种观点中，四重奏的组成部分则被明确地对待。在这两种情况下，激发谱都由SU(3)形式生成。给出了一个应用于20ne核的例子。
Algebraic models are proposed for the description of the shell-like quarteting of the nucleons both on the phenomenologic and on the semimicroscopic levels. In the former one the quartet is considered as a structureless object, while in the latter one its constituents are treated explicitly. The excitation spectrum is generated by the SU (3) formalism in both cases. An application to the 20 Ne nucleus is presented.
