本文用少体方法对Ａ≤４的Ｓ壳超核动力学结构进行系统研究，同时研究Ａ≤３的普通原子核的结构，通过比较，看到了超子进入核内使结构产生变化，超子的加入，造成壳心核的缩聚，核子间均方根距离缩短，超子在核内起胶粘凝聚作用。对这些核体系内部结构的研究表明．粒子间相对运动主要处于Ｏｓ轨道。 In this paper, we systematically studied the kinetic structure of the S-shell hyperonuclear nuclei with A≤4 by means of the small-body method and studied the structure of ordinary nuclei with A≤3. By comparison, we can see that the hyperon enters into the nucleus to make the structure change, Join, resulting in shell core nucleus polycondensation, shortening the distance between the nuclei root mean square, super cohesion in the nucleus from the cohesion. Studies of the internal structure of these nuclear systems have shown. The relative movement between particles is mainly in the Os orbit.
