摘　　要：设想把原子核看成由α-结团,pn对,nn对组成,发现pn对、nn对和α-结团之间的相互作用造成了在奇异核中分离nn对时所需的分离能的有规律变化.这种有规律的变化表现为在轻核的奇异核中分离nn对时所需的分离能一高一低的变化,这种现象有更深的物理意义.It was supposed that, the nucleus was composed of α - cluster, pn - pair, and nn - pair. The reciprocity of the α - cluster, pn - pair, and nn - pair caused the disciplinary change of the separating energy to separate the nn -pair in the exotic nuclei. The disliplinary change was that the separating energy was high bebind low to separate the nn - pair in the light and exotic nuclei. This phenomena must had more profound physical meaning.
