摘　　要：在相对论平均场理论框架下,首先证明了对力强度存在明显的壳效应,然后用此方法研究了 Z=96-102区域内超重同位素链中中子壳封闭问题,证明了在超重元素中,N=184处确实存在壳封闭．并据此给出了一种检验壳封闭的新方法．The clear shell effect of the pairing strength is proved based on the frame of the relativistic mean filed theory. With the same theory, the closed shell problem of the superheavy isotope chain around Z = 96-102 is studied. The results show that N = 184 for neutron is a closed shell. According to the study, a new method to check the shell closure is given.

关 键 词：相对论平均场理论 壳闭合 对力强度
