用处理对力的粒子数守恒方法分析了A～190区偶偶核系列晕SD带192—198Pb(1)和198Po(1)的转动惯量随角频率变化的规律. 计算中同时考虑了单极对力与Y20四极对力. 实验结果在计算中得到较好的重视. 特别是转动惯量变化的微观机制(包括中子和质子的各大壳以及各单粒子能级的贡献)在计算中得到极为清楚的展现. J(2)的上升，主要来自高N闯入壳(中子N=7,质子N=6)的贡献，而其它大壳对J(2)的贡献，基本上不随ω而变化.

The variations in moments of inertia (J(2) and J(1)) with rotational frequency for the series of yrast SD bands in even-even nuclei, 192—198　　　Pb(1) and 198　Po(1), are investigated by using the particle-number conserving method for treating the pairing interaction (monopole and quadrupole). The observed ω variations of J(2) and J(1) are reproduced quite well in the PNC calculation, particularly the microscopic mechanism (the contributions from each major shell and each cranked Nilsson orbital) is clearly displayed. It is found that the smooth rise of J(2) with ω is attributed to the contribution from the intruder shells (neutron N=7 and proton N=6).
