| 摘 要： | 基于能级均匀分布的理想模型,分别用SLAP和BCS方法处理对关联,计算体系的总能量、对能、单粒子能量及其占据几率,展示总能量、对能和单粒子能量随对力强度因子变化的情况,比较SLAP和BCS方法计算结果的差异.研究表明:BCS方法能够明显地反映从超流态到正常态的相变,SLAP方法更适合描述与粒子数关系明显的物理量.

| Abstract: | The shell‐model‐like approach (SLAP) and BCS methods were used to treat the pairing correlations for an ideal model .The total energy ,pairing energy ,particle energy and particle occupation together with their evolutions with the pairing strength were obtained . The research indicated that the phase transition from the super fluid to the normal reflected by BCS was clearer ,but SLAP might be more reasonable method for describing physics parameters w hich had obvious relations with the particle number . |
