用粒子数守恒(PNC)方法研究了正常形变和超形变原子核的配对能隙，该模型精确地处理了阻塞效应。研究了TERDE的配对能隙(Delta)随转动频率欧米伽的变化以及随时间的变化(未成对粒子数)。对于偶偶核的基态带，PNC计算表明，一般情况下，(Delta)Over Tide随omega的增加而减小，但omega的依赖性比用数投影的Hartree-Fock-Bogolyubov方法计算的要弱得多。对于多准粒子带(资历nu>；2)，配对能隙几乎保持欧米伽无关。作为资历nu的函数，随着nu的增加，波纹波(nu，omega=0)上的带头配对间隙(Delta)缓慢减小。即使对于到目前为止识别的最高资历nu频段，(Delta)相对于波浪线(nu，omega=0)仍然大于波浪线(nu=0，omega=0)的(Delta)的70%。
Nuclear pairing gaps of normally deformed and superdeformed nuclei are investigated using the particle-number-conserving (PNC) formalism for the cranked shell model, in which the blocking effects are treated exactly. Both rotational frequency omega dependence and seniority (number of unpaired particles) nu dependence of the pairing gap (Delta) over tilde are investigated. For the ground-state bands of even-even nuclei, PNC calculations show that, in general, (Delta) over tilde decreases with increasing omega, but the omega dependence is much weaker than that calculated by the number-projected Hartree-Fock-Bogolyubov approach. For the multiquasiparticle bands (seniority nu > 2), the pairing gaps stay almost omega independent. As a function of the seniority nu, the bandhead pairing gaps (Delta) over tilde(nu, omega = 0) decrease slowly with increasing nu. Even for the highest seniority nu bands identified so far, (Delta) over tilde(nu, omega = 0) remains greater than 70% of (Delta) over tilde(nu = 0, omega = 0).
