Abstract：
Pairing correlation strongly influences various nuclear properties, including the binding energy, low-lying excited spectrum, and angular momentum alignment of a rotational band etc. The systematically observed large fluctuation in odd-even differences of moments of inertia and their nonadditivity can't be accounted for by the traditional BCS method for treating nuclear pairing correlations, instead, can be explained satisfactorily by the Particle-number conserving method, in which blocking effect is treated strictly.
