The pairing correlations decrease with increasing temperature. However, in some nuclei, the pairing effect is strongly enhanced at a certain interval of temperature. This phenomenon was called pairing reentrance. In this work, we study some testing configurations of nuclear single-particle levels, which can produce this reentrance. The results show that the configurations with an odd nucleon number obtain the pairing reentrance effect. This effect will be suspended by decreasing the single-particle energy gap of the two levels nearest the Fermi surface. The calculations for realistic candidate Calcium isotopes also confirm this phenomenon.
