Abstract：
The construction of a paired state of a quantum many-particle system is closely connected with its symmetry. There are three types of construction of paired state in axially symmetric deformed nucleus, i. e., monopole pair, ±Ω pair and signature pair, which are the eigenstates of (J², J₃), J₃, and (J₃², R₁(π)), respectively.When only the pairing force is involved, the energy spectra of all three pairing Hamiltonian are identical. However, in the case of Cranked Shell Model, since the three types of paired states behave differently under space rotation, the energy spectra and the w variation of other relevant features differ to certain extent.
