Abstract：
With increasing the rotational frequency ω,the seniority V-structure and the K-structure of the CSM wave function become very complicated.For not too high ω(hω≤0.5MeV) configurations with V=0,2,4 are dominant for the low-lying bands,while those with V≥6 are negligibly small.Configurations with various K-values (│K│≤10) are comparable and the nucleus deviates from axial-symmetry significanly.The variation of the gap parameter with ω are analysed also.
