Abstract：
The particle-number-conserving approach for treating nuclear pairing correlation is extended to treat the eigenvalue problem of the cranking hamiltonian.Detailed information about the seniority structure and the K-structure of the low-lying bands,and their spin alignments,signature splittings,and pair-transfer matrix elements can be provided in this formalism.
