Abstract：
The intrinsic structure of the eigenfunctions of Cranking Shell Model Hamiltonian and the pairing phase transition at high rotational frequency are investigated with the particle-number-conserving approach. Pair-transfer matrix elements and the K-stojcture of the wave functions display similar behaviour under the Coriolis interaction, hence, both of them may be used to indicate the pairing phase transition. The blocking effects on pairing parameter, △ = G√< S + S >, are much more important than the Coriolis anti-pairing effects.
