We investigated the thermally unstable accretion disks around spinning black holes with different spins. Our code is a time-dependent 1.5-dimensional relativistic program. We adopted a new type of viscosity prescription according to results of some MHD simulaitions and we found some interesting high frequency ocsillation, whose fundamental frequency is identical to the prediction of trapped p-mode in QPO theory, during the outburst state of accretion disks.
