摘要：

The standard thin disk model predicts that when the accretion rate is moderately high, the disk is radiation-pressure-dominated and thermally unstable. However, observations indicate the opposite, namely the disk is quite stable. We present an explanation in this work by taking into account the role of the magnetic field which was ignored in the previous analysis.
