The radial oscillation instability of both the magneto-equipartition model and the magneto-conservation model of accretion disks with self-gravitation is examined. The authors' results show that there are three modes in the disk. The viscous mode is always stable, the magneto-acoustic one is unstable and the neutral one tends to be stable in the long wavelength region, but unstable in the short wavelength region. Meanwhile, the effects of self-gravitation for the three modes are similar in both models, but the effects of the magnetic field are opposite. These results imply that the magneto-equipartition model is the best one for explaining the time variations of X-ray stars and AGNs.
