摘要
The stability of an isothermal thin disk with three-dimensionalmagnetic fields and radial viscosity force is examined in this paper. We findthat the radial viscous force has no influence on stability of viscous modes. Butthere are more influence on the stability of magneto-acoustic modes, which isrelated to the perturbation wavelenth and different parts of disc .Finally, weuse our model to explain the long term variability of Quasar 3C345.
