在轴对称、几何薄、光学厚吸积盘模型的基础上，应用新的粘滞定律（磁粘滞为主）以避免标准吸积盘内区的热不稳定及粘滞不稳定定。考虑了自引力的作用，计算出了稳定的磁粘滞自引力薄吸积盘外区的结构，综合盘外区的结构，讨论了吸积盘外区的辐射性质以及发射线的有关问题．
Based on the model of axisymmetric, geometrically thin and optically thick accretion disk, a new viscous law (mainly magnetic) is applied to avoid thermal instability and viscous instability in the area of standard accretion disk. Taking into account the role of self-gravitation, the structure of stable outer area of magnetically-viscous self-gravitation thin accretion disk was calculated. Based on the structure of the outer disk area, the radiation properties of the outer area of the accretion disk and the related problems of the emission line were discussed.
