对自引力磁均分和磁守恒两种模型的径向振荡稳定性的研究表明：在同时考虑自引力和磁场作用的情况下，吸积盘在磁均分和磁守恒模型中均存在着三种振荡模式，其中粘滞模式总是稳定的，磁声模式是不稳定的，中性模式在图中较长波段范围趋于稳定，在较短波段范围是不稳定的．这些结果有利于解释活动天体的Mark421和Pks2155—304的长周期光变现象．同时阐明了自引力在两种模型中对三种模式的影响有相同的趋势，而对磁场则分别起着相反的作用．这个结论表明磁均分吸积盘模型在解释光变现象时更为有利．
The research on the radial oscillation stability of the self-gravitation magnetic and magnetic models shows that there are three kinds of magnetization equalization and magnetic conservation models in both the self-induced and the magnetic field, Oscillation modes, in which the viscous mode is always stable, the magnetoacoustic mode is unstable, the neutral mode tends to be stable over the longer range of the graph, and unstable over the shorter range of the band. These results are helpful to explain the long-period photoluminescence phenomenon of Mark421 and Pks2155-304 in active celestial bodies. At the same time, it is clarified that the self-gravitation has the same trend of influence on the three modes in the two models, and the opposite effects on the magnetic field. This conclusion shows that the magnetic disk model of accretion disk is more advantageous in explaining the phenomenon of light change.
