By analyzing the coupling between magnetic fields and accretion flows we get following results:(1) There should be an upper limit to the magnitude of magnetic field. Under such a case the disk remains Keplerian.(2) The observational distribution of effective temperature might be caused by magnetic diffusion.

对于磁化薄盘，我们的结果归纳起来是二点：(1)磁化薄盘应该有一个上限磁场，在这样的情形之下，磁化盘保持为开普勒盘；(2)观测上的有效温度的分布可能就是由于磁能的耗散而产生。

By analyzing numerically the disks around a young stellar object and a black hole, we can obtain: the dissipation can not be neglected as a magnetic field is in small threshold value; in Keplerian disks, the magnetic field is smaller, the dissipation caused by anomalous viscosity and anomalous resistivity deviates from the ideal more greatly; the dissipative effects on magnetic instability become smaller as the radius r becomes larger.

通过分析年轻恒星周围和黑洞周围吸积盘的数值解可以得到：在磁场比较小的一段阈值内，这种耗散过程是不可忽略的；而且，磁场越小，由反常黏滞及反常阻抗引起的耗散过程对磁不稳定性的影响就越大；离中心体的距离r越大，耗散过程对磁不稳定性的影响越小。
