| 摘 要： | 在新的反常黏滞机制的基础上,利用微扰方法导出色散方程,分析了耗散过程对吸积盘磁不稳定性的影响。 结果表明:耗散率随半径的增大而减小;在磁场较小时,耗散过程的影响不可忽略。这不同于在微观黏滞和阻抗基础上得到的结论。

| Abstract: | On the basis of the new model of anomalous viscosity,a dispersion equation was derived from the perturbation method,and the effect of dissipation on magnetic instability of accretion disks was analyzed.It was shown that the dissipative rate becomes smaller as the radius becomes larger and the dissipation can not be neglected as the magnetic field is smaller,which is different from the result derived from the microscopic viscosity and resistivity. |
