摘要
从磁流体动力学方程组出发，用微扰法得出吸积盘径向振荡超稳定性的色散方程，并在７种情况下详细讨论了磁场、径向粘滞力和修正的α型粘滞对吸积盘不稳定性的影响．得出的结论为解释活动天体的光变现象提供了进一步的理论根据．
The dispersion equations involing the overstability of axisymmetric oscillation are derived by using MHD equations for the Perturbations.The affections on the instabilitiot Of accretion disks by the magnetic fields,the radial viscous force and the modified α-type viscidity are investigated in details In seven cases.These results provide the further theoretical basis for explaining the optical variability of active astronomical objects.
