摘要 针对非轴对称的吸积盘中压力主要为辐射压的区域,采用一种新的黏滞机制(反常磁黏滞),利用数值方法进行了吸积盘的不稳定性分析。结果表明,随着方位角扰动波数的增大,热模越来越不稳定;黏滞模、In-模和Out-模越来越稳定。并且,吸积盘所采用的黏滞机制对不稳定性结果有着重大影响。 The non-axisymmetric instability of the radiation-pressure-dominated accretion disk is solved by numerical simulations where we adopt a new viscosity prescription(i.e.anomalous-viscosity).The result is that the thermal mode becomes more unstable,while viscous mode,I-mode and O-mode become more stable with the increase of the azimuthal perturbation wave number n.The results are very different in the different viscosity prescriptions.
