摘 要: | 用标准的龙格-库塔法求解描述黑洞吸积流的基本方程组,没有引入任何附加的能量转移机制和外边界条件,结果表明在强粘滞情况下标准薄盘可以向径移主导吸积流转变。

Abstract: | Using the standard Runge-Kutta method, a set of basic equations describing black hole accretion flows is solved. The results show that a transition from a standard thin disk to an advection-dominated accretion flow is realizable for the high-viscosity case, without involving any extra mechanism of energy transport or specifying any ad hoc outer boundary condition. |
