摘　　要：利用反常粘滞[1]研究了黑洞周围薄吸积盘的静态垂向结构.数值模拟得到了垂向结构上压力,温度,径向能流,物质密度和不同粘滞下径向速度的分布,发现考虑反常粘滞使各个物理量的分布更接近实际情况.The stationary vertical structure of a thin disk around a black hole is considered with the anomalous magnetic viscosity. These stationary vertical structures, including distributions of the pressure, temperature, radiative energy flux, mass density and radial velocities with different viscosities , are numerically examined. It is shown that the consideration of anomalous viscosity is necessary as all the physical variables are more close to the real conditions.
