Based on the hydrodynamic equations of the accretion disks, the conservation equations of mass, momentum and energy with absence of magnetic field was given. On the basis of the equations obtained, the structure of the inner region of the accretion disks surrounding black hole was calculated by using the new anomalous viscosity. The numerical results showed that the gas motion was not Keplerian in the inner region of the disk. The temperature varied significantly with the accretion rate, the maximal temperature of the accretion disks could reach 3.35×107K in the case of M=10M,M .=100M .E. The distributions of the mass density and the radial velocity were also shown in this paper.

Key words: black hole; accretion disks; anomalous viscosity; accretion rate
