摘要
In this paper, we study the relativistic, steady state, optically thin, advection-dominated accretion disks around the rotating black holes. We study axisymmetric and vertically averaged disks. For shear stress viscosity, the exact relations of the four-velocity with no approximation are derived. We effort to derive the general and analytic relation for density, relativistic enthalpy, temperature, pressure and inertial energy. We use the radial model for the radial component of four-velocity. In the radial model, the figures of density etc. are plotted. The influences of shear and bulk coefficients and spin of the black hole etc. are studied.
