摘要
We take the vertical distribution of the radial and azimuthal velocities into account in spherical coordinates, and find that the analytic relation c(s0)/v(K)Theta = [(gamma-1)/2 gamma](1/2) is valid for both geometrically thin and thick accretion flows, where c(s0) is the sound speed on the equatorial plane, v(K) is the Keplerian velocity, Theta is the half-opening angle of the flow, and gamma is the adiabatic index.
