摘要：

We obtained global transonic solutions representing optically thin advection-dominated accretion how by solving the full set of differential equations describing such systems. We found that far from the sonic point self-similar solutions are an excellent approximation of the global how structure if the accretion rate is well below the maximum value above which no optically thin solutions exist.
