We modify the viscosity to disappear inside the sonic point in the advection-dominated accretion flows (ADAF's) around black holes, and obtain the causally connected, physically self-consistent ADAF-thin disk solutions. Such global solutions differ from previous ones in quantitative details. The results show that the range of variation for the value of the outer boundary R<sub>out</sub> is very large, from 30R<sub>g</sub> to 10<sup>6</sup>R<sub>g</sub>. There is a narrow region for which the rotating motion of the flow is super-Keplerian in each global solution. An example global solution with the causal viscosity is given explicitly, for which R<sub>s</sub> = 2.28R<sub>g</sub> and j = 1.7564(cR<sub>g</sub>). |
