Аннотация:We solve the vertical structure equations for a standard α -disk and compare the results with those obtained by an independent method (Ketsaris \amp Shakura 1998). On the basis of the numerical solutions for the vertical structure we obtain analytic radial dependences for the physical parameters of the disk. For a disk consisting of fully ionized hydrogen, its half-thickness is about 2.5 times larger than that obtained by the “standard” solution, averaging the vertical structure equations. Account of heavy elements leads to an additional increase of the half-thickness by approximately 25%.
