Popis: We investigate the difference between the accretion disk models based on two kinds of α-prescription of viscosity. The models are constructed with self-gravity in the vertical direction of the disk around a supermassive black hole. It is found that the structures are completely different in the self-gravity dominant region, though they are almost the same for the standard disk model. We should be careful in treating viscosity, if self-gravity is taken into account for a disk model of an emitting region of H2O masers in an active galactic nucleus(AGN).
