According to the distribution of surface density and the rotation curve in discoid galaxies with bulge, the steady hydrodynamic equations doubled with the Poission equation are numerically solved, from which the three-dimensional mass distribution and velocity distribution in discoid galaxies are obtained. The results show that the central spheroid of the discoid galaxy is a high density region. The stars and clusters in this region have the same dynamic characteristics as in the spheroidal galaxies. These results are consistent with observations.
