Abstract:We have computed a set of multiphase chemical evolution models in which the radial mass distributions of each theoretical galaxy is calculated using the universal rotation curve from Persic, Salucci and Steel (1996). We obtain the chemical evolution for galaxies of different masses and morphological types by changing the efficiencies to form molecular clouds and stars according with these types. We obtain the radial distributions of diffuse and molecular gas densities, the star formation rate and abundances for 15 elements for each galaxy.
