J., Jr. ; Arnett, W. D. Abstract Computations are made of the structure and evolution of models of the disk component of galaxies. The models display the qualitative characteristics and the statistically dominant trends observed in late-type spirals. The radial distributions of neutral hydrogen, of H II regions, and of colors are well reproduced. Composition gradients are found across the faces of disk models. Using the observed supernova rates in spirals, these models place fairly severe constraints upon the progenitors of supernova. If azimuthally averaged, high-resolution observations of neutral hydrogen will provide interesting quantitative tests of models of this type. Equations governing the structure and evolution of the present models of the disk components are discussed in detail, as are the uncertainties in input physics and astronomy.
