Аннотация:Methods of evolutionary synthesis of integrated spectra of stellar clusters and galaxies are described. The model parameters are the initial chemical composition of stars, the slope of the initial mass function, the rate of star formation and the age of a system. The database for the evolutionary synthesis is a library of stellar spectra and evolutionary tracks of stars. The color (B-V) and equivalent widths of some hydrogen absorption lines, and metal lines and bands of the model spectra are the numerical characteristics of the model. Comparison of the model spectra with those of actual stellar clusters provides satisfactory results. Further calculations of integrated spectra of galaxies by the method of evolutionary synthesis with modification of all the parameters of the model are discussed.
