Scientific paper

The main results of a study of a catalogue of physical parameters of 1041 spectroscopic binaries are presented. The results of the analysis of the observed distributions of SB's over the main, genetically and evolutionary stipulated parameters, such as apparent brightness and orbital periods, are given. The main effects of observational selection that prevent the direct analysis of innate distributions of SB's over masses, mass ratios of components, and the large semiaxes of their orbits are briefly discussed. Models of observed distributions of bright SB's over M(1), M(2)/M(1) and the large semiaxes are computed by a program which, starting with arbitrary distributions, generates models of observed distributions, taking into account the important effects of observational selection and stellar evolution.
