  In this paper, we investigate the orbital and stellar parameters of low- and
intermediate-mass close binary systems. We use models, presented in the
catalogue of (Han et al. 2000) and calculate parameters of accretors. We also
construct distributions of systems along luminosity, semi-major axis and
angular momentum, and make some conclusions on their evolution with time. We
made a comparison of the results with observational data and it shows a good
agreement. The set of theoretical models published in (Han et al. 2000) quite
adequately describes the observational data and, consequently, can be used to
determine the evolutionary path of specific close binary systems, their initial
parameters values and final stages.
