Abstract When considering transient X-ray sources and some types of cataclismic variables various kinds of problems may be resolved for nonstationary disc accretion. The evolution of viscous duscs is analytically studied within the frames of linear model equations [1]. The general nonlinear problem is condsidered only numerically [2,3,4]. This work illustrates the evolution of the disc as subdivided into several natural stages, each one of which is described by a self-similar solution of the initial equation. These solutions representing asimptotic of the real problems provide very important information, which does not follow nessesarily fromnumerical computations [5,6,7,8,9].
