Scientific paper

Spectral observations have been carried out and the spectrum variations during the orbital period have been studied. It is shown that outside eclipses the equivalent widths of the emission lines are constant, and during the eclipse moments they increase. The radial velocity curves from H and He II lines are strongly distorted sinusoids. This distortion is explained by the escape of matter from the system which indicates a supercritical-accretion regime. A model of the system is suggested.
