Scientific paper

The presence of alpha-viscosity in the atmospheres of accretion discs is investigated. It results in the existence of coronae and/or winds. When discs are illuminated by the central X-ray sources, the mass loss may be a significant fraction of the total mass transfer rate. The optical depth of the wind depends strongly on the viscosity parameter. The constancy of the relative X-ray eclipse depths in some X-ray sources is discussed.
