Scientific paper

The results of observations carried out in 1984 and 1985 of single Wolf-Rayet stars HD 192 103 and HD 192 641 and the eclipsing binary HD 193 576 are presented. Variability of the equivalent widths of the spectral lines in HD 192 641 was found on only one of the ten nights of observation. In the case of HD 193 576, large-scale anisotropy of gas flows which is stable for several decades is shown to exist.
