ABSTRACT
Progress made in the determination of mass-loss rates, terminal velocities, and other parameters in the winds of the OB stars and the Wolf-Rayet (W-R) objects is considered. It is thought best to base mass-loss rates on the observations of the free-free emission of electrons in the winds, taking into account, for example, a detection in the radio wavelengths on the Very Large Array. It is found that mass-loss rates in hot stars depend on luminosity to some power. All of the studies, both observational and theoretical, have ignored the issues of variability.Questions regarding variability are examined, and requirements for its observation are discussed.
