For binaries with well-known orbital parameters we describe methods to restrict some characteristics of the WR star in the binary, such as Te and RWR(τ ≃ 1). The presence of a hot, luminous companion helps to address the question of spherical symmetry of the WR wind and reveal the ionization stratification in the wind. Also, we discuss the restrictions which can be imposed on the wind velocity law(s).
