The positive orientation method was applied to investigating in the shear flow the character and the sign of anisotropy of electric conductivity, as well as the coefficient of the rotary diffusion in two- and three- component lyotropic, liquid - crystalline systems. Comparing the character of anisotropy and its sign with the type of the texture observed, a conclusion is made on the presence of a lamellar mesophase with the plate micellar aggregates in the systems investigated. The size of these aggregates and their shape factors are evaluated at different concentrations of amphiphil.
