摘要：

Equilibrium and dynamic surface tension of some foaming agents used in fire-extinguishing media were detd. by static and dynamic methods. In particular, the surfactants with perfluoroalkyl groups in the structures of their mols were taken into consideration. The surface tension isotherms were plotted and the basic parameters specific for surface activity of the studied compds. were calcd. The diffusion coeffs. were evaluated by using the Ward-Tordai equation.
