✦ Synopsis

On the basis of quasiton theory the equations of state were obtained for a two-component interface separating liquid and gas phases with a surface-active additive to the condensed matter. The first equation describes the state of a surface layer of a binary liquid, first for a liquid metal. The second equation is that of a surface layer of a vapor in contact with the condensate. With the help of these equations computations were conducted for the following systems: Fe-O, Fe-N, Fe-S, Hg-Na, Hg-K, Hg-Cs, 4 He-3 He. Except in the last case, the thickness l 1 of the surface layer of liquid is close to the atomic radii of the additives, for the most part, but the thickness l 2 of the surface layer of the gas is sometimes of an order of magnitude greater than l 1 .
