The molecular-dynamics method has been used for calculating the density profiles of the mixture argon-neon, surface tension, and adsorption in systems of 4096-8957 Lennard-Jones particles at a reduced temperature T* = k(B)T/epsilon(alpha)similar or equal to 0.7 +/- 0.01 and a pressure up to p* = p sigma(3)(alpha)/epsilon(alpha) = 0.6, where sigma(alpha) and epsilon(alpha) are parameters of the argon potential. The results of calculating, phase-equilibrium parameters are compared with data for a single-fluid model of a solution. The paper discusses the applicability of an extended version of the van der Waals capillarity theory to the description of the surface tension of a gas-saturated liquid.
