It is shown that, in the framework of such approach, the Tolman length determining the first-order curvature correction to the surface tension, γ, is equal to zero. In the range of small values of the radius of curvature, R, the mechanical approach overestimates considerably the value of γ. For the Lennard-Jones potential the non-analyticity in the dependence γ(1/R) is found at 1/R = 0. It disappears for potentials decreasing more rapidly with the distance between the particles Доп.точки доступа: Baidakov, V. G.; Байдаков Владимир Георгиевич; Болтачев Грей Шамильевич
