On the basis of this model an analysis of the accuracy of the two-temperature model in the area of low temperatures is carried out and the more accurate three-temperature model is proposed. In contrast to the two-temperature model, the new model explicitly takes into account the contribution into the electron cooling kinetics of a specific group of phonons, which collide with the boundary "film-substrate" at angles exceeding the angle of the internal reflectance. The heterogeneous nucleation of a new phase for the Van der Waals fluid on rough surfaces is investigated witnin the generalized Gibbs model. The heterogeneous nucleation (condensation) on the imperfect solid surface of the liquid droplets from the vapour described by the Van der Waals equation of state is investigated. It is shown that in the generalized Gibbs approach the contact angle and the catalytic factor for the heterogeneous nucleation depend on the extent of the vapour supercooling.
