ABSTRACT
For a solid-vapour or liquid interface, the mobile subsystem is always in an equilibrium distribution. It is ‘tuned’ to a given nonequilibrium state of a solid (including an adsorbent). Formulas for the function F(t), G(t), S(t), U(t) can be expressed in the same way in terms of the local concentrations θ iq(t) and the pair functions θi jqp(t), regardless of whether they are equilibrium or non-equilibrium [90]. The functions θiq(t) and θ
equations of the processes that formed the boundary of the phases to a given instant of time. Therefore, the corresponding non-equilibrium analogs of surface tension can be calculated through them as an excess of the surface free energy σ(t), which depends on time. These characteristics, being a function of time, pass to the limiting values of the equilibrium surface tension over long times (for this, it is important to fulfill the self-consistency condition – Chapter 6).
