摘要: A general expression for the surface tension of a lattice gas is derived. The equation γA / kT = 〈η〉g − 〈η〉1, where γ tension, area, η related to eigenvector corresponding phase, and 〈 〉g 〉1 are averages performed in bulk liquid respectively. derivation, which incorporates rigorously defined local thermodynamic functions, similar some ways Cahn–Hilliard development. Numerical results obtained by applying Bragg–Williams approximation equation.
