Abstract
A one-dimensional harmonic chain model is used to study the non-equilibrium distribution function of phonons induced by a heat flux across the interface between two crystals. Conditions are derived which govern the matching of distribution functions on both sides of the interface. A generalization of the Enskog--Chapman method for calculating the Kapitza conductance is introduced. A precise relation is obtained under some simplifications. This version contains improved translation, modernized notation, and corrects one mistake, that does not affect the final formulae.
