We discuss the interaction between two-level systems and the phonon field in non-crystalline dielectric solids, and we calculate the quantum transition matrix elements of such an interaction. After studying the Boltzmann equation for phonon transport, we obtain the phonon distribution function. From a direct calculation of the heat current, and as a result of obtaining the thermal conductivity of non-crystalline dielectric solids, the T2 relation is obtained.
