    Abstract:

    The interaction of phonons and the thermoequilibrium of a crystal are analyzed with Boltzmann equation and Landau equation.The thermoequilibrium of a crystal is the result of interaction of phonons.There is no interaction of phonons in the harmonic approximation. A cbystal can not reach the state of thermoequilibrium in the harmonic approximation.
