摘要：
It is shown on the basis of the solution of the kinetic equation for the gas of impurity excitations of superfluid mixtures He-3-He-4 that the relaxation of concentration and temperature occurs due to two modes (acoustic and dissipative). The parameters characterizing these modes are determined. The obtained results show that the relaxation of concentration and temperature of impuritons is completely determined by the thermal conductivity of the mixture and by the acoustic mode (second sound).
