The temperature difference T/sub 1/--T/sub 2/ produced between the ends of a cylindrical intermediate-state sample as a result of longitudinal motion of the superconducting and normal domains under the influence of a current J at Tvery-much-less-thanT/sub c/ have been calculated and measured. The problem of the temperature distribution in the sample is solved in general form under the assumption that the thermal conductivity has a cubic dependence on the temperature. For an indium sample of 4 mm diameter and an approximate electron mean free path in the normal phase 10 mm the results of measurements at T=0.34 +- 0.01 K are in approximately sufficient agreement with the calculations by the parabola T/sub 1/--T/sub 2/ =-4 x 10/sup -5/J+1.5 x 10/sup -5/J/sup 2/, where J is in amperes. The distance between the thermometers on the sample was 8 cm.
