| Abstract: | A criterion is proposed which enables breakdown of the parabolic model of heat conduction for isotropic materials, in which there are no phase transitions, to be revealed, and which defines the conventional boundary between the linear and nonlinear regimes of nonequilibrium thermodynamics in heat problems. __________ Translated from Izmeritel’naya Tekhnika, No. 6, pp. 38–42, June, 2008. |
