Originální abstrakt

Two alternative methods for measuring emissivity of opaque grey diffusive materials are presented. The first method is based on direct computations of emissivity in the form of a fraction consisting of three temperatures, namely the contact and contactless temperatures of the tested sample and the temperature of the laboratory hall envelope. The second method is based on the functional dependence between the contact and contactless temperatures of the measured sample. This dependence is fitted by a linear function. Fitting parameters provide the value of emissivity and the radiant temperature of the laboratory hall envelope. Both these methods seem to be convenient for student laboratory work.
