| Abstract: | Two mathematical models of determining thermal parameters of a class ofhomogeneous materials with the proof of existence and uniquness of solution are given inthis paper. These models are suitable for such materials as frozen earth, nonmetals andliquids, whose property of heat conduction is not so good. Comparing the first model ofthis paper with the previous work, the determination of heat flow is omitted and hencethe data needed here are the simplest. The result of numerical calculation shows thatunder the good conditions of experiments the model may be utilized in engineeringcalculation. |
