| Abstract: | Based on the basic principle,this article determines the higtest power exponent of power series expansion of the free energy density,depending on the characteristics of changing physical parameter and nonho-mogeneous compound material. By taking use of the limit of entropy density on free energy density,it deduces changing rate of entropy density. Then by being combined with constitutive equation of changing physical parameter and nonhomogeneous compound material,it deduces the heat conduction equation of changing physical parameter and nonhomogeneous compound material. |
| Keywords: | changing physical parameter nonhomogeneous compound material heat conduction equation |
