| Abstract: | This article introduced minimum entropy production theorem of the simple heat conduction process and diffusion process, It deduced that the local entropy production rate and minimum entropy production theorem expression of there are two coupled thermal diffusion of irreversible processes. It proved that the minimum entropy production rate of thermal diffusion process is a linear relationship between flow and force, then the non - equilibrium steady state of heat power is a constant. |
