ON THE DYNAMICAL THEORY OF HEAT TRANSPORT PROCESS

In this article a dynamical theory of the heat transport process is developed. The concept of temperature difference between subsystems is introduced through the temperatures when they are disconnected and each of them is in equilibrium; we then treat the interaction between two subsystems as a perturbation. The rigorous expression of the coefficient of heat conductivity is obtained. For a large and uniform system, it is reduced to Kubo's formula.
