Abstract:
This paper is to study the heat conduction equation related to ta . First, we start from the origin of the heat conduction equation. The general solution of the heat conduction equation is obtained by using the separation of variables method. Secondly, we study the existence, uniqueness and stabil-ity of the solution of ta heat conduction equation under three boundary conditions. Finally, Matlab programming and finite difference method are used to simulate the solution of the heat conduction equation. And the influence of the power of time and the numerical solution of the heat conduction equation is discussed.
