Embodiment Construction
[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0048] see figure 1 and figure 2 , the modified Fourier non-steady-state heat conduction differential equation with the first kind of boundary condition, that is, the analytical solution of the heat conduction differential equation when the surface temperature changes at a constant speed. When heating or cooling at a constant rate, after a certain period of time, the temperature from the center to the surface of the solid changes at the same speed, so that the temperature difference between the surface and the center remains constant.
[0049] When the surface temperature of solid materials of different shapes changes at a constant speed, the solution of the Fourier heat conduction differential equation is as follows:
