Embodiment Construction
[0029] The present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments.
[0030] see figure 1 and figure 2 , the modified Fourier unsteady thermal conductivity differential equation of the first type of boundary conditions, that is, the analytical solution of the thermal conductivity differential equation when the surface temperature changes at constant velocity. During isokinetic heating or cooling, after a certain period of time, the temperature from the center to the surface of the solid changes at the same rate, so that the temperature difference between the surface and the center remains constant.
[0031] The solution of the Fourier differential equation of thermal conductivity when the surface temperature of different shapes of solid materials changes at constant velocity is as follows:
