| Abstract: | The measuring principle and method of the material thermal conductivity that is a linear function of the temperature is proposed through the calculation of surface temperature in the third boundary condition. The experiments and calculations of different thermal conductivities for several materials have been performed with the measuring device designed. The results show that the method is simple and feasible. It has provided an effective method for the measurement of the variable thermal conductivity. |
