| Abstract: | The material conductivity plays an important role on the definition of the thermal process.Based on the thermodynamics,the measuring methods of the t hermal conductivity are classed into two kinds:the steady-state method and none quilibrium state method.And the measuring principles,characteristics and the a pplications of the two methods were compared.The results that the flat band met hod fits with the insulators and the hot-wire fits with the food. |
