【Abstract】 According to the law of Wiedemann-Franz,the ratio of thermal conductivity and electrical conductivity of metal is constant.In this paper,the electrical conductivity of the material is measured at a certain temperature,then the thermal conductivity of the material is calculated based on the resistivity,the result is similar to that obtained using thermal-wave method.更多还原
