| 摘 要： | 维德曼-弗兰兹定律指出金属的热导率和电导率的比值是常数,本文先测量了一定温度下的材料的电阻率,再由电阻率计算出材料的热导率,并与利用热波法得到的热导率进行比较,其结果相近.

| 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. |
