摘要
本文将动态法测定良导体温度分布的数据通过origin软件拟合得到热波线性成分的斜率及热波振幅,验证了热波振幅随距离指数衰减的规律;利用拟合数据精确的计算出了良导体的热导率,避免了热波峰值法计算热导率的不合理性。
The temperature distribution of good conductor were measured by dynamic method. The slope of linearity and the swing for the thermal wave were obtained by fitting the data of the temperature distribution with Origin software. The exponential attenuation law was verified. The conductivity of the good conductor was calculated precisely which avoided the calculation inaccuracy using the thermal wave swing.
