摘要
本文在分析热线法测量导热系数原理的基础上,应用热线法测定了几种保温材料不同温度下的导热系数。并通过Origin7.0对测量结果进行了数据线性拟合,可快捷、精确的获得测量结果。
This paper discussed the principle of the hot-wire measuring method in detail and four insulating materials were measured in the different temperature by the efficient measuring method. Origin7.0 which is powerful software for data analysis and graph plotting, was utilized during the data processing.The proposed method are of practical value,and can be applied to measure the thermal conductivity of various insulating materials.
