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、精确地获得测量结果。
In this paper, the principle of the hot-wire measuring method is discussed in detail. And, four insulating materials are measured in the different temperature by the efficient measuring method. Origin7.0 which is powerful software for data analysis and graph plotting is 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.
