摘要
根据瞬态热带法的基本原理,建立了测量非导电固体材料以及松散材料导热系数的实验装置,采用热电偶直接测量热带的温度变化,整个测量系统更加方便实用、易于实现。对一批试样进行的测试结果表明,本测量装置具有较好的重复性和准确性,可应用于相关的科研部门和工业部门。
Based on the principle of transient hot-strip method, an experiment apparatus is established to measure the thermal conductivity of electrically non- conducting solids and loose materials. The temperature variations of hot-strip are measured directly by using a thermal couple, which makes the whole experiment system more simple, practical and easily realized. The results for a group of samples show that the established apparatus has enough reproducibility and accuracy, and can be applied in scientific research and industrial fields.
