| Abstract: | 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 is measured directly by using a thermal couple, that 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. |
