为了解决"T"形法中的接触热阻问题,本文在不改变纤维与热线之间的接触节点的前提下,通过测量同一根纤维不同长度对应的表观热阻,同时得到了纤维热导率以及节点的接触热阻.用变长度"T"形法测量得到 Pt 丝以及两根沥青基碳纤维的热导率分别为 73,480 和 500 W m-1 K-1.

Based on a T-type probe, the thermal conductivity of an individual fiber and the thermal contact resistance of the junction between the fiber and the hot wire are simultaneously obtained,by measuring one fiber with different lengths when an identical junction is maintained. Using the changing length T-type method, the thermal conductivity of the Pt wire and two individual pitch-based carbon fibers are found to be 73, 480 and 500 W m-1 K-1, respectively.
