中文摘要：
本文在“T”型加热法的基础上，提出了一种能同时测量单根纤维真实热导率和热扩散率的实验方法。通过在“T”型加热法的热线中通入不同频率的交流电，可以改变被测纤维热渗透厚度，将热线与纤维节点的接触热阻和纤维的真实热阻分离，进而得到纤维的真实热导率和热扩散率。
英文摘要：
Based on the T-type probe, a novel method was proposed to determine the intrinsic thermal conductivity and thermal diffusivity of a single fiber. In this method, the hot wire was supplied with an alternating current to generate a temperature oscillation at the junction, and the penetration depth of the temperature oscillation in the fiber was changed with the frequency. Finally, the thermal contact resistance and the intrinsic thermal resistance of the fiber could be separated, and its intrinsic thermal conductivity and thermal diffusivity could be obtained.
