摘　　要：针对现有导热系数现场检测方法存在的局限性,基于墙体非稳态传热的频率响应理论,提出了一种求解单层均质墙体导热系数和体积比热的传热学反问题方法,并进行了实验验证。结果表明,此方法应用于导热系数和体积比热的现场检测时,具有一定的可行性和便捷性。In view of the limitations of the existing thermal conductivity field detection methods,based on the frequency response theory of unsteady heat transfer of walls,an inverse heat transfer method was proposed to solve the thermal conductivity and volume specific heat of singlelayer homogeneous walls,and experimental verification are carried out. The results show that this method is feasible and convenient in the field detection of thermal conductivity and volume specific heat.
