摘　　要：简要介绍了建筑围护结构导热系数的现场检测方法,指出了现有检测方法存在的局限性。基于谐波反应法,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,并进行了模拟验证和实验验证。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。The field detection methods of thermal conductivity of building envelope are briefly introduced pointing out the limitations of existing detection methods. Based on the harmonic response method,an inverse heat conduction problem method for solving the thermal conductivity and volume specific heat of single-layer homogeneous wall is proposed,and simulation and experimental verification are carried out. The results show that the method is feasible and convenient to be used in the field detection of thermal conductivity and volume specific heat.
