摘　　要：现阶段,热流法、热箱法,热红外摄像仪法是我国测量外墙传热系数的主要方法.根据其自身的特点可用于不同季节与不同场所,但每种方法都不尽完善.对现有围护结构传热系数测定的主要方法进行了分析,并得出三种方法的优劣.At present, method of thermal current meter, hotbox method, infrared thermal perturbation of the external walls in China are main methods to measure the heat transfer coefficients. According to its own characteristics they can be used for different seasons and different places, but each of its methods is not perfect in itself. The building envelope＇s main detection methods of heat transfer coefficient are analyzed and their advantages and disadvantages are concluded.
