摘要
目前现场测量建筑围护结构热阻普遍使用算术平均法，本文根据实际中遇到的一些问题，阐明了动态分析法的原理，并编制了动态分析法处理数据的程序。通过在实验室中用热箱法验证了动态分析法理论以及自编程序的正确性，并通过现场工程检测验证了动态分析法用于实际工程的可行性，说明动态分析法能够在保证一定准确性的同时缩短测量时间，提高现场测量围护结构的工作效率。
Average method is widely used in in-situ measurement of thermal resistance of building envelope. Based on practical problems,the theory of dynamic analysis method was presented in this paper, and the related program was compiled. Both the theory and the program were experimentally validated by thermal-box method,and the feasibility of dynamic analysis method for factual projects was proved by in-situ measurement. It was concluded that the testing period could be shorted with the suitable accuracy and the work efficiency could be improved.
