摘　　要：以Ａ．Ｂ．Ｌｕｉｋｏｖ热湿迁移理论为基础，根据严寒地区的气候特点，分析研究了建筑墙体的温湿度分布，并对其隔热性能的动态特性作了预测，利用建筑足尺构件热工实验台进行了实测研究，计算结果与实测结果比较一致．By application of A. B. Luikov's theory of heat and moisture transfer and in the light of the climatic characteristics of the severely cold regions, the temperature and moisture distributions in building walls are analyzed, and its dynamic thermal insulstion behavior is predicted. The experimentul study has also been carried out using a full scale hot box test unit. On the whole, the calculated results are in agreement with the experimental results.
