摘　　要：在现实生活住宅环境中,研究墙体保温对墙体的衰减倍数和延迟时间的影响具有重要的意义.通过实验测试,比较有无保温层墙体的内表面温度对室外温度的衰减系数和延迟时间的大小.此外,建筑墙体的衰减系数和延迟时间不仅受本身墙体的材料等影响,还受到室内的热源、室外的天气等影响.It is important to study on the residential environment of the thermal insulation and time prolongation effect of the wall. Through the experimental test, the attenuation co-efficient and the time prolongation of the inner surface temperature of the heat preservation layer in the wall are compared. Moreover, the attenuation coefficient and time prolongation of the building wall is not only influenced by the material of wall itself, but also by the heat source and the outdoor weather.
