摘　　要：被动式蒸发屋面在一定的构造模式下,具有良好的隔热效果及环境效应,但目前所研究的被动蒸发屋面大多集中在蓄水屋面、植被屋面,对骨料厚度不同的蒸发屋面的研究较少。膨胀珍珠岩本身具有良好隔热效果,在屋面同一区域分别建立的6个厚度不同、构造相同的膨胀珍珠岩模块,通过对连续晴天时段数据的观测和分析,发现不同厚度的膨胀珍珠岩模块对温度在衰减度、延迟时间等方面有一定的差异。The passive evaporation roof with certain structural model has good insulation impact and environmental effect,but the current study on passive evaporative roof is mostly focused on the water pool roof and green roof, the research on the different thickness aggregate evaporative roof is relatively few. Expansion perlite has good insulation characteristics. In this experiment six kinds of expansion perlite module with different thickness and same structure were established in the same roof. By analyzing the experiment data during the succession sunny days,it is found that expansion perlite module with different thickness has differences at degree of decay and delay time of temperature.
