摘　　要：基于气承膜建筑材料燃烧特性试验,观察不同高度下气承膜材料燃烧的动力学现象,获得了气承膜燃烧的临界温度。实验中膜材料受热后表面收缩拉紧变薄,达到其临界温度后开始燃烧出现破洞,并伴有黑色浓烟生成,未出现引起二次火源的熔滴现象。通过Agilent 34970A采集温度数据,得到气承膜发生裂解燃烧破洞的临界温度约365.5～437.6℃。Based on the combustion experiment of combustion characteristics of air-supported membrane materials the fire dy- namic phenomenon at different heights was studied, and the combustion critical temperature of the membrane materials was obtained, shrinkage, tension and thinning appeared on the sur- face of the membrane materials after the material was heated. When the temperature reached the critical temperature, the membrane materials began burning, appearing a hole with a cloud of thick black smoke. In the course of the experiment droplet phenomenon didn＇t appear. Temperature data was col- lected by using the data collecting system Agilent 34970A. Re- sults show that critical temperature of the air-supported mem- brane material when the material begin pyrolysis and burn is a- bout 365.5 ℃ to 437,6 ℃.
