摘　　要：壁面材料对于腔室火灾及烟气发展有着重要影响,本文通过小尺寸室内火灾实验模型,选取三种典型不燃性壁面材料,针对不同的火源尺寸,研究壁面材料的表面辐射率、热惯性对烟气层分界面高度、温度的影响,研究结果对室内装修材料的选用以及抑制轰燃发生有着重要指导价值。Wall materials have an important influence on the development of chamber fire and smoke.In this paper,three typical non-combustible wall materials are selected through the small-size indoor fire experimental model.For different fire source sizes,the influence of surface emissivity and thermal inertia of wall materials on the height and temperature of smoke layer interface is studied.The research results have important guiding value for the selection of indoor decoration materials and the prevention of flashover.

关 键 词：室内火灾 壁面材料 表面辐射率 热惯性 烟气层 轰燃
