摘　　要：研究可熔材料采光带自然排烟方式的可行性。在某厂房内进行了全尺寸的实体火灾实验,记录了顶棚烟气层温度。实验发现,对于高大空间建筑,当火源功率较小时,可熔材料采光带不能够有效开启。从理论的角度对可熔材料采光带自然排烟方式可靠性进行了分析,认为可熔材料采光带自然排烟方式可行性需要根据建筑的具体情况做出判断。特别是当建筑高度过高时,可熔材料采光带作为自然排烟方式需要理论或实验数据支持。In order to study the feasibility of using fusible materi- al Lighting Belt for natural smoke exhausting, an experiment of a full-sized entities fire in a factory was made. It was found that for large space building with fire power small, fusible material Lighting Belt can not effectively open. According to the experi- mental phenomenon, and from the point of the theory analysis, result shows that the feasibility of using fusible materials Light- ing Belt for natural smoke exhausting should be on the basis of the specific circumstances of the building. Especially when the height of the building is too high, the natural smoke exhausting with fusible material Lighting Belt requires theoretical or exper- imental data support.
