摘　　要：根据火灾动力学理论,建立了含壁面材料相关参数的轰燃前室内火灾温度的预测模型;选择铝塑复合板、PVC装饰板、PE保温装饰板和矿棉吸声板等常用新型装饰材料作为壁面材料,在小规模室内火灾实验箱内研究了轰燃现象;结合理论分析和实验研究结果,得到了轰燃时间的预测公式,并探讨了壁面材料特性对轰燃时间的影响。According to the fire dynamics theories,the predicted model of pre-flashover enclosure fire temperature,in which contains the relevant parameters of wall materials,is erected.Using some common new decoration materials such as aluminum-plastic composite panels,PP,PE and mineral wool panels as wall materials,the experimental study on the flashover phenomenon is carried out in the small-scale firebox.Combining the theoretical results and experimental data,the equation of predicting the flashover time is deduced,and the effects of wall materials＇ characteristics on the flashover time are discussed.
