摘　　要：通过模拟实验进行了细水雾作用下不同固体材料表面火蔓延特性的小尺度实验研究。实验在小型风洞中进行,在有细水雾和无细水雾作用的情况下,分别在不同来流速度条件下深入研究了4种典型固体材料表面火蔓延的规律,定性的描述了细水雾对不同固体材料表面火蔓延的抑制作用,通过比对分析,揭示了细水雾作用下不同类型固体材料表面火蔓延的变化规律,为细水雾的实际工程应用提供参考。With experimental measurement and analytical technology, the research of fire propagation over the surface of some combustible solid is conducted. Within mini-typed wind tunnel, the fire propagation over some typical solid surface under different air stream is studied. Four types of materials were studied： thin paper, typical upholstery wood （three-ply, five-ply）and the commonly used thick paper for packing. The effect with the conditions of water mist loading is analyzed and some results are gained, which may give some instruction for the project work.
