摘　　要：以97#汽油为燃料,分不同的摆放位置,在大、小两间灭火室内进行油池火灭火实验,分别对油池火和灭火剂的空间位置对灭火时间的影响进行实验研究。采用正交实验方法确定粘合剂和调节剂的比例。结果表明:灭火浓度不变,当灭火剂处于灭火室底部中心位置时,随着油池火与边壁距离的增加,灭火时间呈现增大的趋势。灭火剂的空间位置不同,灭火介质扩散分布不均匀,对封闭空间的灭火时间有很大的影响。当灭火剂置于封闭空间中心位置时,具有最快的灭火效率。The 97 # gasoline was ence of space position of pool fire selected to research the influ and extinguish agent on extin guishing time. The experiments were carried out in big room and small room. The ratio of adhesive and regulator was deter- mined by Orthogonal experiment. The results indicated that in- creasing distance of pool fire to the wall enhanced the extinguis- hing time when the extinguishing agent lied in the center of ex- tinguish chamber with the same extinguish concentration. Different space position of extinguish agent leaded to unevenly dis tribution of extinguish medium, which had great influence on the extinguishing time in the closed room. When the extinguis- hing agent was placed at the center of the closed room, extin- guishing time was the shortest.
