摘　　要：模拟森林火灾中的地表火火场进行试验,以检验水介质灭火弹原理弹的灭火能力,对两组比药量不同的样弹灭火效果进行分析,确定影响爆轰水雾抛撒的几个因素。认为在一定范围内,比药量较大时灭火效果相对较好;灭火剂抛撒形成的爆炸水雾可有效降低火场温度;风对灭火剂抛撒后云雾形状影响较大;弹体结构对水雾形成扩散起决定性作用。The experiment simulating the surface fire scene in forest fire was carried out to test the extinguishing capability of water medium fire-fighting bomb,and extinguishing effect of two dispersal ratios were analyzed to confirm the factors influencing water mist pervading.It is believed that big dispersal ratio is more beneficial;water mist caused by fire extinguishing agent pervading can depress the fire ground temperature effectively;wind can affect the shape of water mist;and the configuration of bomb can influence forming the water mist decisively.
