摘　　要：建立了压缩空气泡沫灭火试验装置和试验储罐,对储罐液下泡沫喷射灭火技术进行了试验研究,研究结果显示:发泡倍数和泡沫液流量对灭火效果影响明显,而储罐泡沫的注入位置对灭火效果影响较小;液下喷射的发泡倍数宜控制在5~7之间,发泡倍数超过8后,泡沫层含油量超过40%,无法控火;泡沫混合液供给强度宜取5.0 L/(min·m^2),供给强度加倍后,无法控火;在适宜的试验条件下,控火时间在40~45 s。The compressed air foam system and tank have been constructed for experiments of subsurface foam injection. The results showed that the foam expansion ratio and foam application rate played an important role in fire extinguishment while the foam injection position did not. The preferred foam expansion ratio was among 5 ～ 7 and if it was over 8,the oil content in foam layer would exceed 40% which could lead to failure of fire control. The appropriate foam rate was 5. 0 L /（ min·m^2） and it would fail to control fire if it was doubled or more. The time to control fire was about 40 ～ 45 seconds under preferred conditions.
