摘　　要：搭建实验平台,针对3%和6%的水成膜泡沫灭火剂,研究其发泡倍数在5~17范围内变化对扑救油池火的灭火时间及抗烧性能的影响。实验结果表明,两种灭火剂均可有效灭火;发泡倍数越大,灭火时间越短,17倍时比5倍时的灭火时间缩短近50 s;发泡倍数越大,90%抗烧时间越长。An experimental platform was built, considering AFFF of 3% and 6%, the influence of the expansion ratio on pool fire ex- tinguishing time and fire resistive performance when the expansion ratio is between 5 to 17 was studied. Experimental results showed that, two kinds of fire extinguishing agent can both put out the fire effectively; the bigger the expansion ratio, the shorter the fire extinguishing time, and the extinguishing time when the ratio is 17 is 50 s shorter than the time when the ratio is 5; the bigger the ratio, the longer the 90% fire resistive time.
