Comparison experiments of water mist with polycomponent water mist , and the test on polycomponent water mists extinguishing efficiency against ethanol and ethanol motor spirit fire were done
进行了多组分细水雾与细水雾的灭火性能比较，和用多组分细水雾对汽油火、乙醇汽油火的灭火性能试验。
It is proved that polycomponent water mist has better extinguishment efficiency than waer mist ; it is more difficult to put out a ethanol motor spirit fire than a motor spirit fire ; the work pressure what is needed to extinguish a ethanol motor spirit fire is higher than that for motor spirit fire
研究表明，多组分细水雾比普通细水雾具有更好的灭火效果，乙醇汽油火的灭火难度要比汽油火的大，多组分细水雾用于乙醇汽油场合灭火时，其灭火工作压力要大于用于汽油的场合。
