Fire-fighting foam is an aggregate of air-filled bubbles formed from aqueous solutions and has a lower density than that of flammable liquids. It is principally used to form a cohesive floating blanket over flammable and combustible liquids and prevents or extinguishes fire by excluding the air and cooling the fuel. It also prevents from reignition by suppressing formation of flammable vapors. Therefore, Fire-fighting foam can be used as a fire prevention, control, or exposure protection for flammable liquid fire hazards.

消防泡沫是一种填充空气的泡沫水溶液集合体，其密度比易燃性液体低，并可粘著、覆盖於易燃性与可燃性液体表面而达到隔离空气、冷却燃料及防止燃料持续蒸发引燃等功用，所以消防泡沫常使用在易燃性危险液体之预防火灾、制压火势及防阻延烧上。

当氦冷却到很低温度时，它会形成一种奇妙的液体。

"Water hardly ever freezes at 0 °C," says Brownridge."It usually supercools, and only begins freezing at a lower temperature."

布朗里奇说：水几乎从不在温度降到零度时冻结，通常是在更低温度下才开始冻结，也就是所说的过度冷却现象。

The cooling capability of water-cooling and oil-cooling was small and the currentdensity of the stator winding was low.

水外冷和油冷的最大冷却能力比较小，定子绕组的最大电流密度也比较低。

In addition, more than 20 kW of high-power lasers for welding of more than 10 mm thick steel plate, as a result of higher heat input, low cooling rate, the degree of hardening of the weld with manual arc welding and gas close to Paul.

另外，使用超过 20 kW的大功率激光器来焊接10 mm 以上的厚钢板，由于输入热量更高，冷却速度变低，焊缝的硬化程度将与手工电弧焊和气保焊水平接近。
