熔化

If an acetylene cylinder fire could involve additional acetylene cylinders, it is very important to spray a large quantity of water on adjacent cylinders to cool the cylinder and prevent the fusible metal plugs on the adjacent cylinders from becoming heated, melting, and discharging additional acetylene.

如果一个乙炔钢瓶的着火连累了另外的乙炔钢瓶，在附近钢瓶上喷洒大量的水来冷却钢瓶，防止附近钢瓶的易熔金属塞受热、熔化和排放出额外的乙炔，这是非常重要的。

The fusible plug device is a nonreclosing pressure relief device designed to function by the yielding or melting of a plug of fusible metal.

易熔塞装置是一个非重闭减压装置，通过易熔金属制成的塞子的变形或熔化发挥作用。

Gas cylinders are protected from rupture due to fire by a frangible disc sometimes backed by a fusible metal with a melting temperature of about 212°F(100°C).

用破裂盘，有时后候后面还有一个熔化温度为212°F(100°C)易熔金属，来保护气体钢瓶，防止由于起火而破裂。

The experimental result shows that when the discharge time was more than 1.5μs, small crack emerged in the fuses due to mechanical force on the heated fuse, and the metallized layer would be evaporated as the crack became long enough to generate disruptive discharge. When the discharge time was less than 150ns, small crack emerged in the fuses due to the current heat, and the metallized layer would be evaporated as the crack became long enough to generate disruptive discharge.

实验结果表明：当熔丝的通流时间大于1.5 ms时，电流热效应产生的机械力使安全膜熔丝的金属层产生微小裂纹，当裂纹达到一定长度，两端发生击穿放电，金属层因蒸发而断开；当熔丝中通过较大的电流时，短时间内(50 ns)的电流热效应使熔丝金属层发生熔化产生裂纹，裂纹两端发生击穿放电，金属层因蒸发而断开。

The active power increase allows a faster melt in the electric arc furnace, thereby saving energy consumption.

有功功率的增加，使电弧炉中的物料熔化更快，从而节约能耗。

Process of settling down of Zr particles in melt was calculated by using second law.

利用牛顿第二定律计算了熔化过程中Zr 颗粒的沉积规律。

Detection of a human cause of warming at both ends of the earth also strengthens a need to understand ice sheets on Antarctica and Greenland that would raise world sea levels by about 70 meters (230 ft) if they all melted, they said.

温暖的人的起因的Detection在地球的两个末端也加强需要了解在南极州的冰床，并且将由大约70米的格陵兰(230 ft)提高世界海标准，如果他们全都熔化了，他们说。
