由于结合层往往是沿着外层金属的凝固线所形成的，因此在辊身表面所呈现的此类缺陷是不连续，不规则的。
As the interface follows the solidification front of the shell metal, the areas of soft core metal showing at the barrel surface, will be patchy and not continuous.
金属在熔炉或坩埚中预热到高于液化温度的一个合适范围内(不希望金属在浇铸完成前凝固)。
Metal is preheated in a furnace or crucible until is above the liquidus temperature in a suitable range (we don't want the metal solidifying before the pour is complete).
一般压力表适用于测量无爆炸危险，不结晶，不凝固及对钢及铜合金不起腐蚀作用的液体，蒸汽和气体等介质的压力。
Normal Pressure Gauge is applicable for measuring the pressure of liquid, steam and gas without possibility like explsion, crystal, solidification and erosion on steel or alloy cooper.
一般压力表适用于测量爆炸危险，不结晶，不凝固及对钢和铜合金不起腐蚀作用的液体、蒸汽和气体等介质的压力。
The normal pressure meter is suite measure some liquate, gas, steam medium pressure which has no corruption for copper and steel.
导热油的凝固点较低，能够在寒冷的冬季使用，即使万一凝固，因为它凝固时不膨胀，所以没有冻裂设备的危险。
The freezing point of heat conductive oil is relatively low and can be used in cold winter. Even if it is solidified, there is no expansion and no danger for cracking equipment.
空气似乎凝固了，烟笼着他的脸不走了。
