And because Form IV has a lower melting point than Form V, the unwanted crystals melt again.

由于形态4比形态5熔点低，不要的晶体再次熔化。

Bricks will stand a great heat without melting, especially those made from a kind of clay which is called fire-clay.

砖可以承受很高的温度而不熔化，特别是那些用“耐火粘土”做的砖。

While it can technically be recycled, it's not particularly practical, because a truck full of lightweight, air-filled Styrofoam doesn't melt down into a lot of polystyrene.

尽管从技术角度能被回收，但是不是特别实用，因为一卡车又轻又蓬松的泡沫塑料并不能够熔化成大量的聚苯乙烯。

In other works a much greater fixed capital is required. In a great iron-work, for example, the furnace for melting the ore, the forge, the slit-mill, are instruments of trade which cannot be erected without a very great expense.

在其他工，要更多的固定资本。例如，在一个大的炼铁厂，熔化矿石的熔炉、锻炉、切磨机都是贸易工具，如果不花费很大的费用就无法建造。
