We slept on the hard ground, ate canned beans from cold metal plates and spent our days in the difficult search for gold.

我们睡在坚硬的地上，吃着冰冷的豆类罐头，还要整天寻找金子。

Because metal atoms crystallize so rapidly, scientists had to cool the alloy down incredibly fast, a million degrees Kelvin per second, by shooting tiny droplets at cold copper plates, or spinning ultrathin ribbons.

因为金属原子结晶极为迅速，所以科学家们必须极快地把合金冷却，大概是以一百万开氏度每秒，他们把微粒射向冷铜片，或者极薄的旋转带。
