The copper plates conducted heat rapidly to and from the bismuth telluride, thus maintaining the temperature difference.

铜片可以把热地传递到碲化铋上或从碲化铋上导出，这样就能保持气温差。

Her image was captured on a copper plate with finely polished, shining silver in the middle of the 19th century.

她形象是在 19 世纪中叶用精细抛光、闪亮银色铜板上拍摄。

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，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，或者极转带。

The third objective, efficient design, involved sandwiching the nanostructured bismuth telluride between two copper plates and then enclosing the upper plate (the one coated with the light-absorbing oxides) and the bismuth telluride in a vacuum.

第三个目标是高效设计，它涉及到把纳米级碲化铋夹在两片铜片之间然后把位于上方片（这个片被覆盖上了吸收光线氧化物）和碲化铋封入一个真空内。
