The best we've got is a compound called tantalum carbide, which can handle about 4,000 degrees Celsius max.

我们最好的材料是一种叫做碳化钽的化合物，它可以承受最高约 4000 摄氏度的温度。

This is a tantalum capacitor. Or at least we think it's a tantalum capacitor.

这是一个钽电容。或者至少我们认为它是一个钽电容器。

That is possible because this part of the transistor is made of tantalum pentoxide, a material whose atoms are arranged in a lattice which contains holes large enough for copper atoms to squeeze through.

这是有可能实现的，因为这部分晶体管是由五氧化二钽制造的——这种材料可以将它自身的原子排布在晶格中，这些晶格包括一些足够大的孔，可以让铜原子挤过去。
