But some amalgams aren't so harmless.

但有些汞合金并非是无害的。

Yes, sir. Mixed with mercury, it forms an amalgam that takes the place of zinc in Bunsen cells.

是的，先生。钠跟汞混合，成为一种合金，代替本生电池中所需要的锌。

An alloy with mercury in it is called an amalgam, and they're useful for all sorts of things.

含有汞的合金称为汞合金，们可用于各种用途。

When that amalgam meets the air, it stills turns into aluminum oxide — except this time, because there's mercury involved, the reaction doesn't stop.

当这种汞合金遇到空气时，仍然会变成氧化铝——除了这次，因为有汞，反应不会停止。

For example, if you've ever gotten a silver filling at the dentist, that's a harmless amalgam of metals like mercury, silver, and copper.

例如，如果你曾经在牙医处银填充的话，那是一种无害的金属混合物，如汞、银和铜。

If mercury can get to the pure aluminum, like through a scratch on the plane, it immediately starts to react and seep into the metal, forming an amalgam.

如果汞可以接触到纯铝的话，就像通飞机上的划痕一样，会立即开始反应并渗入金属中，形成汞合金。

The evidence for people's response to recognition is everywhere: the Star Wars franchise, for example, is an amalgam of characters and themes from older films.

比如，《星球大战》就是多部老电影里的人物和主题的混合。
