这金属最大的一个优点就是不生锈。

One great advantage of this metal is that it doesn't rust.

《牛津词典》

金属热处理过程其实是一系列具体的操作，通过这些操作加热与冷却金属，但加热时进行控制，使得金属不达到熔融的状态。

The process of heat treating is the method by which metals are heated and cooled in a series of specific operations that never allow the metal to reach the molten state.

在隔离状态下镓盐与有机复合物皆不导电，但Hla和他的同事们有证据表明由这两种物质组成的金属线有超导特性。

In the isolated state gallium salt and organic compounds are non-conductive but Hla and his colleagues have evidence that these two substances formed by the metal lines are superconducting properties.

now we're not just talking about 1 photon, 1/2 let's say we shoot them all at the same time at our metal, each of them having some energy that's let's say 1/2 the work function. So, just to take a little bit of an informal survey, who thinks here that we will have an electron that is ejected in this case?

我们现在不仅仅讨论一个光子，它们所具有的能量是功函数的，我们在同一时刻把它们打到金属上,我们做一个不太正式的调查,谁认为这种情况下,一个电子会被打出？
