To put it differently, in order to know what "Dogs" means, you never had to learn the word "Dogs."

换个说法,为了知道"狗狗们"的意思,你不需要去学"狗狗们"这个词

So what that means is that's how much energy we would have to put into a hydrogen molecule in order to get it to split apart into its two atoms.

它的意义,就是我们需要向一个氢分子中注入这么大的能量,才能将它分解成两个独立的原子。

You've got to put some nice perfume onto it, in order for it to be useable, just as your soap would be pretty horrible without any perfume on it.

你要在其中加入好闻的香料,以便使用,就像肥皂,如果没有香味会很恐怖

How did we put our gene fragments into this plasmid DNA in order to make multiple copies of it, or to clone the gene?

如何把基因片段整合到质粒DNA上,来获得大量拷贝,或者说来克隆基因呢

If we have a higher z effective, it's pulled in tighter, we have to put in more energy in order to eject an electron, so it turns out that that's why case 2 is actually the lowest energy that we need to put in.

而如果有效核电量更高，原子核的束缚也就更紧，我们不得不输入更多的能量来打出一个电子，这就是第二种情况,所需要输入的,能量更少的原因。

You got an extra hint here in terms of the order, so even if you had just forgotten what I said, sometimes it's not a terrible idea just to put it in the order it's written, that can give you a lot of clues as well.

其实大家还可以发现一个额外的提示，因此即使你忘了我刚才说的，有时候直接按照这个顺序,排列也不失为一个办法，这也可以给你很多提示。

The reason it's aluminum is because aluminum has a lower z effective, so it's not being pulled in as tightly by the nucleus, and if it's not being pulled in as tightly, you're going to have to put in less energy in order to ionize it, so that's why it's actually going to have the smaller ionization energy.

原因是,铝的有效核电量更少，所以没有被原子核束缚得更紧，而如果没有被束缚得更紧，你为了电离它所需要注入的能量也就更少，这就是,它的电离能会更低的原因。
