这意味着，我们要在主要布局容器宽度上使用百分数，比如主内容区域和边栏。

This meant that we use percentages on the main layout container widths, such as the main content area and the sidebar.

微博博主们：你曾和好友比过各自新浪或腾讯微博上的粉丝数吗？

Micro bloggers: have you ever compared the number of fans on your Sina Weibo or Tencent micro blog with those of your friends?

总节点数等于，主量子数减1。

And our equation for total nodes is just the principle quantum number minus 1.

The other thing that we took note as is what happens as l increases, and specifically as l increases for any given the principle quantum number.

另外一个我们要注意的是,ｌ增加时如何变化，特别是对于某个给定的,主量子数ｌ变化时如何变化。

So if we're talking about the fourth excited state, and we talk instead about principle quantum numbers, what principle quantum number corresponds to the fourth excited state of a hydrogen atom.

如果我们说的是,第四激发态，我们用,主量子数来描述，哪个主量子数对应了,氢原子的第四激发态？

We didn't just need that n, not just the principle quantum number that we needed to discuss the energy, but we also need to talk about l and m, as we did in our clicker question up here.

我们不仅需要ｎ,不仅要这个可以,决定能量的主量子数，还需要ｍ和ｌ,就像我们做这道题这样。
