When we talk about resonance structures, we're talking about cases that have the same arrangement of atoms the key is the atoms are the same, and the thing that is different is the arrangement of electrons here.

当我们讨论共振结构的时候，我们讨论的是原子排布相同情况,关键在于原子是相同的，不一样的只是电子排布。

So, when you think about resonance structures, some students tend to just get confused and be picturing this flickering back and forth.

那么，当大家想象共振结构的时候，有些同学很容易被弄晕,不停地来回想象。

So this is a case where we have resonance structures, or we call this a resonance hybrid.

因此在这种情况下我们就有了共振结构，或者我们叫它共振杂化。

When we talk about resonance structures, the key word is that the electrons are delocalized.

但我们讨论共振结构的时候，关键词应该是非局域化的电子。

But since in drawing Lewis structures actually, in some cases you do, you can draw a dotted line that means a 1 and 1/2 bond, but most in most cases, we just draw out both resonance structures, and the way that we say it's a resonance structure is that we put it in the brackets and we put an arrow between it.

但是由于在画路易斯结构时,其实，在某些情况下是可以的，你可以画一条虚线来表示一又二分之一键，但是在多数情况下，我们就把两个结构都画出来，而我们说这是一个共振结构的表示的方法是,把它们放在括号里，并在中间放一个双箭头。

So we'll talk specifically about drawing Lewis structures and then about formal charge and resonance, which are within Lewis structures.

因此我们会专门讲一讲,如何来画路易斯结构,然后再讨论形式电荷与共振论，它们也属于路易斯结构的范畴。
