And you can do this any time if you have Lewis structures that you're choosing between.

而每当你遇到需要从几个可能的,路易斯结构中选择的情况。

And an important thing to remember when we talk about resonance hybrids is that the structure it's not 1/2 the time this structure, and 1/2 of the time this structure, it's actually some combination or some average between the two structures.

而当我们讨论共振杂化的时候,有一件重要的事情需要牢记,那就是这种结构并不是,一半时间处于这种结构的状态，而另外一半时间又变成了这种结构的状态，它实际上是两种结构在,一定程度上的组合或者平均。

And to try to explain why it was that absolute rule came to europe at the time it did, one has to not only look at the particular structures of states, but one has to look at the overview and the sheer horror of it all.

要解释为什么绝对主义在这个时候遍行于欧洲,我们不仅要着眼于各国特有的社会结构,还要纵观全局,了解当时社会上的恐慌

We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.

我们并不想每次都去解薛定谔方程，而且实际上，一旦我们开始讨论分子，我可以想象,你们中没有一个人，不管你有多么热爱数学或物理，会想去解这种情况下的薛定谔方程,总之，路易斯结构能让我们,有超过，90%，的概率判断出正确的,电子排布。

But they're not accurate all the time in predicting bonding within molecules, and the reason for this is because Lewis structures are not, in fact, based on quantum mechanics.

但它们在预测分子内,成键时不总是正确的，这是因为Lewis结构，实际上不是基于量子力学的。

So far we've exclusively been using Lewis structures any time we've tried to describe bonding within molecules.

目前为止任何时候我们尝试要,描述分子内的成键,我们都是利用Lewis结构。
