He needs to know about the structures of the molecules, because if the structure is wrong it's not going to work.

他想要让它们成键，他需要知道分子结构，因为如果结构不对。

The structures in the brain which would underwrite the ability to engage in P-functioning, they're not destroyed by suspended animation.

存在于大脑中的,能够支持人格功能的结构，并没有被假死状态所破坏。

And the last thing we do for any of our structures to check them and figure out are these valid or not valid, are these good Lewis structures is to check the formal charge.

而为了检验任何一个结构是否有效,看它们是不是好的路易斯结构,我们要做的最后一件事就是检查形式电荷。

They're all structures. In other words, they're not organic.

它们都是建筑，换句话说，都不是有机体。

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

What I'm going to talk about today is to continue our discussion about what is Biomedical Engineering and go a little bit further and we'll spend about half the class doing that, and then I want to spend the last half of the class talking about some biological structures that are very important and that you might not be familiar with.

今天我们要继续讨论,有关生物医学工程的话题,并且更深入些,这需要花上大约半节课时间,后半节课会讨论,一些非常重要的生物构造,有些你们可能不是太熟悉

And resonance is the idea that sometimes one single Lewis structure does not adequately describe the electron configuration around a given molecule, so instead you need to draw two different Lewis structures to describe that more appropriately.

而所谓共振态,就是有时候一个路易斯结构不足以,完整描述一个给定分子的电子排布，因此这时你需要同时画出两个,不同的路易斯结构来描述它,这样会更恰当。

Now, out of all of this, again to repeat, we are not making the argument that the Thirty Years' War itself led to absolute rule, that the growth of state structures can be seen in the beginning and the late medieval period with the consolidation of these territorial monarchies.

综上所述,我再重复一遍,我们并不能推断说,三十年战争本身导致了绝对主义的发展,国家的构建在中世纪的早期,以及晚期的领土兼并中就已经初见端倪

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。

This was something we could not predict using Lewis structures, but we can predict using MO theory that we have a radical species here.

这是我们从Lewis结构里不能预测的，但我们可以用分子轨道理论,预测自由基。

We have two lone pairs, so if we thought about what the bonds were everywhere, 5° it would be 109 . 5, but it's bent because we're only looking at the bonds, we're not counting the Lewis structures in naming our geometry, but they do affect the angles.

我们有两个孤对，所以如果我们考虑它会成怎样的键时，应该成109。,但它是折线型，因为我们只考虑成键，在几何形状里不考虑Lewis结构，但它会影响角度。
