So, when we think about a bond length, this is going to be the length of our bond here, that makes sense because it's going to want to be at that distance that minimizes the energy.

因此，当我们考虑一个键的长度的时候，这就应该是我们的键长，这是合理的,因为体系会在核间距达到这一距离时,能量到达最小值。

And so what I get is the energy of the system at the equilibrium separation is given by minus z plus.

这就是通过减去z+得到得平衡分离时,我得到的能量体系。

So we know we always want to have our systems in as low an energy as possible, so it makes sense that a bond would happen any time we got a lower energy when we combine two atoms, versus when we keep them separate.

我们知道我们总是希望使我们的系统,处于能量尽可能低的状态，因此就应该有化学键产生,一旦我们合并两个原子之后体系的能量变得更低，相较于分开时。

That's pretty good 'cause now, I can pretty much cover my American keyboard pretty effectively both upper case, lower case, and a whole bunch of punctuation. For other languages as in aside, there are other encoding schemes when there are more characters.

那是相当不错的，它可以包含整个美式键盘中的字符,包括大小写字母和一连串标点,对于其他语言，当涉及更多字符时就会有其他的编码体系。

If you don't account for them all in your design, the system may not work.

若设计时不能全面考虑，该体系就行不通。

You can see that when Wimsatt and Beardsley talk about the "success" of the poem, they understand the whole critical enterprise, - including its theoretical underpinnings-- the question of what is a poem, - the question of how should we best read it-- to be still geared toward literary evaluation.

大家应该发现，当文萨特与比尔兹利谈到,诗歌创作的“成功“一词时，他们完全理解了文学评论体系，这包括适用于文学评估的理论根基-,就是那些关于什么是诗歌，还有我们如何解读的问题-,这些都对文学评估很重要。

It is essentially equal to internal energy for condensed systems, but when you look in the books sometimes they will use this term.

它与内能是相同的,在凝聚体系中，在你看书时有时你会发现,它们会这样使用。
