Often a good thing to start with is to put the lowest ionization energy atom in the middle, and if you don't have charge separation then go with that structure, but if you do find you have a lot of separation, such as the case in negative 2, positive 2, and minus 1, then you want to say wait a second, this is really bad in terms of formal charge, let me go ahead and see what other options I have here.

通常一开始把电离能最低的原子,放在中心位置就很好了，如果你发现电荷没有分开,那么这个结构就没问题了，但是如果你发现有很多分开的电荷，比如这种情况，有负二，正二和负一，那么你会想要说等一下，从形式电荷来看这很不好，让我去看看其它可能的选择。

So what we see is that structure a is the most stable because we have the least separation of charge in the case of structure a.

因此我们看到结构，A，应该是最稳定的,因为这种情况下,分开的电荷最少。

Here that omniscient narrator, as when that narrator looks in to Haze's mind, offers you a reading of the sky and its separation from the minds of the characters that suggests, or makes you look for, kinds of structure.

在这里，万能的叙述者读解Haze的内心时，给了我们关于星空的注解,角色们迥然不同的想法,暗示了我们，或者说使得我们，去寻找一种结构。
