But secondly again Homer and the poets sing the virtues of men at war.
另外,荷马与其它诗人,歌颂战士的美德;
This is incredibly important because if you picture having a double bond in a very large molecule, you could have all sorts of other atoms off this way and all sorts of other atoms off this way, and you can picture the shape would be very different if you have one confirmation versus another confirmation.
这是十分重要的,因为如果你想象在一个大分子里有一个双键,你可以在这里有各种各样的其它原子,在这里也有各种各样的其它原子,你可以想象一个构型,和另外一个构型之间的形状差别是非常大的。
that's one way to think about it, and there's also another way, and this is the way that your book presents it. If you, in fact, have two of the same atom right next to each other, let's say you have a crystal, or let's say you're talking about a metal, what you can do is just look at the distance between the two nuclei, and split that in 1/2, and take the atomic radius that way.
这只是一种定义的思路,另外还有其它方法,也就是你们课本上的方法,如果你,事实上,有两个相同的原子彼此靠在一起,比如说你有一个晶体,或者说你讨论的是一个金属,你所要做的就是,看看这两个原子核之间的距离,然后将距离除以二,就得到了这个原子的半径。
