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。

Well I'm relying on the contract, if you like, that the manufacturer of square root put together, which is, if I know I'm giving it two floats, which I do because I make sure they're floats, the contract, if you like, of square root says I'll give you back a float.
