We're going to have other ways of building them, but it could be a collection of all the primes. Hm.
但是我们很快就要学习到,实际上这些集合是可以是任意的。
We know that it has to be equal to less than 2, because even if we had absolutely no shielding at 2 all, the highest z effective we could have is 2, so it makes perfect sense that we have a z effective that falls somewhere in the middle of those two.
我们知道它必须小于,因为即使完全没有一点屏蔽,最高的有效的z是,所以我们得到的有效电荷量处于,两者之间就非常讲得通了,让我们来看看另一个例子。
