Particularly, if we took advantage of the fact that this is a virus that's easily transmitted orally and could you make a vaccine that would be effective orally as well, that would be a tremendous advantage, especially in children who don't like to get shots.
尤其是,如果我们可以利用这种病毒,很容易经口传播这一事实,制造出一种,可以通过口服而起到同样效果的疫苗,那么这将是一个巨大的飞跃,特别是对于那些不喜欢打针的孩子

z So, this is what we find the actual z effective is for an electron in the helium atom.
所以这就是我们得到了实际有效的,对于一个氦原子的电子。
-
But what's important is not where that most probable radius is when we're talking about the z effective it feels, what's more important is how close the electron actually can get the nucleus.
但重要的不是,最可能半径,当我们谈论它感到的有效电荷量的时候，更重要的是,电子实际上。

But what you should be able to do is take a look at a list of answers for what we're saying z effective might be, and determining which ones are possible versus which ones are not possible.
但是你们应该能够做到的,是看一下这个可能的,有效电荷量的答案列表，并且确定哪些是可能的,哪些是不可能的。
