That means that it's harder to make a market for it, so the dealer wants to charge more.

这意味着,这样的品种市场很小,所以中间商要收取更多的费用

The examples we've done so far have been pretty straightforward, so we haven't needed to use formal charge to make this kind of decision.

我们之前做过的例题,都是非常简单直接的，因此我们还不需要,用形式电荷来做这种决定。

This can't make sense because the plum pudding model says you've got uniformly distributed charge.

这是讲不通的,因为布丁模型说的是电荷在里面均匀分布。

And the point that I also want to make is the way that they differ, z effective actually differs from the total charge in the nucleus due to an idea called shielding.

我也想指出的一点是它们不同的方式,有效的z事实上不同于原子核的，总电荷量,因为屏蔽效应。

What we need to do is get rid of the Coulomb tag that we have - that's how we measure our electron charges - charge, and so we use this epsilon nought quite often, this permativity constant of a vacuum to make that conversion.

怎么量度电子电荷,所以我们会经常用到,这个epsilon，nought记号,这是真空中的介电常数,我们还要指出,这个介电常数。
