That statement says, get the value of x, which is this link, and give z a pointer to the same place.

这个声明的意思是，取得x的值，也就是连接指向的值，然后给z赋予一个指向同样位置的指针。

You'll notice that there's a little bit of a difference in these equations here from the ones from the other day, which is that you have z squared value in there.

你们会注意到这里的方程,和我们那天的方程,有些小的不一样，这里有z平方。

So the value is z is 4, it's what I expect, right?

所以z的值等于？

And it turns out that if we have a, for example, for s, a very large z effective or larger z effective than for 2 p, and we plug in a large value here in the numerator, that means we're going to end up with a very large negative number.

结果是如果我们有一个，举例来说对于s一个很大的有效电荷量或者,比2p大的有效电荷量，并且我们将一个较大的值代入计算器，那意味着我们最后会得到,一个非常大的负数。
