但是现在我就要告诉你们，门捷列夫发表了它，原子序数，我们之后会学到，那是很大的进步。

But right now I am going to give it to you as Mendeleev enunciated it. Atomic number, we will learn later, is the improvement.

So I differentiated this object, this is my first derivative and I set it equal to 0 Now in a second I'm going to work with that, but I want to make sure i'm going to find a maximum and not a minimum, so how do I make sure I'm finding a maximum and not a minimum?

这样我就对它求出导数了,这是一阶导数,令它等于0,一会我们就要计算了,但我先确定一下是最大值还是最小值,我怎么确定是最大值还是最小值呢
