锯齿波从某一始点到某一终点沿着一条直线上升(或者下降)，在终点的时候它马上跃迁回其起始值。

A sawtooth wave rises (or falls) in a straight line from a starting point to an ending point, at which time it instantaneously jumps back to the starting value.

记住一个波会有，正的幅值和负的幅值。

Remember when we have waves we can have positive or a negative amplitude.

所以，不管我们讨论的，是哪种波，它们都有一些我们，能用到的共同的定义，其中第一个就是幅值。

So, regardless of the type of wave that we're talking about, there's some common definitions that we want to make sure that we're all able to use, and the first is amplitude.

youdao

So, for example, if we were looking at the actual wave function, we would say that these parts here have a positive amplitude, and in here we have a negative amplitude.

我们看，一个波函数,我们说，它这部分幅值，为正,这部分幅值为负，当我们看。

No matter where you specify your electron is in terms of those two angles, it doesn't matter the angular part of your wave function is going to be the same.

不论你将，这两个角度,取成什么值，波函数的角向部分,都是，相同的。
