一部分波从所遇到的物体反射回来，形成一种信号，称为回波信号。

A portion of the waves is there reflected from the object encountered and forms what is referred to as the echo signal.

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。

So, first, if I point out when l equals 0, when we have an s orbital, what you see is that angular part of the wave function is equal to a constant.

首先，如果ｌ等于０,那就是ｓ轨道，你们可以看到,它波函数的角度部分是一个常数。

We looked at the wave functions, we know the other part of solving the Schrodinger equation is to solve for the binding energy of electrons to the nucleus, so let's take a look at those.

我们看过波函数，我们知道解,薛定谔方程的其他部分,就是解对于原子核的电子结合能，所以我们来看一看。
