这个区域的大小可以按照函数需要而变。

This area can be any size needed by the function.

我们将使用这个函数检查源区域的每个部分，从而判断是否有运动。

We will use this function to check every portion of the source area for motion.

对这个圆形区域创建一个函数索引。

Create a functional index on the area of the circle.

Remember this is our bond axis here, and you can see there is this area where the wave function is equal to zero all along that plane, that's a nodal plane.

记住这是我们的键轴，你可以看到在这些区域,波函数在这个面内全都是零，这是节点面。

And in either case if we first talk about constructive interference, what again we're going to see is that where these two orbitals come together, we're going to see increased wave function in that area, so we saw constructive interference.

在任何情况下,如果我们首先讨论相长干涉的话，我们同样会看到,当这两个轨道靠拢的时候，我们看到这个区域有波函数增加，所以我们看到的是相长干涉。
