So instead, these would be canceling out wave functions between the two, so we would end up with a nodal plane down the center.

相反，两者之间的，波函数会相互抵消，所以我们在中间会得到一个节面。

So even though we see a nodal plane down the center, I just want to really point out that it's only when we have a nodal plane in the internuclear or the bond axis that we're calling that a pi orbital.

虽然在中间有个节面，我想要指出的是,只有节面在核间轴,或者键轴上时,我们才叫它π轨道。

It was as if a mirror had been placed in the center of the plane to remind us all of our humanity.
