This is what she wrote about landing in northern Canada and jumping out of the plane.

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。

The reason that I wanted to point out this nodal plane here is because this is why it is called a pi orbital.

我指出这个节面的原因是因为,它就是为什么这个叫做π轨道的原因。

Everybody and his pet dog is trying to get a seat on a plane out of Logan airport.

每个人和他们的宠物狗,都想获得罗根机场的飞机上的座位。

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。

And when we look at this, it's actually split by what's called a nodal plane, which is pointed out in light orange here on this picture, but what we just mean is that there is this whole plane that separates the two lobes where there is absolutely no electron density.

我们来看这里，实际上它被一个节面分开，在这图里用淡黄色表示，这意味着这个分开,两个叶瓣的平面上,是完全没有电子密度的。

So again, we can name these molecular orbitals and these we're going to call also to point out there is now a bond axis along this nodal plane, which is something we didn't see before when we were combining the s orbitals.

同样的，我们可以,命名这些分子轨道,这些轨道叫做-同样要指出的是,现在沿着键轴是一个节点面，这是我们讨论s轨道的时候,从没有看到过的。
