So I'm so happy that it's finally time for us to go to the airport, get on a plane and just take off.

所以当我们终于到了机场，坐上了飞机并起飞后，我真是太高兴了。

Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.

平面上面的点的方法,也就是极坐标,上面那种方法其实是，如果你们喜欢我这么说的话,笛卡尔坐标表示法。

But if you go on a plane which is accelerating, you're no longer inertial.

但如果你上了一架加速飞行的飞机,你就不再处于惯性状态了

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 just to give you a sense, if you do a cross-cut of this, you cannot show it from this angle, but it should really be sort of a dumbbell shape with the nodal plane in between the two nuclei.

告诉你们这些就是给你们点概念，假如你们把他横切切开，不能从角度上展示，但它还是会保留几分哑铃的形态,以及在两核之间的节面。

That means, if you are going in a plane and you throw something up in the air, it seems to be going up and down to you.

也就是说,如果你在飞机中,你向空中扔出一物体,它也许会相对于你上下运动

So, let me get a little bit more specific about what we mean by nodal plane and where the idea of nodal plane comes from, and nodal planes arise from any place you have angular nodes.

关于节面的意义,或者节面概念的起源，让我们讲的更具体一点，节面起源于角向节点。

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。

And so it has what? In contrast to the sigma, it has a nodal plane containing both nuclei.

这是什么，和sigma相反，它是包覆在核上的平面电子云，有一个界面。
