All right, so in terms of s p 3 hybrid orbitals, let's combine all four together on one axis, because this is what's going to happen in an s p 3 carbon atom.
对于sp3杂化轨道，让我们把4个结合起来，因为这是sp3碳原子中发生的情况。

But once in awhile, one of these plus twos comes in almost on axis, and it gets whipped around by the Coulombic repulsive forces.
但是偶尔一个带两个正电荷的粒子,以接近于轴的位置进入，会快速的移动到周围,由于库仑斥力的作用。

The first one will be above and below the bond axis is where we'll see the electron density, and the second will be perpendicular to that, so it will be a density in front of and behind the bond axis.
第一个是在键轴之上和之下,我们可以看到电子密度，另外一个垂直于它，所以在键轴之前和之后有电子密度。

If we have, coming along this z axis, another carbon atom, we can actually form one bond between the two carbon atoms there.
如果我们在z方向，有另外一个碳原子，我们可以在,两个碳原子之间形成一个键。

We said, "Let's take, for the simplest case that we can possibly imagine, namely a particle moving in one dimension along the x-axis with a constant acceleration a.

Let's say it's one year and I'm going to actually plot on this axis a person's income this year.
我们假设是一年,我用x轴表示,一个人今年的收入
-
There's not two bonds, that's one pi bond, and the reason is because it's 2 p orbitals coming together, and remember p orbitals have electron density above and below the axis, so when they come together, it kind of looks like one bonds, but essentially what we have here is one pi bond.
这不是两个键，这是一个π键，因为这是两个2p轨道组合而成的，记住p轨道在键轴之上,和键轴之下都有电子密度，当它们靠近时，这看着很像两个键，但本质上它是一个π键。
