Similarly, with the second hydrogen atom, we've got the nucleus in the middle, and the 1 s b wave function around it.

类似的，在第二个氢原子里面，我们在中间有原子核，周围有1sb波函数。

So, now I hope you have in your mind a picture of the way the Greek world had expanded by the time this wave of colonization was complete--pretty complete, sometime in the seventh century B.C.

希望现在你脑海中有一幅,那时候希腊世界扩张的地图,在公元前七世纪的某一阶段,形成了一个完整的殖民浪潮,相当完整

So we can draw that for 1 s a, we can also draw it for 1 s b, and what I'm saying for the molecular wave function is that we have the interference between the two, and we have a constructive interference, so we end up adding these two wave functions together.

所以我们可以对1sa画出它来，我们也可以对1sb画出它来，对于分子波函数我要说的是,它们两者之间会干涉，这里我们有相长干涉，所以我们得到的是波两个波函数加起来。

So they're the same shape, this is the shape of the orbital or the shape of the wave function, and we can call this either 2 p x a being combined with 2 p x b, or we could say since it's the same shape, it's 2 p y a being combined with 2 p y b.

它们形状是一样的，这是轨道的形状或者波函数的形状，我们叫它2pxa和2pxb结合，或者我们说因为它们的形状是一样的，它是2pya和2pyb结合。

pxa So what happens when we add a 2 p a and we subtract from it a 2 p x b, or the same with a 2 p y a subtracting a 2 p y b, is that we're actually going to cancel out the wave function in the center, so we now have 2 nodal planes.

当我们用,减去2pxb时，或者是2pya减去2pyb时，我们会消去,中间的波函数，所以现在我们有两个节面。
