It is a line drawing made out of aluminum wire that looks like a wavy net floating in mid-air.

Again we can look at this in terms of thinking about a picture this way, in terms of drawing the wave function out on an axis.

同样我们可以,用这个图像来考虑，从画轴上的波函数来考虑。

A horse-drawing carriage in snowfalls that cause tires stick out of control with drivers gently toddles the ground and makes a nice pattern of black and white. That's how it used to be done, because he's a myth maker.

比如一辆马车在雪地上前行，但车轮松动,使马车夫不得不在雪地里慢条斯理地行进,这样的黑白画面塑造了很好的形象,这是他以前的做法，因为他是个创造神话的人，他说。

It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.

它总是一个好的第一近似，因为在画路易斯结构的时候,你总需要一个起点，但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷，比如有一个正二，一个负二，还有一个负一1,在原子的各个地方，这应该就是在告诉你,或许还有一个更好的路易斯结构。

And again, I want you to have practiced drawing these out in the form you always need to start with the sigma and then write the number of the orbital.

同样的，我希望你们,练习画这种图,你总是要从sigma开始,然后写出轨道数目。

So, I think we're a little bit out of time today, but we'll start next class with thinking about drawing radial probability distributions of more than just the 1 s orbital.

快没时间了,但我们，在下节课会讲,1s轨道以外的,径向概率分布。
