One thing that I want to mention that is really important is once you have double bonds, what happens between those two atoms in the molecule is they can no longer rotate in relation to each other.
我要提醒你们的非常重要的一点事,一旦有了双键,分子中的两个原子,就不能相对旋转了。
If you've ever been using some program, you did something completely innocuous, pull something down from a menu, click a button, you didn't do anything wrong and yet all of a sudden the thing just starts hanging there or you get a little spinning beach ball or the hour glass or whatever it is.
如果你之前在用一些程序,做一些无伤大雅的事情,拉下一个菜单,点击一个按钮,你没有做任何错误的事情,突然间有东西开始一直运行,或者一个沙滩上的小球旋转,或滴漏或是别的什么。

一些信号控制一个用于,金属编码磁盘的旋转。
Actually, the view of vectors we take nowadays is that vectors are associated with a pair of numbers which, on the rotation of axes, transform like this.
实际上,今天我们讲矢量所用的观点是,矢量是和一组坐标值相对应的,在坐标轴旋转的过程中像这样变换
So if we say that l is just talking about our kinetic energy part, our rotational kinetic energy, and we know that electrons have potential energy, then it makes sense that l, in fact, can never go higher than n.
如果我们说,l仅仅是,描述动能项,我们的旋转动能,我们知道,电子有势能,所以可以理解,l不能比n高。
