C.O.P.D.is a new name for emphysema and chronic bronchitis.

And I can give a name to that, so c p 1 and c p 2 are both going to point to that.

为这个实例分配了空间，现在它是空的,实际上也不完全是空的。

p2 It's taking the name p 1 and it's changing its value to point to exactly what p 2 points to.

我要把p1赋值为1,这个操作有什么用呢？,这个操作把p1这个名字的,指针的值改变让它。

Again, the name is very straightforward, it comes from 1 s and 2 p orbital, so it will be s p 2.

所以，如果我们杂化这三个轨道，我们最后会得到的是sp2杂化轨道，同样，这个名字是很直接的。

And again, this is between the p orbitals, these are not hybrid orbitals, so when we name this bond we're going to name it as a pi bond here, because it's between two p orbitals, and it's going to be between the carbon 2 p y orbital, and the other carbon 2 p y orbital.

同样，这是在p轨道之间的，它们不是杂化轨道，所以当我们命名这个键时,我们要命名它为π键，因为它在两个p轨道之间，而且是在碳2py轨道，和另一个碳2py轨道之间。

Why is this much nice? Well, that's a handy piece of code. Because imagine I've got that now, and I can now store that away in some file name, input dot p y, and import into every one of my procedure functions, pardon me, my files of procedures, because it's a standard way of now giving me the input.

为什么这样很好呢？,这是一段很好用的代码,因为想象下如果我有了这段代码,我能把它用某个文件名保存起来,后缀是。py，导入到所有的处理函数中,抱歉，我的处理文件,因为这是一个标准的输入方法。
