Right now it's empty, actually it's not quite empty, it has a pointer back to the class.

当我调用了这个类的，定义声明的时候，它在内存中的特定点。

At the same time, as I empty myself of a lot of my own focus on myself, it allows me to hear and pay attention to all the things that are around you.

我对自己做了清理,减少了自己的重视，这使得我能够注意到,身边的一些事情。

But unlike the case with boron where we had an empty p orbital, we're actually going to have an electron in the p orbital of carbon as well.

但和硼里面有个空的p轨道不同，我们实际上有一个电子,在碳里p轨道里也有电子。

Here I'll initiate the memo to be 0, or to be empty, rather, the dictionary.

在这里我会将memo初始化为，或者为空，作为记录字典。

if we move up one of our electrons into an empty p orbital, what were going to see is now we have three unpaired electrons that are ready for bonding.

教授：嗯，如果我们把其中,一个电子填入p轨道。

I'm going to give a name to that. And what you see there is I'm going to call divisors initially an empty tuple, something has nothing in it. Right here. And then I'm going to run through the same loop as before, going through this set of things, doing the check.

你们可以看到这里,我初始化一个空的元组,名为divisiors，这里，然后我会去运行,跟以前一样的循环，遍历这个集合内的东西,然后做检查，现在我要做的是，每次我找到了一个除数我要把它收集起来。

Keep in mind we do have this p orbital here and it's coming right out at us. And this p orbital is here, but it's empty, it doesn't have any electrons in it, that's why we don't have to worry about it in terms of getting our electrons as far away from each other as possible.

他们程120度角互相远离,这样它们离得最远，记住我们这里确实有个p轨道，它朝向我们，这里有个p轨道，但它是空的,里面没有电子,这就是为什么我们在考虑。
