All right, so the type of bond energies that we can go and look up in tables are individual atom bonds, H-H, F-F, and the like.

好的，键能的类型,我们能够在表中查到,都是独立的原子键，H-H，F-F以及类似的。

In contrast, if we talk about a double bond, what we're now talking about is having both a sigma bond and also one pi bond. And I apologize, I intended to set this up right before class, but that didn't happen today.

相反，如果我们讨论一个双键，我们现在讨论的是,一个sigma键和π键，抱歉，我应该在课前就把这个装好的，今天没装好。
