But because we're now programming a computer at a lower level and because as we said last week, you really have to be precise and then careful to instruct this machine, this fairly dumb machine that will only do what you tell it to do very specific instructions, do we have to use a more precise syntax than just a puzzle piece might have previously allowed.
但是我们是要在电脑的低平台上编程不是吗？,那我们就要像我上周提到过的那样，一定要小心，小心，再小心地,操纵这台又聋又哑的机器,它只会根据你敲进去的,特定指令来做事，所以我们必须使用非常精细的语法,而不是模模糊糊，让人费解的概念。

-
So we have two electrons in our bonding orbital, but because we use the same rules to fill up molecular orbitals as we do atomic orbitals, so the Pauli exclusion principle tells us we can't have more than two electrons per orbital, so we have to go up to our anti-bonding orbital here.
所以在成键轨道上有两个电子，但因为我们用了和原子轨道时,用的相同的规则，所以Pauli不相容原理告诉我们,一个轨道上不能有两个以上的电子，所以我们需要填充到反键轨道上去。
