That's because to suggest -- just think of it - to suggest that Milton is relying on his memory as he composes so allusively and so dependently, in a lot of ways, so much of Paradise Lost - to say that is simply to say that the poem has been generated by Milton and not by God.

So here, I'm going to have delta H, is just the sum for all the products of delta heat of formation right? Here I'm going to put together all the products. So this is a positive heat of formation.
所以这里△H就是所有生成物的,生成热的和,对吧?这里,我要把元素组合成所有这些,生成物,所以这里是正的生成热。

So essentially, each of these orbitals come from linear combinations of all of the original orbitals, and it's hard to picture exactly how that happens, but one that you can at least start to get an idea is if you think about combining the 2 s and the 2 p z here, which is not quite accurate because of course, we're combining all of them.
本质上,这些轨道每个都来,自原来所有轨道的线性组合,我们很难想象这是怎么发生的,但你们可以至少有个概念,如果你们考虑2s和2pz轨道的结合,这当然是不太准确的,因为我们要把所有的都组合起来。
