That's where we're heading.

这才是我们的目标
But first we have to understand what quantum mechanics is.

但首先我们要了解量子力学
So here's the SchroDinger equation, ΗΨ=EΨ,

薛定谔方程为ΗΨ=EΨ
and we're talking about the time-independent

这里讨论的是与时间无关的薛定谔方程
SchroDinger equation,so time is not a variables,

即时间不是变量
and that means what we're talking about is stationary states.

这意味着我们讨论的是定态
We don't mean that the atoms aren't moving,

这并不意味原子不运动
but just that they're in a cloud and we're going to find

只是假设它们在电子云中
how is the cloud distributed.

且试图搞明白电子云如何分布
If a molecule reacts, the electrons shift their clouds and so on;

如果分子反应了电子云就会相应变化
it changes. We're not interested in reaction now,

目前我们不关心反应
we're just interested in understanding

我们只是想了解
