本文用缀饰原子方法解出四能级系统远红外激光增益系数的解析表达式。

In this paper, we use the dressed-atom approach to derive the analytical expression of the gain of a FIR laser with a four-level system.

我的方法的别称叫原子，而原子方法可以让你用简单的四步就将几乎所有的空间整理的干净整洁。

My acronym is ATOM and good ol' Atom allows you to organize pretty much any space using four simple steps.

So, we'll start by taking a look at constructive interference, and another way to explain this is just to say again, molecular orbitals are a linear combination of atomic orbitals.

我们先来看一看相长干涉，另外一个解释它的方法就是说，分子轨道是原子轨道的组合。

So, either of those ways of figuring this out is the first guess of what goes in the middle will work pretty well.

因此，用上述任何一种方法来初步,估计哪个原子应该在中间都是相当好的。

that's one way to think about it, and there's also another way, and this is the way that your book presents it. If you, in fact, have two of the same atom right next to each other, let's say you have a crystal, or let's say you're talking about a metal, what you can do is just look at the distance between the two nuclei, and split that in 1/2, and take the atomic radius that way.

这只是一种定义的思路，另外还有其它方法，也就是你们课本上的方法，如果你，事实上，有两个相同的原子彼此靠在一起，比如说你有一个晶体，或者说你讨论的是一个金属，你所要做的就是,看看这两个原子核之间的距离，然后将距离除以二，就得到了这个原子的半径。
