All right, then as I push through, I'm going to start with all of my gas on this side, and at the end I'm going to have all the gas on the other side.

好的，随着我的推动,刚开始这些气体全在这一边,到了最后，这些气体全在另一边。

Now, he knows that first step ought to be like this, but he's only human, so the first step is like this, and so is the guy on the other end on that side.

他的第一步应该是这样,但由于人防卫的本能,他的第一步会变成这样,对面部队相同位置的人也会这样

And so you feel helpless until you notice that there is, off to the right, a side track and at the end of that track, there is one worker working on the track.

你极为无助,直到你发现，在轨道的右侧，有一条侧轨,而在侧轨的尽头，只有一名工人在那施工。

We call that inversion because on one side you end up cooling if you compress.

因为在这个温度的一边,当你压缩气体时气体降温。

And on the other side of that temperature you end up heating if you compress.

而在另一边的温度上,压缩气体将导致升温。

So in this experiment here, delta p is less than zero. You need to have this whole thing greater than zero. So delta T is less than zero as well. So if you're below the inversion temperature and you do the Joule-Thomson experiment, you're going to end up with something that's colder on this side than that side.

所以在这个实验中，Δp小于零,这全部都大于零,因此ΔT也小于零,所以如果在低于转变,温度的情况下做焦耳-汤姆孙实验,最后的结果是,这边的温度比这边低。
