So hopefully, the first experiment he did, which I know that they certainly did do was maybe it's just background noise, right?
做的第一个实验,我相信他们肯定,是这样做的?
How do we go from that experiment to H the terms that we're trying to get, these slopes.
我们怎样从实验得到我们想要的量?,记住,我们想要得到Δ
But before we give the reasons let's do an experiment of Mill's claim.
但在给出理由之前,先对穆勒的观点做个实验。
Because of that you can do the following experiment, and it's a simple experiment, it's simple to understand, but the concept is very important so I encourage you to think about it and make sure you understand it.
我们可以做一个实验,这是一个非常简单容易理解的实验,但是这个实验验证的概念非常重要,我希望你们能够仔细思考,并且能够掌握
Sam All right. So, we'll move this up to the front in just a minute, but I'm going to explain how this experiment works and we'll do the calculation first before the excitement breaks out.
好的,这是她的女儿,被背带背她在胸前,这是Patti,Christie博士,好的,我们等会,会把它移到前面,但我要先解释下。
OK, so now we're going to do the same kind of experiment, but irreversibly. An irreversible adiabatic.
现在来在,不可逆的条件下,完成相同的实验。
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。
