All the energy that is inserted into this, which might be turbulence initially, becomes heat, or becomes -- it raises the temperature.

由振动引起的所有，进入系统的能量最后都变成了热，因此温度便升高了。

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。
