The temperature scale that turns out to be well—defined and ends up giving us the concept of an absolute zero is the ideal gas thermometer.

理想气体温标它有精确的定义，并能引出绝对零度的概念。

We started out with four variables; the temperature, the pressure, and the components in the composition in the liquid phase and the composition in the gas phase.

我们一开始有四个变量：，温度，压强，某个组分在液体中的比例，和它在气体中的比例。

At this temperature, atoms of gas fuse, or combine together, and give out enormous amounts of energy.

在这温度下，气体的原子熔化，又或者融合在一起，便发出巨大的能量。

And that will end up winning out at basically any realistic temperature where the stuff really is a gas.

在体系仍然处于气体状态的温度下,熵战胜了能量。

But now, so this is where the refrigeration comes in. So if you take a gas, and you're below the inversion temperature and you make it go through this irreversible process, the gas comes out colder from that side than that side.

这就是冰箱的原理,如果在低于转变温度,的情况下我们将气体经过,这个不可逆过程,气体出来的温度将比这边低。

Or in many kinds of gas refrigerators where you push a gas through a nozzle close to room temperature, what you find is that the gas coming out on the other side under lower pressure is cooler than the gas that went through on the other side.

或者在很多种压缩气体式冰箱中,你让气体通过接近室温的管口,你会发现从压力低的一边,出来的气体比通过,另一边的气体更冷,真正的冰箱实际上通过。
