"It is a double track approach,of course, to have a very clear position on sanctions, not only on Security Council, but specific new measures from the European Union on the financial side - on the oil and gas sector, in all elements that can give to Iran a very clear message that they have to move and respond to the requirements of the international community."

You've got to put more pressure on one side than the other if you want to push that gas through the throttle, right? So this is where the time scale issue comes into play.
如果你想让更多的气体通过节流阀,应该使一边的压强,大于另一边，是吗？所以这就是,时间尺度发挥作用的地方。
-
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。
-
There is p1 sitting here, and all of the gas is sitting on that side of the plug.
所有的气体都在节流阀的这一边,在我们完成了实验之后。
-
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。
-
Then after we're done with the experiment, we'll have transferred all of the gas from one p2 side to the other. p1 here. p2 sitting here.
我们使所有的气体，从这边到达另一边,这里是P1，这里是。
-
Our piston on the right side here fully out, and the piston on my right side, your left side, fully inside. There's no gas p1 on that side here. So there's p2 sitting here.
左边的这个活塞完全在外面，而右边的左边的这个活塞完全在里面，这边没有一点空气,这边是P2，这边是。
