For instance, you want to know how much energy you're going toget out from doing this expansion.
比如，你想知道在这个膨胀过程中,到另一个平衡态的路径。
-
How much energy are you going to get out, and how far are you going to be able to drive a car with this expansion, let's say, so that's the problem.
你能获得多少能量，利用这次膨胀,你可以把你的车开出多远，比如说这就是问题所在。

It was not like they were giving them a great deal, this was part of constructing their own business expansion.
并不是良心发现，而是为了生意扩张。

And that created enormous challenges, of our capability and systems and process to deal with this tremendous growth and expansion.
这也为我们带来了极大地挑战，公司的能力和机制与,快速的成长和扩张不符。

And if you look at this series, the series log of one, what is the series expansion?
如果你们看这个式子，它的对数分之一，它的指数是多少？

Or was it 1840? Or was it really in the wake of the Mexican War when you get this massive expansion into the great southwest and the Mexican Session which we'll take up actually next week?
还是1840年,在墨西哥战争的前夕,美国大举扩张进入,广阔的西南部地区及墨西哥会议的召开,这些其实我们下周都会讲到
-
People never thought of insurance as the same as a bank, but since this is relatively recently-- that was only nine years ago--at this time, it means that we are now seeing an expansion of our banking system in the U.S.
人们从来不认为保险和银行是一回事,但是从那法案之后它们就是差不多的了,这只不过是九年前的法案,但是现在,这意味着在美国,银行系统得到了扩张
-
You're allowed Cv comes out here for this adiabatic expansion, which is not a constant volume only because this is always true for an ideal gas.
绝热过程写下,这个式子是因为它对理想气体都成立，并没有用到等容过程的条件,只用了理想气体的条件。
-
Real refrigerators actually work with liquids that go into gases so use the latent heat of the liquid, so it doesn't really work like the Joule-Thomson expansion. So this is real.
液体变成气体来工作,以运用液体的潜热，所以这不是,真正像焦耳-汤姆逊膨胀一样工作,这是真实的气体，不像焦耳。
-
T2 So this is an isotherm at some different temperature T2, a cooler temperature, because this was an expansion.
这个绝热过程的温度是,比T1低，因为这是个膨胀过程。
-
This one turns out to be the heat capacity, and this one turns out to be something that we measure in the Joule-free expansion.
其实，这就是热容，这是焦耳自由膨胀实验中,我们要测量的物理量。
-
So the Joule free expansion involves opening this valve and asking what happens when this gas moves into the other bulb or distributes between the two.
焦耳自由膨胀就是,打开阀门后的过程,气体从一个腔跑到另一个腔,并在它们之间平均分配。
-
This follows the arrival of the expansion of serfdom.
这是随着农奴制的扩张发生的
-
It turns out that this quantity here, which is called eta of J the Joule free expansion parameter, is not quite zero.
这个量后来被，称作焦耳膨胀系数,其实并不等于零。
-
The way I've got this drawn, the volume is going up in the process. It's an expansion.
像我画的图这样，这个过程中,体积是增加的，这是个膨胀。
-
And I have this adiabatic expansion where p external is really small.
这时的情况,跟理想气体的。
-
I've done some sort of expansion on this.
我做了某种膨胀。
-
Adiabatic expansion means you can't use this.
这与等容的。

In this class here, we're going to stick to one kind of work which is expansion work.
