You take your fuel, you heat it up again.
然后移开热源。

We use a liquid helium. And so in order to make a liquid helium, you can't take helium at room temperature and do this, because if you did, you would just heat it up, because the room temperature is above the inversion temperature, so Joule-Thomson would heat up the helium.
为了得到液氦,不能再常温,做这个实验,否则就是加热氦气，因为室温高于它的转变温度,所以焦耳-汤姆孙，实验会加热氦气。
-
The native structure is this double stranded structure here and if I heat it up slightly and I add some base, so under slightly basic conditions, these molecules will fall apart because you've created conditions where the hydrogen bonding is no longer favorable so they peel apart.
原始结构,在这里就是指DNA双链,如果我稍微加热,并且加入一些碱,在弱碱性的条件下,这些配对碱基会分开,这是因为在一定条件下,碱基对之间的氢键,不再稳定并且会断裂分开
-
Her face became purplish except for little, white marks over it that didn't heat up.
她的脸几乎变成了紫色，还有些白色的小斑点。

It expands. You change your constraints on your system, you heat it up some more, then you take the heat source away, and you put it back in contact with the atmosphere. And you cool it a little bit, change the constraints, cool it a little bit more, and heat, and you've got a closed cycle engine.
让它与大气接触冷却,改变约束，使它继续冷却，然后又再次加热,这就是循环热机，我们以前也研究过，更复杂的机器。
-
I can take a heat pack, like the kind you buy at a pharmacy. Break it up. It gets hot.
买来的热装罐在里面打破,它就变热了。
-
The stuff that's inside the reacting volume, and whatever's right around it there inside the big box, it's all going to heat up.
都会升温，对吧？,在反应容器里的东西,以及大箱子里的任何东西，他们都会变热。
-
And it's for that whole unit that you've got some heat capacity. How much heat does it take the warm the entire thing up or the insides of the thing up by a degree? It's that number right.
由这个单位你能知道,一些热容的信息，要让这整个装置,或里面放置的东西,升温一度需要多少热量？
-
If it does, then the whole thing will heat up, right?
如果是这样，整个这些东西？
