You take your fuel, you heat it up again.
然后移开热源。
So that's the important take-away message from this slide. If we think about these different types of lights, microwave light, if it's absorbed by a molecule, is a sufficient amount of frequency and energy to get those molecules to rotate. That, of course, generates heat, so that's how your microwaves work.
重要的信息,如果我们看看,这些不同种类的光,微波,如果被分子吸收,它的频率和能量可以,使分子转动,这当然的,会产生热量,这就是你们微波炉的工作原理。
You want to keep spinning your mandrel so that it doesn't melt off the rod and you're going to heat your bead so that it's tacky enough to roll onto the frit and pick up pieces of the glass."

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。
"It was pretty much of a shock when I got here. I mean,if you're going to talk to some of your friends about some of the stuff you saw -- and you can't describe the smells, the feeling of the heat on your body and the sweat running down your back.

"It was pretty much of a shock when I got here." "I mean,if you're going to talk to some of your friends of some of the stuff you saw and you can't describe the smells, the feeling of the heat on your body and the sweat running down your back, the smell of the pus that hits your nose of unwashed bodies in a closed room, the circulation, the smell of your own panic when you're not sure what to do" Other doctors in the film echo Dr.Krueger's sentiments.
