That is to say brick work in high temperature furnaces, maybe tiles on the Shuttle, to resist high temperatures because of the high internal bonding.
它在能够承受高温炉的温度,例如瓷砖,能够耐受高温,因为它们有强的内部键作用。
So we had two weeks like about... Three weeks ago, we had like a big heat spell.
所以我们已经有两个星期像这样了……三个星期前,我们有一个持续高温的时期。
What that means is we want to run the hot reservoir as hot as possible and the cold reservoir as cold as possible.
也就是说我们希望高温热源温度尽可能高,同时低温热源温度尽可能低,从原理上说。
Point number two is that ionic solids at high temperatures make ionic liquids.
第二点是离子固体,在高温下会变成离子液体。
Not so much here, but because I do Bikram yoga,
不常在这里。但是因为我练高温瑜伽,
Taq stands for thermos aquaticus, it's a marine micro-organism that lives near these hydrothermal events in the bottom of the sea and they live under very high temperatures and pressures all the time.
aq是"水生栖热菌"的简称,那是一种生活在靠近深海热液活动区的,海底微生物,它们长期生活在高温高压的环境中
And we had the similar statement by Kelvin about the heat engine that required that some heat gets dumped into a cold reservoir in the process of converting the heat from the hot reservoir into work.
相同的陈述,同样的有开尔文表述:,把热量完全从高温热源,转移至低温热源的过程中,必然有功的输出。
You couldn't just run something successfully in a cycle and get work out of it, using the heat from the hot reservoir, without also converting some of the heat that came in to heat that would flow into a cold reservoir.
如果一样东西在循环工作过程中,只有热从高温热源中流出,而没有热流入低温热源,那么此过程,不可能对外做功,不可能把所有热。
The whole thing is being powered by sending heat from the hot to the cold reservoir.
所要做的所有事情,就是把热量从高温热源输送到低温热源。
That is it. So you want high temperature bricks, what are you going to make them out of?
这就是它,因此你想要高温砖,你打算怎么做它?
The colder that cold reservoir is, the hotter that hot reservoir is, the better off we are.
低温热源温度越低,高温热源温度越高,效果就越好。
So the expansion against lower pressure draws less heat from the hot reservoir right.
所以压强较低时的膨胀,从高温热源吸收的热量更少。
So let's take our hot reservoir and draw it bigger.
这是我们的高温热源,把它画得大一点。
So the way I've got things written here, q1 Heat's flowing from the hot reservoir to the engine that runs in a cycle.
我把这些都这些这里,是正的,q1,is,positive,热从高温的热源,传到循环工作的热机,对外做功。
It's taking heat from the hot reservoir.
从高温热源吸取热量。
You add a special DNA polymerase called Taq polymerase And Taq polymerase is a polymerase that was identified, a DNA polymerase that was identified from an organism that lives in regions of the earth that are constantly at high temperature.
然后你加进一种特殊的,被称为Taq的DNA聚合酶,Taq聚合酶是已被鉴别出的聚合酶,这种DNA聚合酶是从一种生活在,地球上某些常年高温的区域中的,生物体内发现的
What's the temperature of the hot reservoir?
高温热源的温度是多少?
