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。
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。
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
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。
What's the temperature of the hot reservoir?
高温热源的温度是多少?
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。
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。
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
