The long,thin fibers are strong, and can work well to reduce temperature changes.

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。
And so, again, we see a temperature increase, and we know the work, and the temperature increase, it's a constant pressure thing.
好,我们看到温度升高了,然后我们有做功量和温度的升高量,这是一个恒定压力下的值。
Avogadro was a professor of chemistry at the University of Turin who did a lot of work on gas laws, understanding the number of gas particles in a given volume at a given temperature.
阿伏加德罗是一个化学教授,在都灵大学,他做了很多关于气体定律的研究,了解气体微粒,在特定的容量和温度下的数目。
Enzymes work best, enzymes are proteins that catalyze chemical reactions and our bodies operate by elaborate networks of chemical reactions, When we're off from that temperature then they don't work properly.
举酶这个例子再好不过,酶是一种具有催化作用的蛋白质,人体依靠精密复杂的化学反应网络来运转,如果我们体温与之相差较大,这些酶就不能正常工作
The same temperature increase, work and heat, and we have a relationship between heat and work.
同样的温度升高,功和热,因此我们可以得到功和热的关系了。
The purpose here is to look at a series of processes in which temperature is held constant, and we're going to calculate how much work we get from allowing a gas to expand under various conditions.
目的是让大家了解一下,几个保持温度不变的过程,然后我们将计算,气体在不同膨胀过程中,的对外做功。
So delta u is just equal to the work but we also know what happens T2 because the temperature is changing from T1 to T2.
所以Δu等于输出的功,但我们也知道它会发生,同时我们知道温度从T1变到。
