That is, most processes that we're concerned with, they'll happen with something held constant like pressure or temperature or maybe volume.

这句话是说我们所关注的大部分过程，发生的时候都是保持某个量为常数,比如压强，温度或者体积。

And we saw that in fact in this case delta S of mixing, we calculated it, saw that it is positive.

实际上如果我们计算气体混合过程中,熵的变化，我们会发现这个量是正的。

Now I am going to break this into elementary steps and look at the relative contributions.

我会把这整个变化过程化为几个基本的步骤,去考察每一步的变化量。

So more than doubling the risk can certainly site to the population Now these kind of results show how important it is to do studies that don't group everybody in the population together.

由图可见,发病率差异量超过一倍,这些研究结果表明,在研究过程中分组的重要性

It's the constant enthalpy process that we're looking at. This we can do experiments on.

是一个焓不变的过程,这个量我们可以做实验。

This depends on the path. It tells you right here the path is constant pressure. These don't depend on the path, right. V doesn't care how you v get there. u doesn't care how you get there.

这由变化的具体路径决定,这个小脚标表明过程是恒压的,这些量都与具体路径无关,即不管是通过什么路径使得体积变化为Δ

Here are humans who had to walk long distances potentially to find the food, kill the food at great risk to themselves; inspiring a cascade of physiological effects that have to do with fear and arousal and things like that, not to mention all the calories one would burn doing this kind of activity.

这些人可能需要走很远的路,去寻找食物,冒着巨大危险,杀死猎物,人们耗费能量以激活一系列生理效应,用以战胜恐惧,引发斗志,更不用说人们在狩猎的过程中,消耗的卡路里量了
