So that you're not just handed something that's entirely new to you with no idea which direction to go, we actually do set you off on an appropriate path.

这样一来就不会因为面对完全陌生的东西,而不知何去何从了，我们真心希望能把你们带到正确的道路上来。

They thought, for example, if you could do something with one element, if you looked at an element very close to it, it would be similar enough that you could maybe replace it with that.

他们认为，比如，用一种元素可以做的，用它邻近的元素，代替它的位置,也应该能做到。

And if it returns a value, you've got to do something with that return value too, much like we did up here.

如果它返回了一个值，你便用那个返回值,做一些事情，就像我们刚在上面做的。

You will have to have a little more math, a little more physics to do that, but I am going to talk about something that you are familiar with.

你还需要学习再多一点的数学，再多一点的物理，但我将说一些,你所熟知的事。

The children don't know about that you can do something with the intent to deceive.

儿童并不知道,人们可以出于欺骗而去做某事

Well, it probably ends up having something to do with finance because as a poet you probably want to publish your poetry and you're going to be talking to publishers.

它很可能跟金融有关,因为作为一个诗人,你想要发表诗作,那你就得和出版商谈谈

Because once you actually push people,to pin them down, what do you mean by it,you end up with something that's either just not true, or not interesting,or not necessary, or not particularly unique to death.

因为你一旦逼问他们这到底是什么含义，得到的东西既不会是真实的，也不会是必要和有趣的，也不会是对于死亡来说独特的。

So, the point is whenever you have derivatives with something over dt, do not hesitate to cancel the dts This will be actually true as long as both quantities are vanishingly small.

关键在于,只要你推出的式子分母上有dt,不要犹豫,直接约掉,这个式子只在,两遍都是无穷小的情况下成立

So in this experiment here, delta p is less than zero. You need to have this whole thing greater than zero. So delta T is less than zero as well. So if you're below the inversion temperature and you do the Joule-Thomson experiment, you're going to end up with something that's colder on this side than that side.

所以在这个实验中，Δp小于零,这全部都大于零,因此ΔT也小于零,所以如果在低于转变,温度的情况下做焦耳-汤姆孙实验,最后的结果是,这边的温度比这边低。

So instead you'd have to maybe if you start with wavelength, go over there, and then figure out velocity and do something more like kinetic energy equals 1/2 n b squared to get there.

这时你要先从波长开始，到这，然后算出速度,然后像动能等于1/2nb平方得到这。
