This is just an equality. I have a constant pressure dH process. This term here is equal to zero.

这是一个等式，这是个恒压过程,这项等于零，这意味着。

Dictionaries are implemented using a magic technique called hashing, which we'll look at a little bit later in the term, which allows us to retrieve keys in constant time.

散列法的内容,此方法可以让我们在线性,时间内检索到键,因此字典的大小并不重要了。

b The repulsive term goes as some constant lower case b divided by R to the n. N is not the quantum number.

这种斥力很想一个固定的小写字母,被R到n分开的话，N不是量子数。

We can measure the heat capacity at constant volume, and now we have another term, and if we can figure out how to measure it, we'll have a complete form for this differential du which will enable us to calculate du for any process.

我们能够测量恒定体积下的热容，这里我们有另一项，如果能够知道怎么测量它，问我们就有了这个完整的微分式,就能够对任何过程计算。

Normally I couldn't do that Vdp because this term would have p dV plus V dp, but we've specified the pressure is constant, so the dp part is zero.

一般情况下我不能这么写,因为这一项会包含pdV和，但是我们已经假定压强为常数，所以包含dp的部分等于零。
