We want a relationship in p-V space, not in T-V space. So we're going to have to do something about that. But first, it turns out that now we have this R over Cv.
我们想要p-V空间中的结果,而不是T-V空间中的,因此需要做一些变换,先来看现在的关系,它跟R/Cv有关。

Scratch The syntax actually looks reminiscent to Scratch, where you have a puzzle piece reminiscent of this shape, but you have to say "if" followed by a space, followed by in parenthesis, the Boolean expression that you want to check -- more on those in a moment.

But we also know there needs to be space for other conversations. In fact I think many of the conversations are that they have started on the community action trip that they might take as they enter freshman year or the outdoor action trip or other informal ways of making connections.

And I don't quite remember from reading or from class how big these things are, well, it turns out -- and this is sometimes useful, later on more likely than now -- but C has a size of operator that takes an argument in parenthesis and it will tell you how much space is used to store that particular data type.
我不太记得类中的这些类型,是多大的,嗯,结果是--这个在以后比现在,可能是更有用的--不过C语言中有个sizeof的操作符,其中括号里有一个参数,它会告诉我们,要存储一个类型的数据,需要占用多大空间。
