Now we're not getting any volume at all.

Any idea why we're not getting any volume?

谁知道为什么没有声音

OK, now what we'd like to do is be able to calculate any of these quantities in terms of temperature, pressure, volume properties.

现在我们想要做的是能够利用,温度，压强和体积的性质,计算上面的物理量。

That is, in real life, the variables that you'd normally control aren't some combination of entropy and these variables, but really their temperature, volume and pressure, any couple of those, might be what you'd really have under experimental control.

在生活中，我们所能控制的,不是熵和其他变量的组合，而是温度，体积，压强，以及其中的两两组合,这些才是试验中所能控制的。

Negative volume doesn't make any sense.

负的体积也同样没有意义。

So this isn't the most useful form that we can have, but what we'll see shortly is that from this, we can then derive further criteria for essentially any set of variables or any set of external constraints, like constant temperature or pressure or volume and so forth that we might set.

所以这不是我们所能得到的最有用的形式，但是我们会很快看到，我们能够进一步推导出包含任意变量,或者任意约束的自发过程判断标准，比如说恒定的温度，压强,体积或者其他我们能够给出的约束。
