不过，要是我们仔细查看这些发表的数据，你会感觉这个分布图有些怪异：刚好小于0.05这个阈值的P值实在太多了。
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。

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。

It is this that allows us to do the trick of printing out the parameter "p" and then passing it to the "rest" function to continue the computation, seen here in the definition of the "Bind" method.
这样话，就可以让我们能取巧打印出参数“p”并接着把它传递给“rest”函数继续进行计算。

The results show that the group of nodal planes of pre shocks puts together comparably and identical with the fault of main shock, so do their P axes.
结果表明，前震的一组节面比较集中且与主震断层面大体一致，其主压应力轴也表现出相对的集中。
