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。

The plastic constitutive model which involves DP yielding principle and relevant flowing principle was selected for high pressure conduction medium pyrophyllite.

文章为高压传压介质叶蜡石选择了一个塑性本构模型，它包括DP屈服准则和相关联的流动准则。

In this thesis, the first part is to design a differential pressure (DP) flowmeter.

本课题第一部分的任务是设计一种差压式流量计的差压发生器。

In other words, the order of taking the derivatives with respect to pressure and temperature doesn't matter And what this will show is that dS/dp dS/dp at constant temperature, here we saw how entropy varies with volume, this is going to show us how it varies with pressure.

换句话说,对温度和压强的求导顺序无关紧要,结果会表明,恒定温度下的，对应我们上面看到的，熵如何随着体积变化，这个式子告诉我们，熵如何随着压强变化。

What is dH/dT as a function, keeping pressure constant, what is dH/dp, keeping temperature constant?

恒定时偏H偏T是什么,温度恒定时的偏H偏p又是什么呢？,好的，让我们解决第一个问题？
