So what we've discovered from this relationship dq that du at constant volume is equal to dq v.

从这个关系式里我们发现，恒体积时的du等于恒体积时的。

In this method, a constant voltage source (v) is placed in series with the unknown resistor (r) and an ammeter (IM).

在此方法中，恒压源(V)与未知电阻(R)和安培计(IM)相串联。

Time grating displacement sensor is working on theory of time-space coordinate transformation, which need constitute a moving coordinate with constant velocity V.

基于时空坐标转换理论而研制的时栅位移传感器实现了以时间测量空间，但关键是要构建一个以恒速V运动的坐标系。

A It tells me that the partial of A with respect to T at constant V is minus S. Right?

他告诉我们,在恒定体积下对温度的微分等于负S，对吗？

So the first path then, the first path, 1 constant volume constant V, so I'm going to, again, let's just worry about energy.

首先，是路径，等压过程。
