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。
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 ideal gas constant doesn't change, temperature doesn't change, and so v we just have minus nRT integral V1, V2, dV over V.
理想气体常数不变，温度也不变，因此,是负的nRT，积分从v1到v2，dv除以。
OK, so this one means we keep y constant, and partial f over partial u with v held constant, similarly.
这个的意思是，保持y恒定，而这个的意思是，保持v恒定。
So mu, the chemical potential for these configurations, dA/dN is just dA/dN. With T and V constant.
那么μ，构型的化学势，就是。
