Pressure volume(P V) relationship of rabbits femoral veins was measured and the microstructure of the veins was observed.

进行股静脉的压力-容积（P V）关系测试，并观察血管壁的显微结构。

And it was supposed that the influence of the pressure on the system is only effect upon the exess molar volume of the system rely on the relationship of Gibbs free enthalpy with the pressure.

根据等温时压力对体系自由焓影响的关系式，把压力对体系热力学数据的影响都归结为对体系中各组元偏摩尔体积的影响。

It is based on the relationship between the volume pulse blood and pulse pressure.

仪器的原理是基于容积脉搏血流与脉搏压力存在一种相关关系。

Eventually we want the same relationship in the pressure and volume.

我们需要的是,压强和温度间的关系。
