The equation gives a good correlation for vapor pressures of pure solvents as well as P-V-T behaviors of supercritical carbon dioxide.
该方程较好地关联了纯溶剂蒸汽压及超临界二氧化碳的P-V-T关系；

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.
