摘要：An improved correlation to estimate the thermal pressure coefficients of liquids over a wide temperature range from the triple point to the critical point is presented: gamma = (0.569 R\b*) exp(b*\V), where b* is a substance-dependent constant whose value can be evaluated from one reliable experimental gamma value of from group contribution. The calculation shows that the precision of both methods is far higher than that of the hard-sphere method.
