在这项工作中，我们使用一个通用的表达式来准确地关联液体密度，蒸发焓，表面张力，和等压热容的饱和液体与温度沿着整个共存曲线。所使用的一般表达式对于四个热力学性质是相同的，并且使用临界值和三相点值作为参考。作为使用该模型的代表性例子，给出了一组22种纯物质的结果。我们发现，这个一般表达式与较小或类似的整体偏差的数据相比，其他已发表的模型，其系数的数量是相同或更大。(c)2010爱思唯尔有限公司版权所有。
In this work, we use a general expression to accurately correlate the liquid density, the vaporization enthalpy, the surface tension, and the isobaric heat capacity of a saturated liquid versus temperature along the whole coexistence curve. The general expression used is the same for the four thermodynamic properties, and uses both critical and triple point values as reference. As representative examples of the use of the model, results are given for a set of 22 pure substances. We find that this general expression correlates the data with smaller or similar overall deviations when compared with other published models whose number of coefficients are the same or greater.
