The concept of an association dependent hard sphere diameter is introduced as a means to obtain an accurate perturbed chain-statistical associating fluid theory (PC-SAFT) equation of state model for water. The new approach is demonstrated to be a step change in accuracy for the representation of pure water properties as compared with standard PC-SAFT applications. Extension of the approach to mixtures is discussed.

一种修正的扰动链统计缔合流体理论状态方程的水，其中包括与缔合相关的硬球直径

引入了关联相关硬球直径的概念，作为获得精确扰动链统计关联流体理论 (PC-SAFT) 水状态模型方程的一种手段。与标准 PC-SAFT 应用程序相比，新方法被证明是在表示纯水特性的准确性方面的一个阶段性变化。讨论了混合方法的扩展。
