Elemental Composition Method in Thermodynamics of Multireaction Systems （Ⅱ） Residual Properties, Property Changes of Mixing and Excess Properties Relations

摘要

Based on the concept of “element” and the fundamental thermodynamic principle,the relationships of the residual properties,the property changes of mixing,excess properties,fugacity coefficients and activity coefficients between the hypothetical solution of elemental species and the equilibrated solution of actual species were established.The hypothetical solution of elemental species provides a way of reducing the dimensionality of problem, simplifying the analysis and visualizing the phase behavior.
