在系统合金科学框架中建立有关无序合金的平均摩尔性质(体积和势能)的函数.通过对这些函数进行推导,可以得到平均摩尔体积函数、偏摩尔体积函数及派生出与成分相关的函数.在组元的偏摩尔性质和平均摩尔性质之间的普适方程、差分方程、在偏摩尔性质和平均摩尔性质之间不同参数的约束方程和普适的Gibbs-Duhem公式.可以证明从合金平均摩尔性质的不同函数计算的偏摩尔性质是相等的,但总体来说偏摩尔性质不等于给定组元的平均摩尔性质,即偏摩尔性质不能代表相应组元的摩尔性质.通过计算Au-Ni系中组元的偏摩尔体积和平均原子体积以及合金的平均原子体积,证明所建立的公式和函数的正确性.
在繫統閤金科學框架中建立有關無序閤金的平均摩爾性質(體積和勢能)的函數.通過對這些函數進行推導,可以得到平均摩爾體積函數、偏摩爾體積函數及派生齣與成分相關的函數.在組元的偏摩爾性質和平均摩爾性質之間的普適方程、差分方程、在偏摩爾性質和平均摩爾性質之間不同參數的約束方程和普適的Gibbs-Duhem公式.可以證明從閤金平均摩爾性質的不同函數計算的偏摩爾性質是相等的,但總體來說偏摩爾性質不等于給定組元的平均摩爾性質,即偏摩爾性質不能代錶相應組元的摩爾性質.通過計算Au-Ni繫中組元的偏摩爾體積和平均原子體積以及閤金的平均原子體積,證明所建立的公式和函數的正確性.

In the framework of systematic science of alloys,the average molar property (volume and potential energy) functions of disordered alloys were established.From these functions,the average molar property functions,partial molar property functions,derivative functions with respect to composition,general equation of relationship between partial and average molar properties of components,difference equation and constraining equation of different values between partial and average molar properties,as well as general Gibbs-Duhem formula were derived.It was proved that the partial molar properties calculated from various combinative functions of average molar properties of alloys are equal,but in general,the partial molar properties are not equal to the average molar properties of a given component.This means that the partial molar properties cannot represent the corresponding properties of the component.All the equations and functions established in this work were proved to be correct by calculating the results of partial and average atomic volumes of components as well as average atomic volumes of alloys in the Au-Ni system.
