本文提出一种由已知的两组元活度比函数l计算三元系中各组元活度的新方法,它只需要一组图解积分和一组图解微分的手续.为了进一步提高计算精度,还提出了应用精选的二元系热力学数据检验积分和微分运算结果可靠性的判别式.这种方法也可用于多元系.
Let τ be the function of activity ratio of two components B and C definedby given equation.A new method is proposed which can be used for calculatingthe activities of all the components in a ternary system A-B-C from the knownτ function only by using one set of graphical integration and one set of graphicaldifferentiation.In order to make the calculation with greater accuracy,the discrim-inant which can verify the reliability of integration and differentiation resultsrespectively by using the selected thermodynamic properties of binary systems arealso suggested.The method may also be available to multicomponent systems.
