三元系中两相区边界上活度之间的关系以及该关系与结线方位的依从性
摘要:
本文研究了三元系中两相区边界上某组元的活度与三个组元的活度积φ之间的关系, 并导出了表示上述关系的重要公式, 该公式是一个将各种类型的三元系两相区的公式都概括进去的普遍式. 同时本文还详细地分析了结线的方位对活度之间关系的影响. 又应用了θ函数克服沿两相区边界上积分中的困难. 此外还完善了Krivsky和schuhmann规则。

Relationships Between the Activities on Boundaries of Two-Phase Region in Ternary Systems and the Dependence of the Relationships on Direction of Tie-Line
Abstract:
Relationships between the activity of a certain component and the product of ac-tivities of three components, Φ, which may be the activity of the compound, on boundaries of two-phase region in ternary systems have been studied. An important formula expressing above mentioned relationships has been derived. It is a common expression which involves various kinds of formulae for two-phase region in ternary systems. At the same time, we analyzed in detail the influence of the direction of tie-line on relationships between the activities. A parameter θ is empolyed in order to overcome the difficulties encountered in integration in the two-phase region. In addition, we consummated Krivsky and Schuhmann's rule on the basis of certain results in the paper.
