【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, onboundaries of two-phase region in ternary systems have been studied. An importantformula expressing above mentioned relationships has been derived. It is a commonexpression which involves various kinds of formulae for two-phase region in ternarysystems. At the same time, we analyzed in detail the influence of the direction oftie-line on relationships between the activities. A parameter θ is employed in orderto overcome the difficulties encountered in integration in the two-phase region. Inaddition, we consummated Krivsky and Schuhmann’s rule on the basis of certainresults in the paper.更多还原
