A STUDY OF THE MINIMIM (OR MAXIMUM) POINT ON THE PHASE DIAGRAM OF TWO-DIMENSIONAL ALTERNATIVE BINARY SYSTEM
关于二维二元替换式系统相图的极值等浓度点的几点讨论

Starting with the equations of phase equilibrium curve for the Collins model of two-dimensional alternative binary system, we obtained the conditions which must be satisfied by the attractive interactions between the atoms to get the phase diagram with a minimum (or maximum) point. The obtained results show that, this point is unique, and the position of the point (zf, tf) changes with the percent age of 4-atom obviously.
