A STATISTICAL THEORY OF THE TWO-DIMENSIONAL ALTERNATIVE BINARY SYSTEM
二维二元替换式系统的统计理论

The two-dimensional alternative binary system is studied by using the Collins model. The free energy of the system is calculated. The equation of the solubility curve is given. Using the condition of phase equilibrium, the phase diagrams of the two-dimensional alternative binary system are obtained, Finally, a dicussion on the results are presented.
