【 摘 要 】

Using the Kirkwood’s method, the free energy of a binary lattice solution consisting of two identical interpenetrating sublattices, such as a simple cubic lattice or a body-centered cubic lattice, was calculated up to the tenth order of thereciprocal of absolute temperature. Using this, liquid-liquid coexistence curves and critical solution temperatures for the binary lattice solutions were calculated to quantitatively investigate the effect of non-random mixing of molecules. And it was shown that thecoexistence curve of the simple cubic lattice solution was in good agreement with the Monte-Carlo computer simulation result.
