摘要：

The case of a binary incompressible lattice mixture is treated using the Born-Green-Yvon (BGY) integral equation approach with the Kirkwood superposition approximation. Analytic expressions for DELTA-E(mix) and DELTA-A(mix) are derived without invoking the random mixing approximation. The BGY predictions for DELTA-E(mix) and DELTA-S(nc), the noncombinatorial contribution to the entropy of mixing, are compared with those of the lattice cluster (LC) theory of Freed and co-workers for mixtures in which at least one of the two components is a polymer.
