简介: |
Utilizing the brilliant solution by Onsager and Kaufman of the two-dimensional (2D) Ising model, a lattice gas model was constructed by Lee and Yang in 1952 for which the two phase region in its p-V diagram is analytically known. In the present work, we construct duplex models which have three phases, not just two, and for which the phase boundary in p-T diagrams and in p-V diagrams can both be exactly calculated. These models have two sublattices, and long range order form separately in the sublattices, creating a kind of partial order.
