摘要：

We present a framework for calculating the thermodynamic properties of each site on a chain molecule. This formalism provides a method for predicting the formation of microscopically-ordered regions within a macroscopic bulk phase. We apply the method to a simple mean-field lattice model of asymmetric dimer molecules both pure and in solution with hard dimer molecules and illustrate that local ordering can occur even in these very simple systems.
