摘要：
This work studies the effect of density-dependent potentials on the phase behaviour of fluids. For a particular class of density-dependent potentials, the equation of state has a simple relation to the equation of state of a reference fluid with a density-independent potential. This relation is illustrated by computer simulations of a fluid with density-dependent Lennard-Jones potential. Density-dependent potentials can be used in the Gibbs ensemble- this work presents the appropriate expressions for the pressure and chemical potential.
