摘要：

The method of molecular dynamics is used to investigate the p, rho, T-properties and the structural characteristics of the Lennard-Jones fluid in the stable and metastable states in the liquid-,oas phase transition. The calculation results demonstrate the presence of phase separation in molecular models at close-to-spinodal supersaturation. The effect of the cut-off radius of the interparticle potential on the process of phase transformation is analyzed, and the position of spinodal of superheated liquid and supersaturated vapor is estimated.
