摘 要：The gas-liquid phase coexistence in a two-dimensional Lennard-Jones system is investigated using Maxwell construction method together with molecular dynamics *** results of phase coexistence in different truncations of the potential are compared with data obtained from the literature,and the corresponding critical properties *** crossover from Ising-like to mean field behavior is observed and confirmed as the temperature approaches the critical point from *** simulations on systems with different sizes,we find that a finite size effect is more significant than those shown in most of the previous results,and a lower critical temperature is obtained when the full extent of this finite size effect is considered.
