摘要：
It is demonstrated that the crossover between gas- and liquid-like regions on the phase diagram of the Lennard-Jones system occurs at a fixed value of the density divided by its value at the freezing point, rho/rho(fr)& nbsp;~& nbsp; 0.35. This definition is consistent with other definitions proposed recently. As a result, a very simple practical expression for the gas-to-liquid crossover line emerges.& nbsp;Published under an exclusive license by AIP Publishing.
