Based on fractal theory, the density, the temperature, the pressure tensor, the local surface tension and fractional dimension number of liquid-vapor interface at equilibrium are obtained by the help of molecular dynamics simulation.

• 本文在分形理论基础上,采用分子动力学模拟方法研究了在平衡状态下的汽液界面参数,得了界面区内的密度、温度、压力张量、面张力和分维数的分布。
