【摘要】 本文采用分子动力学模拟的方法研究了R1234ze(E)在288.15 K～338.15 K温度范围内6个不同温度点达到气液相平衡时的压强、气液相密度分布及气液界面性质。结果表明，R1234ze(E)的饱和压力与气相密度随温度的升高而增大，液相密度随饱和温度的升高而减小；气液界面厚度随饱和温度的升高而增加，说明高温状态下气、液相变的连续性要好于低温状态。更多还原

【Abstract】 In this paper, molecular dynamics simulation was used to study the pressure, vapour-liquid density distribution and vapour-liquid interface properties of R1234ze(E) when it reached vapour-liquid equilibrium at six different temperature points from 288.15 K to 338.15 K. The results show that the saturation pressure and vapour phase density of R1234ze(E) increase with increasing temperature, while the liquid phase density decreases with increasing saturation temperature.The thickness of the vapour-liquid interface increases with the increase in saturation temperature, indicating that the continuity of the vapour-liquid phase transition is better at high temperatures than at low temperatures.更多还原
