状态(曙光女神) 的一个方程适用因为制服和不一致的液体被使用密度坡度扩大建立,在哪个影响参数[(r) , T ] 被直接关联功能的使用获得。功能的理论(DFT ) 提供的密度阶段 equilibria 和界面的性质能在一个单身者以内在下面被调查的一个框架分子的参数设定。在批评区域内的阶段 equilibria 能被重正常化组理论(RGT ) 改进。然而,由 DFT 和 RGT 的界面的性质的修正是计算地困难的。在现在的工作,在的密度坡度理论(DGT )[(r) , T ] 当一个常数被用来在批评区域内为界面的性质与 RGT 结合,被对待。
An equation of state (EOS) applicable for both the uniform and non-uniform fluids was established by using the density-gradient expansion, in which the influence parameter x[ρ(r),T] was obtained by the use of direct correlation function. The density functional theory (DFT) provides a framework under which both the phase equilibria and interfacial properties can be investigated within a single set of molecular parameters. The phase equilibria inside the critical region can be improved by the renormalization group theory (RGT). However, the correction of interfacial properties by DFT and RGT is computationally difficult. In the present work, the density gradient theory (DGT) in which κ[ρ(r),T] is treated as a constant is used to combine with the RGT for interfacial properties inside the critical region.
