基于对OZ方程的渐近行为与Taylor级数展开的分析,提出了一个新的桥泛函,桥泛函被表达为间接相关函数的函数,Taylor级数展开的重整化导致了一个可调参数,通过将所提出的桥泛函与一个最近提出的密度泛函理论方法学,以及单个硬墙的sum规则结合,可以确定可调参数.所提出的桥泛函能预言如下非均一流体的密度分布:硬球流体接近一个硬墙与在球形空隙内,Lennard-Jones流体与缔合硬球流体在两个硬墙之内.理论预言与文献所报导的模拟数据符合很好.
Based on the analysis of the asymptotic behavior of OZ equation and Taylor series expansion, a new bridge functional is proposed. The bridge functional is expressed as a function of the indirect correlation function. The renormalization of Taylor series expansion leads to an adjustable Parameters, the tunable parameters can be determined by combining the proposed bridge functional with a recently proposed method of density functional theory and the sum rule for a single hard wall. The proposed bridge functional predicts the following heterogeneous fluid Density Distributions: Hardball Fluid Approaching a Hard Wall and Within a Ball Gap The Lennard-Jones fluid and associated hardball fluid are within two hard walls. The theoretical predictions are in good agreement with the reported simulations.
