中文摘要：

基于经典流体的密度泛函理论并结合改进的基本度量理论，研究了受限于平行硬壁间的荷电硬球流体的平衡密度分布．通过对比有、无外电场时分子数密度分布的相应变化情况，分析了荷电硬球分子间的库仑排斥势能与场致势能间的竞争作用，研究了电场对于受限荷电硬球流体系统聚集态结构的影响．

英文摘要：

Based on density-functional theory and the modifi fluid, the equilibrium density distribution of charged hard-sph ed fundamental measure theory for the classical ere fluid confined in parallel plates was studied. By comparing the density distributions in the case of with and without applied electric field, the effect of the sphere fluid. The corresponding results can provide helpful clues for understanding quantitatively the properties of plasmas, ionic liquids and electrolyte solutions confined in mesoscopic scale.
