摘　　要：基于经典密度泛函理论,研究了受限于球腔空间的荷电流体的单位面积压力分布.计算结果显示,增大体密度和升高温度加剧体系内部压力分布曲线的震荡趋势.与此相反,增大色散作用的截断半径和分子的荷电量削弱曲线的震荡趋势.所得结果可为理解和掌握受限流体的力学性质提供理论参考和线索.Based on the classical density functional theory, the pressure profile of charged fluid confined in spherical cavity is investigated. The calculated results show that increase of bulk density and temperature prefers to enhance the oscillation of the pressure profile in the system. On the contrary, increase of cut-off of dispersion and the charge carried by molecular tends to weaken the oscillation of the pressure profile. The results can provide useful reference and clues for understanding the mechanical properties of fluids.
