通过使用罗森菲尔德密度泛函，我们确定了靠近平面硬壁的二元硬球流体的两个组分的数密度分布以及相应的过量覆盖率和表面张力。与已发表的模拟数据的比较表明，罗森菲尔德泛函，无论是其原始版本还是其复杂程度，都优于以前的方法，并且表现出与相应单组分系统研究中已知的相同的出色精度。
By using the Rosenfeld density functional, we determine the number density profiles of both components of binary hard-sphere fluids close to a planar hard wall as well as the corresponding excess coverage and surface tension. The comparison with published simulation data demonstrates that the Rosenfeld functional, both its original version and sophistications thereof, is superior to previous approaches, and exhibits the same excellent accuracy as known from studies of the corresponding one-component system.
