给出了胶体颗粒和长圆柱形孔之间静电双层相互作用的理论结果，其中允许胶体呈现孔内的任何径向位置。胶体颗粒被表示为具有给定表面电荷密度或表面电势的实心球体，或具有给定体积电荷密度的多孔球体，并且采用泊松-玻尔兹曼方程的线性形式。获得相互作用势能的解析表达式并用于计算平衡分配系数。
Theoretical results are presented for the electrostatic double-layer interaction between a colloid particle and a long cylindrical pore, where the colloid is allowed to assume any radial position within the pore. The colloid particle is represented as a solid sphere with a given surface charge density or surface potential, or as a porous sphere with a given volumetric charge density, and the linear form of the Poisson-Boltzmann equation is employed. Analytical expressions for the potential energy of interaction are obtained and used to calculate equilibrium partitioning coefficients.
