提出了胶体粒子与长圆柱孔之间的静电双层相互作用的理论结果，其中胶体被表示为具有给定表面电荷密度或表面电位的实心球体或具有给定体积电荷密度的多孔球体。分析仅限于球面的轴对称位置，并采用线性形式的泊松-玻尔兹曼方程。得到了相互作用势能的解析表达式，并讨论了其在平衡分配系数计算中的应用。
Theoretical results are presented for the electrostatic double-layer interaction between a colloid particle and a long cylindrical pore, where the colloid 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. The analysis is restricted to axisymmetric positions of the sphere and the linear form of the Poisson—Boltzmann equation is employed. Analytical expressions for the potential energy of interaction are obtained, and application of these to the calculation of equilibrium partitioning coefficients is discussed.
