The existence of two radii of each charged particle-a geometric and electrokinetic radii, is supposed. The mathematical relationship between them in the four possible combinations of an ion and its counterion is analyzed: (i) at equal geometric radii and, in absolute values, equal valencies; (ii) at equal geometric radii and, in absolute values, different valencies; (iii) at different geometric radii and, in absolute values, equal valencies; (iv) at different geometric radii and, in absolute values, different valencies. One of the equations worked out can be used to define the relationship between the geometric and electrokinetic radii of a polyion. All the equations are used in working out precise calculations.
假定每个带电粒子存在两个半径——几何半径和电动半径。分析了离子及其抗衡离子的四种可能组合中它们之间的数学关系:(i) 几何半径相等且绝对值相等的化合价;(ii) 几何半径相等且绝对值不同的化合价;(iii) 几何半径不同且绝对值相等的化合价;(iv) 几何半径不同且绝对值不同的化合价。推导出的其中一个方程可用于定义聚离子的几何半径和电动半径之间的关系。所有方程都用于进行精确计算。
