提出了一种定量理论，描述了含有一种以上分散物质的胶体系统的凝聚动力学。利用低表面电位的线性（debye - h<s:1> ckel）近似，导出了描述不同球形胶体粒子之间相互作用势能的一般表达式。已经定义了一个总体稳定比，它考虑了系统中相似粒子和不同粒子之间相互作用的可能性。利用线性近似所引入的误差已经根据它们对稳定比的影响进行了评估，并且发现误差相当小。这个理论被用来描述一个假设系统在各种条件下的行为。
A quantitative theory is presented which describes the kinetics of coagulation of colloidal systems containing more than one dispersed species. A general expression has been derived to describe the potential energy of interaction between dissimilar spherical colloidal particles, using the linear (Debye-Hückel) approximation for low surface potentials. An overall stability ratio has been defined which takes into account the possibility of interactions between like, as well as unlike, particles in the system. The errors introduced by the use of the linear approximation have been assessed in terms of their effects on the stability ratio, and found to be quite small. The theory has been used to describe the behaviour of a hypothetical system under various conditions.
