用多重平衡模型描述了不带电表面活性剂在水溶液中的聚集。使用该模型的光散射数据的分析，使单体物种的浓度作为总溶质浓度的函数获得。因此，平均聚集数和扩散系数可以分别从光散射和自由边界实验计算。一个简单的解释，这些参数的胶束水合作用和形状可能只进行在一个单一的胶束物种的情况下。结果表明，在278.2K时，N-烷基六氧杂环己二醇单醚（CNE 6）形成的胶束是单分散的。讨论了CNE 6化合物在胶束中的构型和胶束水合作用。
The aggregation of an uncharged surface active agent in aqueous solution is described in terms of a multiple equilibrium model. The analysis of light scattering data using this model enables the concentration of monomeric species to be obtained as a function of the total solute concentration. Consequently, average aggregation numbers and diffusion coefficients may be calculated from light scattering and free boundary experiments, respectively. A simple interpretation of these parameters in terms of the micellar hydration and shape may only be carried out in the case of a single micellar species. There is evidence to indicate that micelles formed byn-alkyl hexaoxyethylene glycol monoethers (CNE6) are monodisperse at 278.2 K. The configuration of the monomer in the micelles, and the micellar hydration are discussed for theCNE6compounds.
