大分子溶质的传递系数通常外推到无限稀释，以消除浓度依赖项的影响，对此没有令人满意的一般处理方法。一个简单的一般治疗的浓度依赖性效应可以得出，适用于限制浓度的情况下，电荷效应或其他形式的溶质颗粒之间的特定相互作用。导出的关系是相当的实际意义的天然和合成聚合物的尺寸和构象的表征。
The transport coefficients of macromolecular solutes are normally extrapolated to infinite dilution to remove the effects of concentration-dependence terms, for which no satisfactory general treatment has been available. A simple general treatment for the concentration-dependence effect can be derived, applicable to limiting concentrations in the absence of charge effects or other forms of specific interactions between the solute particles. The relationships derived are of considerable practical significance for the characterization of the size and conformation of natural and synthetic polymers.
