On a basis of the Kedem-Katchalsky formalism, the estimation method of the concentration boundary layers thicknesses (delta) in a single-membrane system containing binary solutions was devised. Mathematical formula, which is a basis of this method, contains transport membrane (L(p), sigma, omega) and solution (D, C) parameters and volume osmotic flux (J(v)). These values can be determined in a series of independent experiments. Calculated values (delta) are nonlinearly dependent on concentrations of investigated solutions and membrane system configuration. These nonlinearities are an effect of a competition between spontaneously occurring diffusion and convection processes.
基于 Kedem-Katchalsky 形式理论，设计了一种估算包含二元溶液的单膜系统中浓度边界层厚度（δ）的方法。作为该方法基础的数学公式包含传输膜（L(p)、σ、ω）和溶液（D、C）参数以及体积渗透通量（J(v)）。这些值可通过一系列独立实验来确定。计算得到的（δ）值与所研究溶液的浓度和膜系统构型呈非线性相关。这些非线性是自发扩散和对流过程之间竞争的结果。
