On a basis of the Kedem-Katchalsky formalism, the estimation method of the concentration boundary layers thicknesses (delta) in a single-membrane system containing non-electrolytic ternary solutions was devised. Square equation, 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 non-linearities are an effect of a competition between spontaneously occurring diffusion and natural convection processes. The obtained results of investigation suggest that in turbulent media separated by membrane the super-diffusion processes might also appear.
基于 Kedem-Katchalsky 形式理论，设计了一种用于估算包含非电解质三元溶液的单膜系统中浓度边界层厚度（δ）的方法。作为该方法基础的二次方程包含传输膜参数（L(p)、σ、ω）和溶液参数（D、C）以及体积渗透通量（J(v)）。这些值可通过一系列独立实验确定。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与自然对流过程之间竞争的结果。研究所得结果表明，在被膜分隔的湍流介质中也可能出现超扩散过程。
