Abstract

In the present article, mechanistic equations for membrane transport of N + 1-component solutions have been derived. The major specific investigation result is the introduction - for ternary solutions - of two diffusion coefficients omega(d1) and omega(d2) for solutes, as well as two cross coefficients omega(d12) and omega(d21) for these solutes. The latter parameters may be treated as coefficients of interdiffusion. The expansion of the description of substance transport to include the N + 1-component solutions does not formulate any additional physical phenomena other than those which are formulated by the transport equations for three-component solutions.

摘要

在本文中,已推导了N + 1组分溶液膜传输的机理方程。主要的具体研究结果是,对于三元溶液,引入了溶质的两个扩散系数ω(d1)和ω(d2),以及这些溶质的两个交叉系数ω(d12)和ω(d21)。后两个参数可视为互扩散系数。将物质传输的描述扩展到包括N + 1组分溶液,除了由三元溶液传输方程所阐述的物理现象外,并未阐述任何其他额外的物理现象。
