In this paper the classification of the gravitational effects in a passive transmembrane transport is presented. Among these effects there are the flux (flux graviosmotic effect, flux gravidiffusive, current gravielectric effect) and force (pressure graviosmotic effect, pressure gravidiffusive effect, voltage gravielectric effect) gravitational effects. The pressure graviosmotic effect model equation in a single-membrane system is elaborated. In this system the flat, microporous and symmetric polymeric membrane (Nephrophan) positioned horizontally separated water and binary (aqueous glucose) or ternary (glucose-0.2 mole/l) aqueous ethanol) non-electrolyte solutions. The calculations of pressure graviosmotic effects for two (A and B) configurations of the single-membrane system were elaborated. In configuration A solution was placed in compartment below membrane and in configuration B--above membrane. These calculated results are interpreted in terms of the convective instability that increases the diffusive permeability coefficient of complex: boundary layer/membrane/boundary layer.
本文介绍了被动跨膜运输中引力效应的分类。这些效应包括通量（通量重力渗透效应、通量重力扩散效应、电流重力电效应）和力（压力重力渗透效应、压力重力扩散效应、电压重力电效应）引力效应。阐述了单膜系统中压力重力渗透效应的模型方程。在该系统中，水平放置的扁平、微孔且对称的聚合物膜（Nephrophan）将水与二元（葡萄糖水溶液）或三元（葡萄糖 - 0.2摩尔/升的乙醇水溶液）非电解质溶液隔开。详细计算了单膜系统两种（A和B）构型的压力重力渗透效应。在构型A中，溶液置于膜下方的隔室中，在构型B中，溶液置于膜上方的隔室中。这些计算结果根据对流不稳定性进行解释，对流不稳定性增加了复合物（边界层/膜/边界层）的扩散渗透系数。
