使用由塑料薄膜和不同浓度的 NaCl 电解质制成的人造膜，研究了膜/电解质系统的低频介电行为。观察并研究了与膜孔和膜渗透性相关的低频介电色散或弛豫。提出了定性解释。研究发现膜结构特征，如厚度、孔径和数量，对低频介电色散有显着影响，这表明低频介电测量在膜或组织相关领域的一些潜在应用。 (C) 1997 年学术出版社。
Low-frequency dielectric behavior of membrane/electrolyte systems was studied with artificial membranes made from thin plastic films and NaCl electrolyte of various concentrations. A low-frequency dielectric dispersion or relaxation, which is associated with membrane pores and membrane permeability, was observed and investigated. A qualitative explanation is proposed. Membrane structure characteristics, such as thickness, pore size, and number, were found to affect significantly the low-frequency dielectric dispersion, which indicates some potential applications for low-frequency dielectric measurements in membrane-or tissue-related areas.
