To clarify contributions to cellular transmembrane potential concentration potentials of phospholipid bilayer membranes and surface potentials of phospholipid monolayers were measured with respect to salt concentrations and various surface charge densities. For highly charged membranes of symmetrical surface charge density, it was found that the observed transmembrnae potentials are due mostly to the difference between the surface potentials on each side of the membrane. For uncharged membranes, it was found that the transmembrane potential is due to the ion diffusion potential across the membrane. Also discussed are ion permeabilities through the membrane in relation to transmembrane potential.
为了阐明对细胞跨膜电位的贡献，测量了磷脂双分子层膜的浓度电位和磷脂单分子层的表面电位与盐浓度和各种表面电荷密度的关系。对于具有对称表面电荷密度的高电荷膜，发现观察到的跨膜电位主要是由于膜两侧表面电位的差异。对于不带电的膜，发现跨膜电位是由于离子跨膜扩散电位。还讨论了离子通过膜的渗透率与跨膜电位的关系。
