The results of the calculations of the equilibrium potential and surface charge distribution in a vesicle with radii r1=55 A and r2=100 A are presented. The calculations were carried out for the electrolyte concentrations 100 mM, 10mM, 1mM and 0.1 mM. The digitally obtained solutions of the Poisson-Boltzman equation for the case of spherical symmetry were utilized in the exact solution of the problem. The predictions of the exact solution differ significantly from these of the linear approximation in the range of low electrolyte concentrations. The influence of the membrane dielectric permeability on the charge distribution is negligible.
给出了半径为r1 = 55 Å和r2 = 100 Å的囊泡中平衡电位和表面电荷分布的计算结果。计算针对电解质浓度100 mM、10 mM、1 mM和0.1 mM进行。在该问题的精确解中使用了通过数字方法获得的球对称情况下泊松-玻尔兹曼方程的解。在低电解质浓度范围内,精确解的预测结果与线性近似的结果有显著差异。膜介电常数对电荷分布的影响可忽略不计。
