Abstract
In this paper,we study effects of permanent charges on ion flows through membrane channels via a quasi-one-dimensional classical Poisson-Nernst-Planck sys-tem.This system includes three ion species,two cations with different valences and one anion,and permanent charges with a simple structure,zeros at the two end re-gions and a constant over the middle region.For small permanent charges,our main goal is to analyze the effects of permanent charges on ionic flows,interacting with the boundary conditions and channel structure.Continuing from a previous work,we investigate the problem for a new case toward a more comprehensive understanding about effects of permanent charges on ionic fluxes.
