KW - Ionic flows, permanent charges, flux ratios.
AB - <p style="text-align: justify;">In this paper, we study effects of permanent charges on ion flows through
membrane channels via a quasi-one-dimensional classical Poisson-Nernst-Planck system. 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 regions 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.</p>
