The potential difference across the cylindrical pore, scaled by the total potential difference Δϕ between the two sides of the membrane. Potential difference along the pore wall: ——— theoretical prediction Δϕc (34); – – – – Δϕc, 0 computed for εs = 0; ⋯ computed for εs/ε0 = 3.9. Potential difference along the pore axis: - - - - - - - Δϕc, 3.9 theoretical prediction Δϕx (48); – - – - – computed Δϕx, 3.9 for εs/ε0 = 3.9.
