摘要：

We are seeking a quantitative description of the measured impedance. In the potential domain that we have investigated so far, ie -0.1 < E(she) < 0.1 V, we find an appropriate description with a total of eight parameters and three equivalent models. Three of these parameters keep identical values for each model and constitute a ZARC element (R CPE parallel) which can describe correctly the dielectric properties of the metal-solvent interface. The other five are most probably simulating some properties of the bulk and of the measuring cell. We can interpret two of them as the solution resistance and the geometric capacitance of the cell. © 1990.
