【Abstract】 The Faradaic admittance expressions for the electrode process with an electrochemical adsorbed intermediate are theoretically derived under the conditions where the fast step is partially reversible or completely equilibrious.The four equivalent circuits are,respectively,used to simulate the four of typical Nyquist impedance diagrams.In addition,the effect of the double layer capacitance and the relaxation time constant on the impedance diagrams is also investigated.更多还原
