摘要	According to the relationship of the transmission line model (CR circuit) and the fixed configuration model (QR circuit), the analytical method of electrochemical impedance spectroscopy is established, by which the effect of coating's thickness and its application are investigated. The results show that for intact coating the fitting stability of CR circuit is higher than that of QR circuit. As compared to the parameter of constant phase element Y(0), it is more regularity for the relationship of C(0) with the state change of coating due to uptake water. The parameters of A(1) and B(1) deduced from that can be used to evaluate the effect of coating thickness on barrier qualities. Moreover, within some range the logarithmic linear slope of parameter C(i) vs characteristic frequency f* is not effected by the thickness of the coating with incomplete barrier properties, and has a certain connection with the ratio between the relative increment of capacitance and that of resistance, which could be used to assess the change of adhesion between organic coating/metal interface, and the reason is given.
