| Abstract: | On the basis of the stability theory of system,the stability condition for the electrode process with electrode potential and several other state variables is that all the roots of the characteristic equation characterizing the system have negative real parts.Moreover,the stability conditions for the processes containing one,two and three state variables respectively other than electrode potential were determined in this paper.In addition,a theoretical treatment about linear problem and transient response occurring in AC impedance measurements was also carried out. |
| Keywords: | electrochemical impedance spectroscopy stability linearity immittance |
