摘要：

Description of a computerized, automated method to measure the interfacial polarization immittance of a Pt electrode in nonlinear range is presented. The classical three-electrode setup is used for measurements in conjunction with a special purpose software implemented on a Unix computer using C language. A collection of data at very low frequencies (below 2 Hz) and at high input intensities with various dc biases imposed on the input are presented to show the behavior of the interface in nonlinear range. The instrument also provides on-line harmonic analysis of the output signal, by calculating the first four Fourier series coefficients, in response to a pure sinusoidal input. © 1990 Pergamon Press plc.
