摘要: 建立了由AppleⅡ~+微机和自制的电化学接口仪组成的时域法电极阻抗测量系统。该测量系统以奇次谐波合成的伪随机白噪声作为激励信号,以FFT作为时频变换的工具,并采用了信号平均技术以提高信噪比。用该测量系统测量模拟电路和实际电化学体系,其结果分别与SOLARTRON1250频响分析仪和文献数据接近。最后还讨论了时域法测量电极阻抗的激励信号的选择、测量频率上、下极限和噪声影响等问题。

Abstract：An electrode impedance measurement system by time domain method has been set up, it is composed of an APPLE Ⅱ microcomputer and a self-made electrochemical interface. Pseudorandom white noise is adopted as the excitation signal. The signal average technique and FFT algorithm are employed in order to improve the ratio of signal to noise and the rate of transform calculation. The measurement system has been used to determine the impedances of equivalent circuits and real electrochemical systems. The results well agree with those obtained by SOLARTRON 1250 FRA and the data from literature. The problems about the selection of excitation signal, limits of measurement frequency and noise influence have been discussed.
