本文讨论了微带电极的计时电流、扩散层与时间的关系;研究了微带阵列电极的扩散层交叠情况及其对计时电流的影响;进而对微带阵列电极上电极间的屏蔽效应进行了研究,屏蔽效应与电解时间、电极间距离及电极宽度有关,用已有的实验结果验证了本文的理论分析. In this paper, we discuss the relationship between the chronoampere current of the microstrip electrode and the diffusion layer and the time. We also study the diffusion layer overlap of the microstrip array electrode and its influence on the chronoamperion. Then, the shielding effect between the electrodes on the microstrip array electrode The study, the shielding effect and the electrolysis time, the distance between the electrodes and the electrode width, with the existing experimental results verify the theoretical analysis.
