摘　　要：本文引入了一种适于二维电化学扩散问题研究的新的数值模拟方法[有限分析(FA)法],并对微盘电极上的二维扩散问题进行了研究.模拟了微盘电极上的可逆及准可逆过程的计时电流,并进行了实验验证,实验与模拟结果很好地相符.A new numerical simulation method--finite analytic (FA) method was introducedin this paper. The two - dimensional diffusion problems at microdisk electrode were studied and the reversible and quasi - reversible chronoamperometric responses were simulated. The experiments of reversible chronoamperomtry were carried out and the experimental results were in good agreement with the simulated ones.
