摘　　要：利用有限分析法研究微盘电极上ＥＣ’伏安特性，计算结果表明有限分析法可用于微电极上均相化学反应伏安曲线模拟．提出了微盘电极上测定一级。Finite analytic numerical method(FAM) combining with conformal map has been used to study the diffusion problems coupled with homogeneous chemical reaction at microdisk electrode. In this report, we present the results of FAM approach to predict voltammetric curves in the presence first-order or pseudo first-order catalytic reaction at microdisk (EC'). The simulation allow the evaluation of the homogeneous chemical rate constant from experimental results obtained by linear sweep voltammograms. The results show the FAM is a quite flexible and accurate numerical method for dealing with electrochemical diffusion problem coupled with homogeneous chemical reaction. 
