摘　　要：运用积分变换的方法推导了超微带电极上同时受扩散、化学反应、电化学反应动力学控制的伏安关系，得到了前行化学反应、平行化学反应和后行化学反应的准可逆伏安方程，并列出了计算所得的典型伏安曲线．The theory of electrochemical processes controlled by diffusion,chemical reaction and electrode reaction occurring at ultramicroband electrodes are investigated by means of integral transformations. Multidimensional integral equations related to the E_qcirr,E_qcirr and c_rev E_q coupled with quasi-reversible charge transfer are obtained,the results we obtained as follows:For E_qC_irr process:where f(t,s) is the dimensionless electroactive species flux on electrode surface.The voltammogram can be calculated by numerical method,and the typical i-E curves are shown in this paper.
