摘　　要：利用隐式差分法对管状电极对流扩散方程作了数值解，通过与平板电极电化学行为的比较，分析管状电极特性，讨论了管曲率对管状电极电化学行为的影响，并给出在管状电极中使用Ｌｅｖｉｃｈ近似的条件．The convective diffusion equation of tubular electrode was solved with the implicit finite difference numerical method. Comparing with the electrochemical behaviors of channel electrode, the behaviors of tubular electrode were analysised. The effects of curvature on the electrochemical behaviors of tubular electrode and the limit of applying Levich approximation to tubular electrode were discussed.
