摘要：

The integral equation method is an efficient, accurate numerical approach for computing transient current at planar microelectrodes. This method has been used to compute the diffusion-limited current at disk, band, and ring electrodes. In this paper we present a critical assessment of the influence of geometry on the behavior of the transient current. The disk and band geometries are shown to be limiting forms of the ring geometry. A normalization is introduced which permits differences in transient behavior at the various geometries to be ascribed to purely geometric factors. © 1990.
