摘要：

The nonuniformity of current density at inlaid disk electrodes leads to a spatial dispersion of the charging time "constant", which ranges from zero to 2RC where R and C are the overall resistance and capacitance. The consequences of this dispersion are difficult to evaluate exactly, even in the absence of faradaic processes, but a short-time treatment suggests that the effect may sometimes be important.
