摘要：

The transient diffusion-limited current at the ring electrode is calculated over significant time intervals and reaction rates for the full range of significant ring sizes using Danckwerts' expression [J. Galceran, S.L. Taylor, P.N. Bartlett, J. Electroanal. Chem. 466 (1999) 15]. The steady state current for a ring electrode for EC reaction for all reaction rate is also derived. Limiting case results are compared with digital simulation results and are found to be in good agreement. (c) 2006 Elsevier Ltd. All rights reserved.
