摘要：

The theory of collection-efficiency measurements (under steady-state conditions) at double-channel electrodes has been extended to include the effects of homogeneous kinetics. In particular first- and second-order decompositions of the species electrogenerated at the upstream electrode have been examined. These problems have been treated numerically using the backwards implicit finite difference method. This theory is readily generalized to allow for more complicated homogeneous chemical reactions.
