摘要：

The interfacial admittance at the needle peak contains a new element, dominant at low frequencies, owing to the growth and dissolution of patches of condensed film in the narrow region of potentials in which they coexist with areas not so covered. At sufficiently high adsorbate concentrations, the additional admittance can be represented by a series RC circuit in parallel to the usual desad admittance. Experimental results for tetrabutyl ammonium bromide in aqueous 0.5 M NaBr are reported; these can be represented well in terms of this model.
