摘要：
The kinetics of condensation of uridine were investigated by the potential step technique. Complex transients are obtained as a function of the initial and final potentials. Analysis of the kinetic results provides evidence for the existence of two distinct metastable states from which the formation of the condensed film prevailing at more negative potentials can start. The supersaturations for the various nucleation and growth processes were established on the basis of calculated relative electrocapillary curves characteristic of die stable and metastable films involved in the transformation.
