摘要：

Quantitative experimental investigations of pattern formation at a liquid interface are described. The reaction studied is the photoreduction of Fe3+ in aqueous solution and the subsequent formation of Turnbull's Blue. Both the wavelength of the pattern and the time at which the break in homogeneity occurs have been studied as functions of the concentrations of the reactants and the viscosity of the solvent. Many of the features of the process are consistent with a mechanism in which autocatalysis is enhanced by double diffusion. Preliminary studies of pattern formation in the KI/starch/chloralhydrate system are also presented. © 1990.
