摘　　要：A lot of potential oscillations across oil_water interface ahve been designed by using various surfactants and biological surfactants in the aqueous phase and various amino acids or even polypeptides in the oil phase (nitrobenzene solution). Effects of the reactant’s concentration and the reaction temperature on the oscillating parameters have been studied. The oscillating mechanism has been discussed, and a model fo the oscillating mechanism has been proposed which is proved qualitatively reasonable according to the simulation.A lot of potential oscillations across oil-water interface ahve been designed by using various surfactants and biolagical surfactants in the aqueous phase and various amino acids or even polypeptides in the oil phase (nitrobenzene solution).
