Abstract: A series of oscillators of pH and conductivity in emulsion structure c hange were found from composition change and component substitution of triglycer ide hydrolysis oscillator which had been discovered by the author.The experiment al results show that without any chemical reaction there are still various oscil lations in the inner diffusion of the emulsion. During the oscillatory process, periodic change of interface membrane in the emulsion could be obseved by a 100 × microscope. The oscillation phenomena have been briefly explained by Marangon i effect due to component substitution.

Key words: Oscillations, pH, Conductivity, Emulsions
