摘　　要：A series of oscillators of pH and conductivity in emulsion structure change were found from composition change and component substitution of triglyceride hydrolysis oscillator which had been discovered by the author.The experimental results show that without any chemical reaction there are still various oscillations 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 Marangoni effect due to component substitution.A series of oscillators of pH and conductivity in emulsion structure change were found from composition change and component substitution of triglyceride hydrolysis oscillator which had been discovered by the author.The experimental results show that without any chemical reaction there are still various oscillations in the inner diffusion of the emulsion.
