Shen its action in ultrasonic and other methods combined with sterilization experimental research mentions the sterilization principle of ultrasonic wave: during transient cavitation of ultrasonic waves, local instantaneous high temperature and high pressure are generated to cause cell breakage and denaturation of bacterial proteins, and meanwhile, when cavitation bubbles collapse, great shear stress and jet flow are generated in a solution to destroy cell walls. Ultrasonic stable cavitation produces a flow of microacous in the surrounding liquid and cells, and even if cavitation bubbles do not break up the stress, the stress is large. W.L.Wybory observes that proper amount of power ultrasound can generate micro-sound flow in animal and plant cells to cause movement of cell tissues to generate vortex in animal and plant vacuoles to cause internal structural changes of the cells, and finally causes bacterial death. Ultrasonic cavitation generates free radicals: OH, H and oxidizing substances. These substances affect the pH of the solution and destroy the environment in which bacteria grow and the structure of cells, thereby causing the death of bacteria. When the ultrasonic wave is combined with other methods, more oxidizing substances are generated under the action of ultrasonic cavitation, and the death of bacteria is accelerated.
