With the help of Matlab software

movement curves of cell wall with initial radius varying between 1 μm and 50 μm were simulated at different acoustic pressure

and the change of internal pressure in cavitation under some special situations was visualized also.Meanwhile

occurrence of enormous partial pressures of cavitation bubble near collapse points was presented.In addition

the larger bubbles’ movement at different acoustic pressures was simulated.The simulated results show that with the increase of acoustic pressure

the expansion of bubble is more and more obvious and the pressure in the cavitation bubbles is decreased.With increasing in the bubbles radius

the amplitude of the cavitation bubbles expansion is decreased.With the large acoustic pressure and the small initial radius

the bubbles exist in a short time

on the contrary

they can stay a long time

where sometimes the bubbles not collapse but pulsate in the time.At last

the experimental simulation in water was conducted.The results are well in agreement with the simulated ones.
