Abstract: In this paper,the thermal effect,mechanical effect,and cavitation effect of ultrasonic field were introduced in detail. It was pointed out that the researches on mechanism of polymers change in ultrasonic field were limited to macroscopic view at present,and micromechanism research should be emphasized in the future to make the mechanism of polymer change under ultrasonic radiation clearly.

Key words: ultrasounic field, polymer, mechanical effect, cavitation effect
