s The study on the effect of ultrasound on the external absorbability of Epinepheius awoara shows that all the intensity and ultrasonic time of the ultrasound and the concentration of the immersed chloromycetin solution have the positive effect. Besides, the ultrasonic methods also have distinct effects on the external absorbability of E. awoara. Compared with the methods‘ultrasound after immerse’ and ‘continuous ultrasound’, the methods ‘immerse after ultrasound’ and ‘pulse ultrasound’ have the better effect on improving the external absorbability of E. awoara.
