| Abstract: | Due to the difference of ultrasonic treatment's object and purpose, the applied ultrasonic biological-physical characteristic is different. Different physical characteristic has close connection with the working frequency, and so for the sake of the safety and reliability of the ultrasonic treatment equipment, one shold rightly select the ultrasonic frequency and solve the question of frequency automatic tracking. |
