This has caused the blindness of the initial ultrasonic frequency determination in the existing ultrasonic biological treatment method, and further, the additional ultrasonic frequency analysis and determination form dependence. The actual working process is: use the treatment of a certain biological cell at different frequencies, compare and analyze the sub-bands, and obtain relevant data; in the future work, continue to use the data of the specific object to empirically determine the appropriate ultrasonic frequency. This is a customary practice. In essence, such a method cannot guarantee that the working ultrasonic frequency is the optimal frequency for the object, nor can it perform precise and fine frequency adjustments for different objects, and the accumulated experience is not the best process; in addition, the The method not only consumes a lot of manpower, financial resources and material resources in the initial stage, but also often requires observation, adjustment and maintenance during the use period.
