| 英文摘要: |
| In this paper，the amplitude-frequency characteristics of piezoelectric transducer
resonant network are analyzed，and implementation by use of the characteristics is described,
and frequency tracking experiments for the ultrasound handle of the ophthalmic
phaco-emulsifier of cataract are carried out. Experimental studies have shown that by using
amplitude-frequency characteristics of the resonant network, and the frequency tracking
method of ultrasonic vibration system is a simple, effective and feasible solution |
