| 摘 要： | 本文叙述了超声波对生物组织的微观作用。当超声波的强度超过了生物组织的临界空化阈值，可引起生物细胞的破碎。利用人体组织结构、密度的不同，其临界阈值不同，可实现超声波的可选择性破碎功能。介绍了提高换能器效率的方法和途径。给出了测试结果，减肥仪的整机效率约为73.6%左右。

| Abstract: | This article describes the micromechanical action of the ultrasonic wave on biological tissue. As the intensity of the ultrasound exceeds the threshold of acoustic cavitation ultrasonic liposculpturing maybe realize . Because of the different cavitative threshold in different tissues and structures of the human body, selective destruction occurs. High conversion efficiency of ultrasonic transdure is attamptel with the efficiency of our apparatus reaching 73.6%. |
