摘要
超声波是频率高于2000HZ的声波,在传播过程中具有方向性好、功率大、穿透性强,会引起空化作用等特点。文章结合超声波原理及其在传播过程中特性,着重分析探讨了超声波在现代军事运用、医疗技术、生活服务业及一般工业的应用,并对其在未来的发展进行了展望。
The ultrasonic wave refers to the acoustic wave with the frequency of over 2000Hz . In the process of transmission , it is well known for some of its feature suchas good directivity , large power , strong penetrability , and easy for cavitation. Based on this , the present paper conducts a discussion on its application in modem military, medical treatment services and industry.
