摘要
针对目前超声空化强度测量方法存在的测量过程复杂、测量设备昂贵等问题,提出了一种基于时差法的超声空化强度测量方法;介绍了该方法的测量原理,根据该方法设计了超声空化强度测量装置,并通过实验验证了超声波在液体空化时和未空化时的传播时间差与输入电功率在一定范围内成正比关系。
In allusion to problems of complex measuring process and expensive measuring equipment of current measuring method of intensity of ultrasonic cavitation,the paper proposed a measuring method based on time-difference method.It introduced measuring principle,designed a measuring device according to the measuring method,and verified the transmitting time-difference of ultrasonic in liquid with and without cavitations is proportional to input power in a certain range.
