中文摘要：
超声空化是声化学反应的主动力,采用水听器对超声清洗槽内的超声空化场进行定量测量,通过频谱分析对声场能量进行分离,并利用非线性能量来表征空化能量,再通过MATLAB 软件对测量结果进行三维重建,该方法同时具备了定量性和直观性两种优势.同时,通过图形用户界面（GUI）对程序进行封装,增强了该方法的可操作性.基于此方法,进一步研究了液体中超声空化场的三维分布情况,并对其分布规律进行了探讨,从而为声化学反应提供了理论指导.
英文摘要：
Ultrasonic cavitation is the driving force of sonochemical reactions.A hydrophone was used to quantitativelymeasure the ultrasonic cavitation field in an ultrasonic cleaning tank. The measurement results were furtherprocessed in MATLAB software for spectral analysis and energy separation. The nonlinear energy was selected to representcavitation energy and the 3D cavitation field was reconstructed through a graphical user interface （GUI） programmedand packaged by ourselves, which made this method more visual and operable. On this basis, the 3D distributionof ultrasonic cavitation field in liquid was measured and the distribution pattern was studied to provide theoreticalguidance for sonochemical reaction.
