摘要
依据鲁米诺增强声致发光原理,采用微光测量系统,对超声清洗槽内空化声场进行了测量,分析了声致发光强度与功率密度及驱动频率的关系.结果表明,当输入功率密度超过声致发光阈值时,液体中才出现声致发光现象;同一功率密度条件下,不同超声频率发光强度不同.
According to the principle of Luminol increasing sonoluminescence （SL）, the ultrasonic field in cleaning tank is measured with the glimmer measurement system and the relationship between SL intensity and both the power density and acoustic frequency is analyzed. The results show that only when the input power density exceeds the threshold value of SL intensity, SL will happen. Moreover, in the same power density, different frequency correspond to different luminous intensity.
