摘　　要：根据鲁米诺增强声致发光的原理,应用微光测量系统,对超声清洗槽内的空化声场进行了测量,分析了声致发光的强度与温度之间的关系.结果表明,在输入功率和超声波频率不变条件下,液体温度从6～85℃上升过程中,声致发光强度开始时逐渐增大,后来逐渐减小,55℃左右时光强达到最大值.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 the intensity of SL and temperature is analyzed. The results show that under the condition of the same input power and frequency, the intensity of SL increases gradually when temperature is increased from 6℃ to 55℃, but it decreases gradually from 55℃ to 85℃. The maximum of SL intensity is at 55℃.
