摘要 基于描述超声空化的Noltingk-Neppiras方程,以超声外场的频率作为实验可调参量,研究了空化气泡半径随外场作用时间的变化规律,并分析了超声外场的衰减对气泡空化的影响. The correlations between the radius of bubble and stimulation time under different fre- quencies were investigated on basis of Noltingk-Neppiras equation. The influence of ultrasonic field attenuation on bubblers cavitation was analyzed.
