中文摘要:
      采用频率为1.1MHz的脉冲声波,在声强≤0.5W/cm2的条件下引发溶液中的声致发光,发现在脉冲宽度为200μs-400μs的区间内声致发光出现峰值。由于声致发光由超声波空化效应引发,因此,空化效应出现峰值。该实验结果不同于Hill和Flynn等人的实验结论。
英文摘要:
      Pulsed ultrasound of frequency 1.1MHz,sound intensity ≤0.5W/cm2 was used to induced sonoluminescence.It was found that the sonoluminescence peak appeared in 200μs-400μs. Because sonoluminescence was induced by cavitation,thus cavitation appeared a peak.The experimental results were different from Hill and Flynn s results.
