中文摘要:
      简单地介绍了声致发光现象以及研究这一现象的意义。在此基础上详细地介绍了液体中实现声致发光的实验装置及其工作原理,以及声致发光光强测量装置。较为详细地叙述了信号发生器、功率放大器、可调电感、谐振腔(压电换能器)、磁力搅拌器、数字电压表、光电倍增管及数字示波器等部件在实验中的功能和作用、具体操作方法和实验步骤。根据测量得到的实验数据总结了影响声致发光现象的主要因素,即实验环境温度、驱动声压信号频率及驱动声压大小等等。对实验过程中遇到的一些问题给出解决方案,并提出了改善实验仪器的建议。
英文摘要:
      The phenomena of sonoluminescence and the significance of studying this subject is introduced in this paper. In addition, the apparatus for observing sonoluminescence in liquid, its working principle, and the equipment for detecting the light intensity of sonoluminescence are explained. Also, the functions, the operation methods and the testing procedures for all devices in the experiment including signal generator, power amplifier, adjustable inductance, resonant chamber, magnetic stirrer, digital voltmeter, photomultiplier tube and digital storage oscilloscope, are described. According to the data measured, the primary factors affecting the sonoluminescence, such as the ambient temperature, the frequency of driving acoustic wave and the amplitude of the driving acoustic pressure are discussed. At the end, the solution to the problem one might meet in the operation processes and suggestion for improving the experimental devices are presented.
