摘　　要：声致发光是声空化过程中的一种特殊现象,是由于气泡崩塌时所产生的光发射现象。其所包含的物理机制对声化学、核物理、流体力学等方面的研究起着至关重要的作用。但目前对于声致发光过程中空泡内局部产生的高温、高压等极端物理条件的测量结果差值较大,仍未得到统一结论。因此,该文从多泡声致发光(MBSL)和单泡声致发光(SBSL)2个方面,综述了MBSL和SBSL的主要作用机理和区别,以及几种认可度较高的温度和压强的测量研究方法。Sonoluminescence is a special phenomenon in the process of acoustic cavitation,which is caused by the light emission caused by bubble collapse.Its physical mechanism plays an important role in the study of sonochemistry,nuclear physics,fluid mechanics and so on.However,at present,there is a large difference in the measurement results of extreme physical conditions such as high temperature and high pressure in the process of sonoluminescence,and a unified conclusion has not been obtained.Therefore,from two aspects of multi-bubble sonoluminescence(MBSL)and single-bubble sonoluminescence(SBSL),this paper summarizes the main action mechanism and difference between MBSL and SBSL as well as several methods for measuring temperature and pressure with high recognition.
