摘　　要：综述了单气泡声致发光(SBSL)这种新奇的现象.由于SBSL现象在时间和空间的高度重复性,为实验研究气泡的运动特性和影响发光参数(含气量,水温,声压等)提供了可能.介绍了解释声致发光发原因的四种发光机理,并对各自的优缺点进行了分析.展望了单气泡声致发光现象在化学分析,医学检测等多个领域的应用前景.This paper reviews the novel phenomenon the s SBSL occurs accurately and repeatedly both in time and space behaviors of gas bubble in single bubblesonoluminescence and ingle bubble sonoluminescence（SBSL）. As ,it is possible to research into the dynamic some important parameters（gas concentration, water temperature, sound pressure）, which affect light emission of SBSL in the experiment. And the paper also introduces the four light emission mechanisms of sonoluminescence, analyzes their respective advantages and disadvantages and finally expects the prospects for the application of this sonoluminescence phenomenon in the fields of chemical analysis, medical detection, etc. in the future.
