| 摘 要： | 介绍两种使用流体动力学实现声致发光的方法：刹管法和U管圆锥泡法.这两种方法的设备简单，操作方便，容易在普通物理实验中进行，所得结果和传统单泡声致发光有所不同.U管圆锥泡法创造了发光功率和单脉冲能量的新记录，并首次用条纹相机得到了时间分辨发射光谱.

| Abstract: | Two hydrodynamic methods to realize sonoluminescence are described, one using tube arrest and the other a conical bubble U tube. Both methods only require simple apparatus and are easy to operate, so they can be performed in any conventional physics laboratory. The experimental results obtained differ from those of traditional single bubble sonoluminescence. New records for the luminescence power and energy emission from single events have been created, and the first time-resolved emission spectrum of sonoluminescence has been obtained with a streak camera by the U tube method. |
