摘　　要：研究了刚性管道中粒子在振动空泡的作用下移除的过程,振动空泡由一个55 V的低压电路产生。高速相机记录了空泡作用下粒子的动力学行为及空泡的形状变化过程,高速相机的帧率设为15 000 f/s。结果表明:粒子的移除速度受空泡产生的初始位置和空泡在管道中的轴向长度的影响。In the paper,particle was removed in the pipe by an oscillating bubble. The bubble was generated using a very low voltage of 55 V. The dynamic behavior of the particle and the shape change of the oscillating bubble were recorded using a high-speed video camera,and the images were captured at a speed of 15000 f /s（ frames per second）. The experimental results show that the velocity of the particle is dependent on the bubble initial position and the bubble length along the pipe.
