【 摘 要 】

References(10)A theoretical equation for oscillation of chain bubbles was obtained by use of velocity potential. To examine theoretical considerations, experiments applying the pulse response method of sound and the floating bubble method were carried out. The numerical solutions were well in accord with the experimental results, and the validity of the theoretical considerations was demonstrated. The frequency of chain bubbles decreased with decreasing interbubble distance and with increasing number of bubbles in water.
