摘要
本文在普通物理的层次上建立鱼洗的物理模型，应用柱面坐标的波动方程和模拟鱼洗的简化边界条件解出其自激振荡振型，与应用激光全息手段拍摄的鱼洗振型基本一致，亦与锤击实验中测得的鱼洗侧壁位移相符，从而初步揭示了鱼洗的喷水机理．
To explore the fish-basin's unusual water spouting phenomenon,a simplified model in university physics level is proposed.By using cylindrical wave equation with modified boundary condition,its self-excited vibration modes are obtained,which are in good agreement with those experimentally observed by laser holography and other means.Therefore,the mechanism of water-spouting effect has been preliminarily revealed.
