本文实验研究沿垂直方向强迫激励的圆柱槽中的一种新非传播孤波模式.对波形进行测量,并分别用双曲正割和余弦函数来拟合,结果表明前者和实验点吻合甚好.对波的振动模式分析表明,它不是圆柱槽中的一种纯模振动.我们用腊锥插入槽心,试图抑止水波的中间突台.在实验中也清楚地观察到被激发出孤波的振动滞后现象. In this paper, we study a new non-propagating solitary wave mode in a cylindrical tank forced forcibly in the vertical direction.We measured the waveforms and fitted them with hyperbolic secant and cosine function, respectively. The results show that the former is in good agreement with the experimental one .Analysis of the vibration mode of the wave shows that it is not a pure mode vibration in the cylindrical groove.We use the cone of cone to insert into the groove center in an attempt to restrain the middle abutment of the water wave.It is also clearly observed experimentally that the soliton Vibration lag phenomenon.
