| 摘 要： | The reductive perturbation method of multiple-scales is used to investigate the weak nonlinearmodulation of the stress wave on the wall of a fluid-filled elastic circular tube.In the case of a singlemode,the nonlinear Schrodinger equation which the wave amplitude satisfies and its envelope soliton so-lution of stress wave are obtained. |
