摘要: By using the reductive perturbation method, the carrier wave modulation propagating in a weakly viscous fluid-filled elastic tube is investigated. It is shown that such a process can be described by equation Aτ+iBAξξ+iC|A|2A+DA=0 and the amplitude of envelope soliton will decrease as it propagates away.
