摘要

从莱特希尔方程推导出了波在扰动介质中传播的方程。提出了所谓的微扰累积近似来求解该方程,并给出了倍周期分岔解。本文的研究结果有助于深入了解湍流的形成机制。

Bifurcation of Sound Waves in a Disturbed Fluid
An equation that describes the wave propagation in the disturbed medium was deduced from the Lighthill’s equation. The so-called perturbation-cumulative approximation was suggested to solve this equation and the period-doubling bifurcation solutions were given. The results obtained in this paper helps to provide insights to the mechanism of the turbulence formation.
