综述了气道结构和柔性管道响应于气流的自激振荡。这些结构包括肺深处的微小气道，在用力呼气结束时引起喘息。一个铜管乐器演奏者噘起的嘴唇。其他会振动的呼吸道结构包括声带（以及与之对应的鸟类鸣管）和打鼾者的软腭。这些生物的情况下进行比较与实验和理论的自激振荡的柔性管输送流的实验室工作台上，特别是参考那些观察处理的情况下，管壁的惯性是占主导地位的。在每一种情况下，都试图总结目前的理解状态。最后，确定了一些突出的挑战。(C)2008 Elsevier B.V.保留所有权利。
The self-excited oscillation of airway structures and flexible tubes in response to flow is reviewed. The structures range from tiny airways deep in the lung causing wheezing at the end of a forced expiration. to the pursed lips of a brass musical instrument player. Other airway structures that vibrate include the vocal cords (and their avian equivalent, the syrinx) and the soft palate of a snorer. These biological cases are compared with experiments on and theories for the self-excited oscillation of flexible tubes conveying a flow on the laboratory bench, with particular reference to those observations dealing with the situation where the inertia of the tube wall is dominant. In each case an attempt is made to summarise the current state of understanding. Finally, some outstanding challenges are identified. (C) 2008 Elsevier B.V. All rights reserved.
