关于风琴管问题的讨论

An Explanation of the Organ Pipe

在声场和喷流策动空气柱的相对简单的模型下,推导出风琴管内空气柱振动与外加气流和声场强度的关系,并用此方程对历史上瑞利与亥姆霍兹对风琴管发生原理的争论做出一定的说明与解释。

In the simple model which suppose that the air column in the organ pipe is pushed by the force which is caused by the sound field and the jet flow, we get the oscillate equation which is related to the jet flow and the sound intensity. And we also use that equation to explain the famous argument between Helmholtz and Rayleigh about the mechanism of the organ pipe in the history.
