| 摘 要： | 本文从声学原理出发,对H燃烧器声腔进行了分析,引出了等效阻尼的概念,从而简化了声振荡燃烧的控制方程并获得解析解。实验得出了频率在700～800Hz的强烈振荡曲线,表明H燃烧器用于研究推进剂低频燃烧特性是可行的,本文提出的方法能同时算得响应函数的虚、实部,这是传统的Culick理论所不及的。

| Abstract: | It has proved from theory and experiment that H-burner can be used to study instability combustion at a range of low frequencies. The sound wave equation can successfully solved by utilizing the concept of equivalent acoustic loss for pressure coupling. Not only the real component of response function but also its imaginary can be got with the help of the method proposed in this paper. |
