| 摘 要： | 本文利用Ｖａｎ Ｍｏｏｒｈｅｎ提出的平均处理法，从理论上分析了一维流管通道随时间变化和燃烧边界运动对燃烧室线性声稳定性的作用。得出结论是，空腔的瞬态扩大和边界运动平衡掉了一部分声能。

| Abstract: | In the present paper,the mathematical mean treatmentmethod is taken from Van Moorhem.By theoretical analysis,the linearacoustic stability for an one-dimensional flow channel is considered.Ithas been proved that the enlargement of the dimensions of the cavitywith time and the motion of the combustion zone boundary wouldbalance a part of acoustic energy. |

| Keywords: | chamber acoustic stability moving boundary. |
