摘　　要：在实验的基础上指出 ,声脉动的发生不仅取决于 Rijke燃烧器的结构及热源位置 ,还受到进口处空气流速、温度梯度和气体平均密度等参数的影响。当这些参数和脉动速度数量级相当时 ,稳定的声场强度随空气进口流速的增大而加强 ,该流速的确定同时还要考虑燃烧的完全性。WT5”BZ]In this paper,an experiment on a Rijke combustor shows that the occurrence of sound not only depends on the structure of the combustor and the location of the heat source,but also on the inlet air velocity,temperature gradient within the combustor and the average density of gas,etc.When the pulse velocity of these parameters have the same order of magnitude,the intensity of a stable acoustic field increases with the increment of the inlet air velocity.The copmpleteness of combustion has to be considered when the inlet air velocity is determined.To maintain a stable acoustic field,the intensity and the characteristic location of the heat source and the uniformity of the inlet air fluid field of the combustor must be satisfied.
