摘　　要：针对热力系统中声耦合燃烧振荡问题,分析了强迫共振和热声自激两类声耦合燃烧振荡的机理,重点综述了热声自激振荡的若干驱动机制,并给出了防止声耦合燃烧振荡的措施。The mechanism of forced resonance and self- excited thermoacoustic oscillation are studied to understand the combustion oscillation in thermal systems. Mainly,the driving mechanism of self-excited thermoacoustic oscillation are analyzed. Some measures against acoustically coupled combustion oscillation are provided as well.
