对热声系统的起振与消振行为进行了实验研究 ,发现存在热声振荡滞后回路。研究了不同加热方式 (对称加热与单向加热 )及充气压力对滞后回路的影响 ,得出一些令人感兴趣的结论。
The experimental study on the start-up and anti-vibration of the thermoacoustic system shows that there is a thermoacoustic oscillation lag loop. The influences of different heating methods (symmetrical heating and unidirectional heating) and inflation pressure on the hysteresis loop are studied. Some interesting conclusions are drawn.
