| Abstract: | A hysteretic loop,a special loop due to the difference between the onset temperature and the damping temperature,is proposed in the thermoacoustic oscillation for the first time.It is confirmed by the experiments on a thermoacoustic prime mover with nitrogen as the working fluid.The influence of pressure and heating on the hysteretic loop is also investigated and some interesting results are presented. |

| Keywords: | thermoacoutic prime mover hysteretic loop thermoacoutic oscillation onset and damping |
