主　　题：standing-wave thermoacoustic engine activity criterion instability criterion onset temperature 

摘      要：Onset mechanism is one of the most fundamental issues in thermoacoustic ***,the onset conditions and the phenomena happening in the onset process have not been well explained *** this paper,a novel model based on the circuit network analogy is proposed to predict the onset temperature of a standing-wave thermoacoustic *** activity and instability criteria are proposed to be the onset criteria in the *** influences of the porosity of the heat exchanger and the stack,and the length of the resonant tube on the onset temperature are *** calculated results are in agreement with the experimental results,which indicates that the activity and instability criteria can be used to predict the onset conditions of a thermoacoustic engine.
