摘　　要：热声热机的相位和功流的分布对于负载匹配至关重要。在无负载和有负载两种情况下 ,对热声谐振管的声场相位和功流分布进行了测量 ,并与网络模拟的结果进行比较和分析。实验结果表明 ,相位的分布与驻波比、位置以及负载有关。The distribution of phase and acoustic power along the resonance tube is very important to the load matching.They had been measured respectively on condition that the prime mover was working without load and with load,and compared with the network computations.The result showed that they are dependent on the standing wave ratio,the location and the load.
