热声谐振管是热声热机的关键部件， 它相当于一个发动机， 将热能转化为声能。对热声谐振管进行了实验研究， 并对其起振温度、频率、振幅、输出功率进行测量和分析。 The thermoacoustic resonator tube is a key component of a thermoacoustic heat engine, which is equivalent to an engine that converts heat energy into sound energy. The thermoacoustic resonance tube was studied experimentally, and its starting temperature, frequency, amplitude and output power were measured and analyzed.
