摘      要：Thermoacoustic engine has been concerned recently because of its advantages of no moving parts and no pollution. A prime mover is built and its characteristics of onset temperature difference, frequency and output acoustic power are measured and analyzed. A thermoacoustic refrigerator driven by this prime mover had been tested. It may develop a temperature difference of 25 K across the regenerator and a lowest temperature of -8℃ was achieved with the frequency, input power and the static pressure 81.7 Hz, 800 W and 1 Mpa respectively.
