| 摘 要： | 讨论了运动回热器的泵热制冷作用，建立了运动回热器控制方程的解析解。根据由热声理论得到的回热器泵热作用判据，指出回热器的泵热制冷作用有流道上有截面分布，这个截在分布受回热器运动的严重影响；讨论了回热器运动的相位及振幅对其泵热制冷作用的影响，所得结论表明了热声理论对热式热机工程实践发展的重要指导意义。

| Abstract: | The Heat pumping effect of moving regenerator is discussed in this paper,It is shown that the heat pumping effect distributes differently cross the channel section of regeneratoraccording to the criteria of heat pumping based on thermoacoustic theory. The affect of the phaseand amplitude of the motion of regenerator on the heat pumping is also discussed. These resuItsprove that thermoacoustic theory are important to the development of regenerative refrigerator inapplication practice. |
