| 摘 要： | 高效的热声转换需要创造高阻抗的行波声场，为避免闭合回路产生的直流损失，可以利用驻波声场的某些特殊性质。通过对几种驻波声场的分析，提出了若干可能结构的串级热声发动机或者串级制冷机的工作流程，可在实际中工作获得高的热声转换效率，同时具有更简单的结构和更高的可靠性。

| Abstract: | Efficient thermoacoustic transportation and transformation processes require to create the traveling wave acoustical field with high impedance,so that large viscous loss by flowing can be decreased greatly However,a kind of time averaged mass flowing usually occurs in a looped traveling wave thermoacoustic prime mover or refrigerator,which leads to a great loss due to the convective heat transportation of the flowing Several schematics of possible cascade thermoacoustic engines proposed here might still have high thermodynamic efficiency and will be more reliable and simpler in structure |

| Keywords: | high impedance local traveling wave acoustical field standing wave cascade thermoacoustic engine and refrigerator |
