摘　　要：热声发动机是将热能转化为声能的装置,是一种与常规机械式压缩机完全不同的新型驱动器。它没有运动部件,采用惰性气体为工质,可利用太阳能、废热等低品位能源为动力,因此具有结构简单、无污染、寿命长等优点。文章回顾了热声理论研究历程,介绍了热声现象的基本原理,重点阐述了国内外行波热声发动机的研究进展,并对行波热声发动机的应用前景进行了展望。Thermoacoustic engine is absolutely a new type of engine compared with the conventional mechanical compressor, which can convert thermal energy into acoustic power. It can use low-grade energy such as solar energy and waste heat as driving force. Without any moving part and with noble gas as working fluid, it has many advantages over the traditional engines, such as simplicity, pollution flee, and long-lifetime.After a detailed review on the research history of thermoacoustic theory, the fundamental theories of thermoacoustic effect was introduced briefly; the research progress of traveling-wave thermoacoustic engine at home and abroad was stressly elaborated and its application prospect was also expected.
