摘　　要：对热声发动机中的工质粒子进行量子力学行为分析,得出粒子处在不同一维势场条件下时的广义量子热声发动机微循环分析模型;运用此模型推导出广义量子热声发动机的性能参数表达式。研究结果表明:要使热声发动机性能达最优,必须对声场进行控制,使其能够在回热器中建立起一维无限深的或谐振的势阱条件。The quantum mechanical behaviour of working fluid particles in thermoacoustic engine was analyzed,and a set of analysis model for generalized quantum thermoacoustic micro-cycle working in various one dimensional(1D)potential wells was established.The expression of performance parameters of generalized quantum thermoacoustic engine was derived from this model.The results show that to achieve the optimal performance of the thermoacoustic engine,the acoustic field must be controlled so that 1D infinite or resonant potential well condition can be established in the regenerator.
