中文摘要：
为进一步提高热声发动机的声功输出能力并为驱动多负载做准备，提出了热声发动机声功的多路引出方案。实验中以氮气为工质，工作压力为2．4MPa，在热声发动机环路压比稳定在1．20的情况下，从环路声容和谐振管处同时引出声功，获得了389．95W的最大声功，11．3％的最大声功输出效率以及16．0％的最大声功输出炯效率，这比单独从环路引出的最大声功和效率分别提高了51．4％，24．6％以及19．4％。
英文摘要：
In order to increase the acoustic power output of thermoacoustic engine and prepare for multiple loads, multi-output method was proposed with which acoustic power with different qualities could be obtained simultaneously. With nitrogen of 2.4 MPa as working gas and pressure ratio near the compliance of 1.20, acoustic power was got from the compliance and the resonator of the thermoacoustic engine Simultaneously. The maximum output power, thermal efficiency and exergy efficiency reached 389.95 W, 11.3% and 16.0%, which increased by 51.4%, 24.6% and 19.4% respectively than those with single-output method. It provides reference for making gradational use of acoustic energy of thermoacoustic engine and driving multiple loads..
