摘　　要：复杂温度场条件下声场固有特性的研究是设计相关声学抑制装置的基础。结合软件仿真结果,设计了常温及高温下声腔内的声场固有频率实验研究模型,并进行了测量分析。实验与仿真结果的一致性表明所开展的实验研究是科学合理的。The inherent characteristic study of sound field in complex temperature is the basis of designing acoustic restraining device. Combining with software simulation, an experiment model, in which the inherent frequency of the acoustic cavity in normal room temperature and high temperature is measured, is designed. The consistency between experiment result and simulation result indicates that the study on experiment in the paper is scientific and reasonable.
