英文摘要：

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.
