| 摘 要： | 介绍了通过直接测量微型热声斯特林制冷机(MMTASR)填料等效流阻进而辨识MMTASR回热器的特征频率的办法.测量结果与实际的MMTASR系统的流放大因子和传送损失系数的最优频率范围进行了对比.结果显示一定结构的回热器填料的特征频率与系统的最优频率范围吻合较好,因此这种填料特征频率的辨识方法可以应用于实际MMTASR系统回热器填料的生产过程中的质量控制.

| Abstract: | Based on the method for directly measuring the effective resistance,the characte ristic frequency in the regenerator of the microminiature thermoacoustic-Stirli ng refrigerator was distinguished.The results measured were compared with the fl ux gain factor and transmission loss of the real system.The range of the charact eristic freguency was in agreement with the frequeucy of the system.So the metho d would be used to quality control for the characteristic frequency of the regen erator in production. |
