摘要
本文应用统计能量分析理论和富里哀变换,推导出了非保守面耦合平行板系统间的耦合损耗因子的计算公式,保守面耦合平行板系统间的耦合损耗因子的计算公式能直接从该公式简化得出。已经进行了一系列验证实验,在大多数情况下,其实验数据与理论计算值吻合较好。
Coupling loss factor is an important parameter for characterizing energytransmission between coupled systems in Statistical Energy Analysis.In thispaper,two coupled parallel plate systems are discussed.The formula for calcula-ting the coupling loss factor between two non-conservatively face coupled parallelplates has been derived,using Statistical Energy Analysis theory and Fouriertransforms.A series of experiments have been carried out for coupled parallelplates with various thicknesses.Agreement between the measured and calculatedresults is quite good in most cases.
