标题： Probability Distribution of the Quality Factor of a Mode-Stirred Reverberation Chamber

摘要： 我们基于假设搅拌效率完美的理想化随机腔场的集合分布，推导出任意形状的模式搅拌混响室的品质（Q）因子的概率分布、置信区间和统计量。 结果表明，Q表现出一个自由度由每次搅拌状态同时激发的腔模数量控制的 Fisher-Snedecor F 分布。 Q的最可能值介于其均值的 2/9 到 1 倍之间，也介于其渐近值（复合Q值）的 4/9 到 1 倍之间。 算术平均值被发现总是超过Q中心性的所有其他理论度量值。 对于矩形腔，在高度过调谐状态下，我们得到了已知的渐近Q值。 显示英文摘要

摘要： We derive a probability distribution, confidence intervals and statistics of the quality (Q) factor of an arbitrarily shaped mode-stirred reverberation chamber, based on ensemble distributions of the idealized random cavity field with assumed perfect stir efficiency. It is shown that Q exhibits a Fisher-Snedecor F-distribution whose degrees of freedom are governed by the number of simultaneously excited cavity modes per stir state. The most probable value of Q is between a fraction 2/9 and 1 of its mean value, and between a fraction 4/9 and 1 of its asymptotic (composite Q) value. The arithmetic mean value is found to always exceed the values of all other theoretical metrics for centrality of Q. For a rectangular cavity, we retrieve the known asymptotic Q in the limit of highly overmoded regime.
