摘　　要：阐述了混响室性能评价方法、机械搅拌器的作用与工作原理。利用电磁计算仿真软件分析了“Z”型搅拌器的长度和折叠数目对混响室场强均匀性指标的影响。结果表明,在混响室内部空间允许的条件下,搅拌器投影长度越长、折数越多,对应的混响室性能越好。The evaluation method of the reverberation chamber performance and the function and principle of the mechanical stirrer are presented.The electromagnetic calculation simulation software is used to analyze the influence of the length and the number of folds of the Z-style stirrer on the uniformity of field strength in the reverberation chamber.It is found that the longer the projection length of the stirrer and the more the number of stirrer folds,the better the performance of the reverberation chamber under the condition that the space allows.
