摘　　要：针对国内外标准中对混响室连续模式辐射敏感度测试方法的缺失,构建了混响室中辐射敏感度测试系统。通过对三种不同军用医疗设备进行试验研究,总结出一套重复性强的混响室连续模式辐射敏感度测试方法。将混响室两种工作模式测试结果进行对比,发现无论连续搅拌采用哪种搅拌速度,对于不同的受试设备,其测试结果均低于步进搅拌模式。Because of the lack of standard testing method, people seldom use mode-stirred reverberation chamber for radiated immunity of device. In order to obtain the testing method, this paper establishes the testing system. In order to find a testing method for radiated immunity with well repeatability, three different medical devices are investigated. The results between mode-stirred and mode-tuned are compared, which show that whatever rotated speed the mode-stirred is and whichever the medical equipment is, its results are lower than mode-tuned.
