摘　　要：构建了混响室和GTEM室中辐射抗扰度测试系统,对典型卫生医疗设备进行辐照效应实验.利用衡量2组变量之间线性相关程度的Pearson积差相关系数来评价2种电磁兼容测试场地的辐射抗扰度测试的相关性.并对2个测试场地测得的受试设备敏感阈值进行了线性拟合.结果表明:混响室不同工作模式和GTEM室的辐射抗扰度测试所得结果的相关系数均大于0.75,说明2种测试场地具有非常好的测试相关性.The radiated immunity testing system of electronic device in Reverberation Chamber and GTEM chamber are established.In order to obtain the correlation between the two electromagnetic environments,representative medical equipment is investigated in them.Pearson product-moment correlation coefficient is chosen to evaluate the correlation of the two EMC testing cavities.The obtained results demonstrate that no matter RC address mode stirred or mode tuned, its result and GTEM chamber＇s has a very good correlation which pearson correlation coefficient is no less than 0.75.
