摘　　要：针对实装屏蔽方舱的屏蔽特征与屏蔽效能测试要素,分析了GJB 6785-2009、GB 12190-2016等现行屏蔽效能测试标准应用于实装屏蔽方舱(屏蔽室)的局限性,并基于镜像原理、孔腔耦合理论,研究了产生局限性的因素,提出了相应的改进措施(抑制措施与修正因子),且经过实测验证了其正确性,旨在为相关标准满足实装屏蔽方舱的具体实施提供必要的技术支撑。In view of the shielding characteristics and shielding efficiency testing elements of the actual shielded square cabin,this paper analyzes the limitations of the current shielding efficiency testing standards such as GJB 6785-2009 and GB 12190-2016 when applied to the actual shielded square cabin(shielding chamber).Based on the mirror principle and the pore-cavity coupling theory,the factors producing the limitations are studied.The corresponding improvement measures(inhibition measures and correction factors)are put forward,and their correctness is verified by actual measurement,which provide necessary technical support for the implementation of the relevant standards to meet the requirements of the actual shielded shelter.
