| Abstract | 近年来国内大型射电望远镜建设加速，超高电磁屏蔽技术的研究及其工程应用极其紧迫。本文从理论层面推导和分析了非互联状态多层屏蔽壳体屏蔽效能与层数之间的关系，并依据GB/T 12190电磁屏蔽室屏蔽效能的测量方法，建立了单层、双层、三层预测分析模型，采用优势主路径法预测分析了不同层数屏蔽体的屏蔽效能，通过与理论计算结果进行对比，验证了非互联状态多层屏蔽层数与屏蔽效能之间的关系，为大型射电望远镜超高屏蔽环境构建提供技术和理论支撑。 |
| Other Abstract | In recent years, the construction of large radio telescopes in China has been accelerated, and the project of ultra-high electromagnetic shielding technology should be extremely urgent. In this paper, the relationship between the shielding effectiveness of multi-layer shielding shell in non-interconnected state and the number of layers is theoretically deduced and analyzed. According to the measurement method of GB/ T 12190 electromagnetic shielding chamber shielding effectiveness, the single-layer, double-layer and three-layer predictive analysis models are established, and the shielding effectiveness of different levels of shielding is predicted and analyzed by using the dominant main path method, and the relationship between the multi-layer shielding level and the shielding effectiveness of the non-interconnected state is verified by comparing with the theoretical calculation results, which providing technical and theoretical support for the construction of ultra-high shielding environment for large radio telescopes. |
