摘　　要：通过对同一金属板屏蔽小室的三个不同门窗屏蔽效能的测试,得到了三个不同门窗的屏蔽小室在0.03kHz～10kHz和10kHz～1000kHz频带内的稳态屏蔽效能,结果表明虽然开窗后全钢板屏蔽小室的屏蔽效能会在局部区段有所下降,但带金属丝网玻璃窗的金属板屏蔽室也具有较高的屏蔽效能。Shielding effectiveness test of metal plate shielding cabin with three different doors in the frequency band from 0.03 kHz to 10 kHz and 10 kHz to 1000 kHz has been conducted. The results show that the shielding effectiveness of metal plate shielding cabin with silk screen window could also reach to high value though the window could lead to the fall of shielding effectiveness in part frequency band.
