| Abstract: | In the paper, by setting up the mathematic model of leaky electromagnetism from the shelter slit, calculating leaky electromagnetism in the shelter, the theoretic instruction of the sensor layout in the shelter is provided. By analyzing the factor of affecting sheltery efficiency, the measure of improving sheltery efficiency is put forword. By applying the measure in detecting sound system, the electromagnetic disturbance has disappeared. |
