| Abstract: | Shielding is an important measure to restrain interference, at the same time,shielding effect is associated with earthing. The plank type shields, the electric cable shields and the box shields were analyzed emphatically. Through selecting different earthing locations and using the equivalent effect electric circuit, the optimum location for earthing was selected. At last,the principle of selecting proper earthing location was summed up. |
