摘　　要：应用CST分析带有孔缝的屏蔽体的电磁耦合规律。对不同形状以及不同位置的孔缝对屏蔽体屏蔽效能的影响进行分析,并对电磁干扰对内置电路的影响进行了分析,利用外部电磁干扰对内置电路导线上的感应电压来分析电磁耦合对电路的影响程度。CST is applied to analyze the electromagnetic wave coupling mechanism in shielding bodies with apertures. The effect on the shielding body＇s shielding effectiveness of apertures of different shapes and at different positions is analyzed. The effect of the electromagnetic interference on the buih-in circuit is studied. The effect of electromagnetic coupling on the circuit is analyzed by the voltage of the buih-in circuit induced by outside interference.
