0引言随着电子设备大量使用,严重的电磁干扰常常使电子设备不能正常工作。只有采用适当的屏蔽技术才是抗干扰的有效措施,才能提高电子设备运行的可靠性。下面我们就电场屏蔽和高、低频磁场屏蔽技术作一理论分析,并提出相应对策。1电场屏蔽1.1理论分析当干扰源产生的干扰以电压 0 Introduction With the extensive use of electronic equipment, serious electromagnetic interference often makes the electronic equipment can not work properly. Only by using the appropriate shielding technology is an effective anti-jamming measures, in order to improve the reliability of electronic equipment operation. Below we make a theoretical analysis of the electric field shielding and high and low frequency magnetic field shielding techniques, and put forward corresponding countermeasures. 1 Electric Field Shielding 1.1 Theoretical Analysis Interference sources generate interference when voltage is applied
