摘要
20世纪人类最杰出的成就之一是电子技术和信息技术。电子信息系统的可靠性对生产、生活乃至国家安全都产生了巨大的影响。对信息系统可靠性造成影响的主要原因之一是电磁干扰。随着电气、电子设备的大量使用,我们周围的环境中充满了各种频率的电磁波,这些电磁波对于电子设备而言都是潜在的干扰源。在这里,主要介绍一些关于地线所造成的干扰以及相应的抑制方法。电磁兼容技术是电子产品设计人员必须了解和掌握的基础性技术之一。
Electronic technology and information technology are one of the greatest succeed in twenties centrury. Electronic system＇s reliability has taken great influence in our lives and stfety of our country. One of the metal causes is the EMI. With the most use of the electronic equipment ,all kinds of elctromagnetic waves exist in our enviroment ,and the elctromagnetic waves are the unseen source of the EMI. Now ,I will introduce some interference about GND and solution. EMC Tecnology is one of the technologies known and mastered by us.
