摘要
屏蔽是抑制干扰的重要方法。而良好的接地则是使工业控制机系统稳定运行、消除干扰的重要措施。屏蔽和接地两大技术之间的联系密切，如果应用得法，可以明显提高系统的抗干扰能力。论述了工控系统工程中使用屏蔽和接地技术的诸多要点。
The screening is an important way to restrain disturbance.And good grounding is important means to stabilize work of industrial control computer system and to obviate the disturbances.The screening antidisturbance techniques and the grounding anti disturbance techniques maintain close ties each other.The capability to restrain disturbances can be obviously improved if they are correctly applied in industrial control computer system.This paper introduces various main points to handle screening and grounding anti disturbance techniques in engineering.
