摘　　要：本文叙述了将IBM-PC机应用于工业控制时遇到的种种干扰问题,并就如何消除外部干扰在抑制干扰源、切断耦合通道、对接收器加以保护或使接收电路对干扰不敏感等方面采取的措施作了具体介绍。Some problems of interference existing on IBM-PC in process control are presented. To solvethese problems, such measures as eliminating external interferences suppressing interference sources, cutting off the coupling channels, pro-tecting the receiver and making the receivingcircuit insensitive to interference are introduced concretely.
