摘　　要：为了提高计算机控制系统的可靠性,构建了软件层基于非相似余度技术、硬件层基于相似余度技术的双机容错系统,并就其可靠性进行了分析说明。通过理论上的分析,论证了此方案在实际工程中是完全可行的。For enhancing the reliability of the computer system, this paper sets up the fault - tolerant dual computer system consisted of software layer based on dissimilarity redundancy technique and hardware layer based on similarity redundancy technique, and analytzes the reliability of this system. Through theory, the thesis demonstrates that this system can be applied to the practical engineering definitely.
