介绍了一种专用于瞬时故障环境的纠错方案；说明了它的体系结构及工作原理；介绍了该系统的工作过程。根据该系统的工作原理，建立了数学模型，计算了该系统的可靠性。把它与具有相同的参数的单机系统、三楼冗余系统的可靠性进行了比较，证明了该系统具有较高可靠性。 An error correction scheme devoted to instantaneous fault environment is introduced. Its architecture and working principle are described. The working process of the system is introduced. According to the working principle of the system, a mathematical model is established and the reliability of the system is calculated. It is compared with the reliability of the redundant systems on the third floor and the stand-alone system with the same parameters, which proves that the system has high reliability.
