摘要:

计算机系统在实际工业现场中可能遇到的各种干扰和自身的随机性故障、现场恶劣的环境有可能使计算机系统发生异常，严重时，甚至使计算机系统出现工作混乱，酿成严重事故。因此应采用软件、硬件技术，在提高硬件系统抗干扰能力的同时，利用软件抗干扰方法设计灵活、节省硬件资源的特点，使计算机系统在错综复杂的环境里能保证程序稳定运行，提高系统的可靠性。介绍了计算机系统的软件、硬件可靠性技术，并从永久性故障和暂时性故障两方面对几种双机结构的可靠性进行了研究，证实了任务分担结构在提高计算机系统可靠性方面的优越性

Abstract:

The computer system is practically used in industry and meet all kinds of molestation and it sown random malfunction, Bad local circumstance may make the computer system crash, even the microcomputer system will be in a mess, causing severe accident. There- fore, should deal with the means of hardware and software, while to enhance the hardware system anti - interference ability, various anti - interference measures by the means of software with its design, the economical hardware resources, must be adopted to guarantee the safe and steady operation of the function in the bad circumstance, and enhances the reliability of the computer system, h~troduce the basic conception of two kinds of dependability technique of software and hardware in computer systems in detail, meanwhile analyze reliability of various double - computer models on permanent- malfunction and temporary- malfunction
