本文作者系美国麻省理工学院林肯实验室计算机部门的负责人,曾领导过几个大型数字计算机的设计、制造及维护工作。在工作中提出和发展了一套提高线路可靠性及进行边缘校验的方法。所设计的计算机使用时间占总时间95%以上,工作效率很高。本文较完整地介绍了这种可靠性技术。文中所举例子主要为计算机中电子管线路(晶体管方面叙述较简单)。但其原则及方法同样适用于其他类型的线路。 The writer is the head of the computer department at Massachusetts Institute of Technology’s Lincoln Laboratory and has led the design, manufacture and maintenance of several large digital computers. During the work, a set of methods to improve the reliability of the circuit and verify the edge was proposed and developed. The design of computer use time accounted for more than 95% of the total time, work efficiency is high. This article presents a more complete introduction of this reliability technology. Examples cited in the text mainly for the computer tube circuit (transistor narrative is relatively simple). But its principles and methods also apply to other types of lines.
