我所研制生产的一批小型专用计算机,具有工作环境条件苛刻、可靠性要求高等特点。使用单位对这批产品提出的可靠性指标是99.8%,即相当于500台这样的产品中,使用时只允许一台失效;且要求产品必须通过高低温、冲击、振动等环境条件实验。为了达到这种高可靠性要求。就必须找出影响产品可靠性的主要环节和主要矛盾,分析并设法解决它们。
I developed and produced a number of small dedicated computers, with harsh working conditions, high reliability requirements. The reliability index put forward by the user for the batch of products is 99.8%, that is, equivalent to 500 such products, only one is allowed to fail; and the products must be tested under environmental conditions of high, low temperature, impact and vibration. In order to achieve this high reliability requirements. It is necessary to identify the main links affecting product reliability and the main contradiction, analyze and try to solve them.
