in order to predict reliability, a sound valve design must be backed up up by a stress analysis and functional qualification testing under critical operating conditions 为了预测可靠性,一个可靠的阀门设计必须通过临界操作条件下的应力分析和功能合格测试。
to predict reliability, a sound valve design, backed up by a stress analysis must be subjected to functional cycle testing under critical operating conditions 为了实现预期的可靠性,需要科学的阀门设计,建立在应力分析基础上,并在关键工作环境下进行功能性循环测试。
the predicted reliability parameters of non-repairable system and repairable system were strictly distinguished . the availability of repaired instrument was first adopted in the analysis software developing, and the results were given 对不可修系统与可修系统的可靠性预测结果作了严格的区分,首次在软件开发中考虑可用性概念,给出了可修系统在修复后的可用程度。
