摘　　要：可靠性是电子设备的重要属性，可靠性试验技术是可靠性工程中的一个重要环节，可靠性外场评估试验是一些大型系统和设备定型设计中仅能采用的可靠性鉴定方法。文章介绍了电子系统和设备的可靠性参数与指标、外场可靠性试验的评估模型、可靠性数据的处理和解释，最后提出了有关电子系统外场可靠性评估的建议。Reliability is an important property of electronic systems and reliability test is an important process in reliability engineering. The outfield reliability evaluation is the only method of the reliability evaluation for some large systems. This paper specifies the reliability parameters, the evaluation model of the outfield reliability test, the processing and explanation of reliability data and provides the recommendation on the reliabitity evaluation of electronic systems in field test.
