讨论了具有早期失效的敏感元件与传感器的可靠性分布，由此提出了如何确定早期失效和筛选时间，并给出了实用例子，为进一步确定可靠性指标提供了依据． The reliability distribution of sensitive components and sensors with early failures is discussed. Based on this, it is proposed how to determine the early failure and screening time, and practical examples are given to provide a basis for further determining the reliability index.
