中文摘要：

针对高可靠、长寿命的航天电子设备的可靠性评估问题,从Bayes定理出发,进行了理论推导,提出了一种等效任务数折合算法．在此基础上,建立了一种基于电子元器件通用失效率的电子设备可靠性评估算法模型,并对一具体航天电子设备进行了可靠性评估．

英文摘要：

According to the Bayes theorem, the comprehensive reliability assessment of high reliable electronic products in astronautics is studied theoretically and a method for the number of equivalent tasks is given, A calculation method from the tested and applied parameters of components is put forward. Finally a practical example for a certain space electronic product is presented.
