中文摘要：

机载救护设备电子信息系统具有设备种类多、数量多、耦合控制等特点，属于复杂电子信息系统。本文根据机载救护设备电子信息系统的可靠性要求，分析了系统组成与特点、寿命剖面、任务剖面以及单体设备可靠性指标。在此基础上进行了子系统和系统级别的可靠性建模与预计分析。计算结果表明，系统的设计及零部件选型可以满足可靠性要求。

英文摘要：

Featured with many equipment types, large equipment quantity and coupling control, the etectromc information system of aero-hospital medical rescue equipment belongs to complicated system. According to the reliability demands of the system, system constitution and characteristics, life section, mission section, relia- bility parameters of independent equipment are analyzed. Based on the analysis, the subsystem level and sys- tem level reliability modeling and prediction are built. Results show that the system design and the selection of parts and equipments can satisfy the reliability requirements.
