介绍了机载环境下紫外像增强管的几种典型早期失效问题, 对失效机理进行了分析, 提出了消除失效隐患的对策措施。实践证明, 采取对应措施后, 某型紫外像增强管的早期失效率显著下降。

Several typical early failure facts of ultraviolet image intensifier in the airborne environment were presented. The failure mechanism was carefully analyzed and the coping strategies for eliminating potential failure were introduced and used. The experimental results show that the early failure rate of the ultraviolet image intensifier has significantly reduced after countermeasures are taken.
