The output frequency of the atomic clock drifts slowly,called frequency drift,which is a majorfeature of the satellite rubidium (Rb) clock and determinesthe autonomic running duration of the satellite navigation system.Evaluation on Frequency drift of satellite rubidium clocks and analysis on factors contributing to frequency drift are carried out.Primary factors leading to frequency drift of rubidium clocks are pointed out and proposals aiming at reducing frequency drift are put forward.

众所周知，当电缆在恶劣环境下运行时，容易造成绝缘性能的劣化，而电缆附件(包括中间接头和终端)是电缆线路的薄弱环节，其绝缘屏蔽口处的电应力集中容易发生故障。有研究表明，对于高压电缆线路运行故障，约80％以上都是由电缆附件引起的。因此局部放电试验能够有效检测并定位电缆附件中的潜在绝缘缺陷,是电缆状态评估工作的重要组成部分.本文从电缆附件的制作过程和安装工艺,分析了电缆附件发生局部放电的原因,其次详细介

ZnO压敏电阻是金属氧化物避雷器(MOA)的核心器件.对ZnO压敏电阻老化劣化以及损坏模式的研究对MOA性能的改进具有重要意义.借助多脉冲平台,研究ZnO压敏电阻在动作负载以及不同多脉冲冲击源条件下的性能变化,结果显示:1)多脉冲作用下,金属氧化物均匀度不同会导致不同的破坏形式,贴片接触结构均匀度较差的金属氧化物主要发生贴片的融化剥落.热物理性能均匀度较差的则以压敏电阻体的热燃烧和粉碎性破裂为主.
