摘　　要：本文分析了中国科学院国家授时中心六台铯原子钟 5年的数据 ,认为外界电磁干扰对 5 0 71A铯钟性能仍存在影响 ,因此 ,对钟环境进行良好的电磁屏蔽是减小这种影响的一种有效措施 ,应该进一步进行定量研究。The five years data of six cesium clocks in National Time Service Center of the Chinese Academy of Sciences has been analyzed, it indicates that the external electromagnetic field still has the influence on the performance of clock. Therefore, to weaken the influence, the approach of electromagnetic shield must be taken, it considered an effective method for it, so it is necessary to study quantitatively in the future.

关 键 词：电磁屏蔽 铯原子钟 电磁干扰 物理机制 频率准确度
