摘　　要：谱灯光抽运被动型铷原子钟具有长寿命、极低的随机频率漂移噪声和较好的短、中期稳定度等显著的优点,在卫星导航定位系统中有着广泛的应用。但是这种铷原子钟的准确度和长期稳定度较差,已经不能满足新一代导航定位系统的要求。离子阱汞离子微波(Hg+)钟已经达到了主动型氢原子钟的性能指标,与传统铷原子钟相比,具有更加广泛的应用前景。铷原子钟和汞离子微波钟有许多相同点和不同点,对两者差异性进行分析可以借鉴现有铷原子钟的研究,加深对汞离子微波钟工作过程的认识。本文对两者的原理和关键技术进行了比较分析,对汞离子微波钟的发展具有一定的借鉴作用。The lamp-pumped rubidium atomic clock has a wide range of applications in satellite navigation and positioning system.It has many advantages,such as long life,very low random frequency drift noise,good short and mediumterm stability and other significant advantages,but its accuracy and long-term stability are low.With the development of navigation and positioning system,the traditional rubidium atomic clock can not meet the new generation of navigation and positioning system.The microwave atomic clock of Hg+ion in ion trap has realized the performance index of hydrogen atomic clock.Compared with the traditional rubidium atomic clock,Hg+clock has great application prospects.There are many similarities and differences between rubidium atomic clock and Hg+atomic clock.The analysis of the differences between them can draw lessons from the existing rubidium clocks and deepen the understanding of the working process of Hg+clock.The principle and key technology of the two are compared and analyzed,which can be used for reference for the development of Hg+clock.
