摘要
中国科学院上海天文台1958年开始原子频标的研究,先后研制成功氨分子钟和各种类型的氢原子钟,并实现主动型氢钟的商品化生产。迄今为止,已经研制生产主动型氢钟60多台,广泛用于科学技术各领域。该文简单介绍了上海天文台原子频标的发展、性能指标的改进和氢钟的应用概况,并对今后的发展前景进行了展望。
Shanghai Astronomical Observatory has developed atomic frequency standards since 1958. Ammonia maser and various kinds of hydrogen atomic clocks have been developed successfully. And the active hydrogen atomic clocks have been realized commercial productions. So for, more than 60 active hydrogen atomic clocks have been built in Shanghai Astronomical Observatory, and they have been used widely in the Scien-Tech fields. This paper introduces briefly SHAO＇s atomic frequency standards developments, the improvements of their performance specification and their applications. The developing future of atomic clocks in SHAO is also pointed out briefly.
