原子时频技术进展

Recent Progress in Atomic Time and Frequency

概述了传统原子频标的现状,以及新型原子频标和国际原子时的研究进展。介绍了为适应高精度新型频标和国际原子时的比对需要而开展的远程时频传递技术。

The status of traditional atomic frequency standards and research progress of new atomic frequency standards, as well as new horizontal of international atomic time （TAI） are described. Recent research and progress of long- distance time and frequency trandards comparison and atomic time comparison with high precision are also introduced.
