| Abstract: | A brief history of atomic clock for time keeping and its development introduced. At present, the frequency uncertainty of 10-18 can be reached by optical clock. Optical clock is now recognized that the most likely for the new time and frequency standard in the future. National Time Service Center responsible for the overall national Atomic Time to build and maintain in China, is the establishment of the International Atomic Time TAI major participating units. We give a introduction of the Strontium optical ... |
