国际计量委员会(CIPM)下设的时间频率咨询委员会(CCTF),于2006年9月14-15日在巴黎召开第17次会议。会议鉴于:(1)近年来,飞秒激光光学频率梳实现了微波-光学频率的直接准确测量;(2)几种候选辐射标准频率的不确定度持续减小。经讨论研究相应具体实施对策,通过下述建议方案,并提请
The Time Frequency Advisory Committee (CCTF) under the International Committee on Measurement (CIPM) held its 17th meeting in Paris on September 14-15, 2006. In view of the meeting: (1) In recent years, the femtosecond laser optical frequency comb has achieved direct and accurate measurement of the microwave-optical frequency; (2) the uncertainty of several candidate radiation standard frequencies has continued to decrease. After discussing the specific implementation measures, adopt the following proposals and submit them
