论文摘要
我们报告了国家时间服务中心（NTSC）的87SR光学晶格时钟（SR1）中5S2 1S0-5S5P 3P0过渡的绝对频率测量。仔细评估其系统的频移，总相对不确定性为5.1E10-17。测得的绝对频率为429 228 004 229 872.91（18）Hz，相对不确定性为4.13E10-16，参考了BIPM通过全球导航卫星系统（GNSS）链接BIPM在圆形T公告中发表的主要和次要频率标准的集合。
We report the absolute frequency measurement of the 5s2 1S0-5s5p 3P0 transition in 87Sr optical lattice clock (Sr1) at National Time Service Center (NTSC). Its systematic frequency shifts are evaluated carefully with a total relative uncertainty of 5.1E10-17. The measured absolute frequency is 429 228 004 229 872.91(18) Hz with a relative uncertainty of 4.13E10-16, with reference to the ensemble of primary and secondary frequency standards published in the Circular T bulletin by BIPM through a global navigation satellite system (GNSS) link.
