A microwave frequency standard based on laser-cooled 171 Yb + ions at Tsinghua University has been investigated. More than 10 5 171 Yb + ions were stably trapped for over 40 hours. The ground-state hyperfine splitting frequency of 171 Yb + was determined to be 12642812118.4672(8) Hz with a fractional frequency uncertainty of 6.33×10 −14 . Our work is in a continuous line with that of other scholars.
