摘　　要：In November 2018,during the 26th General Conference on Weights and Measures(CGPM)in Versailles,France,a land-mark resolution was adopted to redefine four base units of the International System of Units(SI)(https://www.bipm.org/en/committees/cg/cgpm/26-2018/resolution-1).The kilogram,mole,ampere,and kelvin were redefined in terms of fundamental physical constants:the Planck constant(h),the Avogadro constant(NA),the elementary charge(e),and the Boltzmann constant(k),respectively.As illustrated in Figure 1(a),the new SI framework defines all seven base units based on fundamental constants,marking a complete transition of metrology into the quantum era.This system has been in effect globally since May 20,2019,on World Metrology Day.
