A recent determination for the SI values of the gyromagnetic ratio of proton Yp' and the Josephson frequency-voltage quotient 2e/h were completed at NIM in June, 1994. The results are:Yp' (abs) = 2. 6751535(23)×108T(-1)s(-1) and 2e/h = 483597. 89(43) GHz/V with the uncertainties of 0. 86ppm and 0. 88ppmrespectively. Meanwhile, the improvements of the measurement apparatus are described in this paper.
【Key Words】: Gyromagnetic ratio of proton Absolute measurement Josephson constant
