摘要：
A one volt Josephson voltage standard which easily permits exchange of Josephson junction arrays (JJA's) has been constructed and installed at the Spanish TPA. Two different types of JJA's, Nb/NbO(x)/PbInAu from NIST and Nb/Al2O3/Nb from PTB, have been used to determine the evolution of Zener references, both being compatible with our system. No discrepancies within our uncertainty (18 parts in 10(9)) were observed when, for a given reference, the arrays were interchanged. Moreover, preliminary calibration results obtained at two other laboratories-in one of our references-show good agreement with our data.
