UNCERTAINTY ANALYSIS AND EVALUATION OF MAGNETIC SYSTEM OF ENERGY BALANCE SUBSTITUTING FOR MASS STANDARD

摘要：

This paper analyses the sources of uncertainty and evaluates the magnetic density in geometrical center of magnetic system, based on special structure of coil system of energy balance. It proved that the uncertainty u(I) of current existing in the coil of magnetic system would affect combined uncertainty of magnetic field uc(H0) to the greatest extent Therefore the high-precision constant-current source was recommended to diminish uncertainty of magnetic field of Energy Balance.
