The mass benchmark is the only real benchmark among all fundamental physical SI units, and the drawback is that it's easy to be affected by the environment, resulting in the change of the mass value. In this paper, recent research progresses at home and abroad on the surface status predication are summarized and the prediction research method on the surface status prediction of weights in institutes home and abroad is presented, including the influence analysis on the mass standards during transferring from vacuum to air and establishment the mass observation model and absorption correction model,etc. Through the research on the surface status of weights and absorption correction technology, the mass measurement accuracy can be ultimately enhanced, which lays a technical foundation for the upcoming redefinition of mass units' research. |
