摘要
Abstract
The long term stability of the superfluid transition temperature of helium has been studied in the past ten years using six cells sealed in 2000. The measurements are made in four laboratories with a regular procedure. A rhodiumiron resistance thermometer with series number of 229841 is used at forty-three measurements to realize the superfluid transition temperature of helium with the standard deviation of O. 035 mK.关键词
