密度副基准的量值复现

摘要

介绍了静力称量法基本原理、测量装置及测量过程、参数控制。采用静力称量密度量值传递方法实现了从单晶硅球密度到副基准密度计组全部137只浮计的量值复现，并对不同密度段的基准浮计进行了测量不确定度评估。%The basic principIe,apparatus,prOcedure and parameters by the methOd Of hydrOstatic weighing was intrOduced. With the hydrOstatic weighing,the density dessiminatiOn frOm the sOIid density primary standard—siIicOn sphere tO the secOnd primary standard—a grOup Of 137 hydrOmeters has been reaIized. The measuring uncertainty in fuII range has been evaIuated in detaiI.
