摘要
标准玻璃浮子是用于密度梯度管中,标定管中液体密度大小的特制玻璃小球。本文依据JJF 1709—2018《标准玻璃浮子校准规范》,介绍了标准密度浮子的测量方法和测量结果不确定度的评定。
Standard glass floats are used in density gradient columns to determining the density of the liquid columns. This paper analyzes the evaluation of uncertainty of testing standard glass floats according to JJF 1709—2018 Calibration Specification for Standard Glass Floats.
