均匀性是标准物质最基本的属性。该文通过对标准操作油样品在20℃时密度和100℃运动粘度进行均匀性研究,20℃时操作油密度的统计F值为1.84,100℃时运动粘度的统计F值为2.06,均小于临界值Fα2.31(α为0.05)。结果表明研制的操作油均匀性良好。

Homogeneity is the most basic standard material properties. We studied on density at 20℃ and kine-matic viscosity at 100℃ of sample,statistics value F of operating oil density at 20℃ was 1. 84,the kinematic viscos-ity was 2. 06 at 100℃,all were less than the critical value Fα2. 31 (α=0. 05). Results showed that the operation oil uniformity was good.
