摘　　要：〔目的〕为确定成品油检验抽样方式提供依据。〔方法〕采用GB/T4756-1998规定的取样方法和GB/T1884-2000、GB/T1885-1998的测定方法对部分成品油的密度在大容器储油罐中的分布进行了分析和研究。〔结果〕在所试验的储油罐中,其油品分布情况为:汽油点样极差为0.0026g/cm3,点样最小差值为0.0010g/cm3,最大绝对误差为0.0013g/cm3,柴油点样极差为0.0010g/cm3,点样最小差值为0.0006g/cm3,最大绝对误差为0.0005g/cm3。〔结论〕经过调合混匀的油品储油罐中的油品密度可以认为是均匀状态分布,刚生产的汽油在储油罐中的油品密度则不是以均匀状态分布。This article intends to research on the density- distributing condition of certain refined oil in some greater capacity tanks (such as shore storage tanks etc.).By experiments we find the density- distributing condition of certain refined oil like that : for gasoline, the max difference between two single spot sample is 0.0026g/cm3 ,the minimal difference is0.0010 g/cm3 ,and the max absolute error is 0.0013 g/cm3;for diesel oil, the max difference between two single spot sample is 0.0013g/cm3 ,the minimal difference is0.0006 g/cm3 ,and the max absolute error is0.0005 g/cm3 .As for the most of refined oil ,their density-distributing conditions can be considered to be equal .but a few individual cases are of exception ,they can not be considered that the density distributing condition are equal.
