摘　　要：本文对比了玻璃浮式密度计和U形振动管两种方法测定原油、残渣燃料油、航空煤油、涡轮机油、柴油的密度,除柴油外,其他油种采用U形振动管检测方法的使用比例在逐年上升,整体上,两种方法结果差值满足GB/T 1884—2000再现性要求,U形振动管检测精密度约一半较为明显优于玻璃浮式密度计。It is discussed two sets results of density of crude oils,residue fuels,jet fuels,turbine lubricants and diesels by glass float densitometer and U-shaped oscillating tube.In addition to diesel oil,the proportion of other oils detected by U-shaped vibrating tube is increasing year by year.As a whole,the difference between two methods'results is applicable to reproducibility limit of GB/T 1884—2000,and half of results precisions of U-shaped oscillating tube are better than that of glass float densitometer.
