摘　　要：本文选取了4批进口精炼棕榈仁油,测定了不同温度下的密度曲线,应用回归分析方法,确定了在30~60℃范围内,4批精炼棕榈仁油密度温度系数均为0.00070 t/(m^(3)·℃),与常规植物油密度温度系数0.00064 t/(m^(3)·℃)不同。该研究结果表明,不同植物油密度温度系数会存在差异,而且选取距实测温度越近的基准温度进行基准温度密度测定,其他相应温度密度推定越合理。The paper selected four batches of imported refined palm kernel oil and measured their density curves at different temperatures.Using regression analysis,it was determined that the density-temperature coefficient of the four batches of refined palm kernel oil was 0.00070 t/(m^(3)·℃)within the range of 30-60℃,different from the density-temperature coefficient of conventional vegetable oil,which was 0.00064 t/(m^(3)·℃).The results of this study indicate that there are differences in the density-temperature coefficient of different vegetable oils,and selecting a reference temperature closer to the measured temperature for the determination of the reference temperature density leads to a more reasonable estimation of the density at other corresponding temperatures.
