植物油密度是计算植物油质量的重要参数，运用数理统计方法，研究了进口精炼棕榈液油装货港计量密度与实验室计量密度差异对植物油计重的影响。结果表明：一些进口精炼棕榈液油装货港计量密度与实验室计量密度存在显著差异，在相同温度下其装货港计量密度比实验室计量密度高出0．3%以上，导致实到货物质量比船方计量质量短缺0．3%以上。针对密度虚高引起的进口植物油短重现象，提出了改进措施与建议。

Density of vegetable oil is an important parameter to calculate its mass. The effect of differ-ences between density provided by the loading port and density tested in the laboratory of imported refined palm olein on weighing was studied by the method of mathematical statistics. The results showed that there were significant differences between the density provided by the loading port and density tested in the laboratory of some imported refined palm olein, and the density of the loading port was higher by 0. 3%than that tested in the laboratory at the same temperature, which resulted in the actual mass short-age over 0 . 3%. The improvement measures and suggestions were put forward aming at the mass shortage of imported vegetable oil caused by artificially high density.
