浅谈容量计重中常用的密度温度系数和体积温度系数

A Discussion on Density Temperature Factor and Volume Temperature Factor Used in Volumetric Survey

本文以纯水为例,介绍了确定液态物质密度温度系数和体积温度系数的一种方法,并分析了该方法产生的误差。用这一方法确定的精炼棕榈油的密度温度系数更加合理。

In this paper,a method is illustrated by the example of water for the determination of the density temperature factor and volume temperature factor of the liquid substances,and the error incurred is analyzed.The study shows that the density temperature factor of RBD palm oil determined by this method will be more reasonable.
