摘　　要：通过双球管重量法测定珍珠岩样品中化合水含量的不确定度进行分析评定,找出影响不确定度的因素,为实验室的质量控制和用双球管重量法测定其它样品化合水含量的不确定度评定提供参考。Uncertainty evaluation of measurement results for the determination of combined water in perlite samples by double tube gravimetry was carried out in this article in order to find the influence factors of uncertainty. The aim was to provide reference for the quality control in laboratory and uncertainty evaluation of measurement results for the determination of combined water in other samples by double tube gravimetry.
