摘要
Due to various reasons, the inspection methods often need to be changed, and the detection reagents often need to be replaced. In this study, a comparative experiment was conducted between the ethanol-based and ether-based determination methods for oil content in imported wool. The determination results obtained from the two methods were treated as abscissa and ordinate respectively,and their linear relationship was analyzed. According to the linear regression analysis, the conversion equation of determination result between the two methods was obtained. In addition, the repeatability admissible error and reproducibility admissible error were established through analyzing the comparative experimental results by scientific software. This study will bring new ideas for further researches in this field, and provide reference for solving the similar problems in actual inspection work.
在检测工作中,时常由于各种原因,需要更改检验方法或调整检测试剂,该文通过系统实验室间2种方法的对比试验数据,将两种方法结果分为x、y轴,做相关线性趋势图,通过计算分析建立两种方法的互换方程式;并在标准未给定允许差的情况下,采用大量的检验对比数据,通过科学的计算软件,建立重复性、再现性允许差,为该领域进一步的探索与科学研究拓展思路,以及今后在实际检验工作中解决类似问题提供参考。
