摘要：

按照概念分类和概念定义的一般原则，对化学分析课程中有关测量数据处理的概念进行了梳理，包括化学计量学基本任务、准确度、精密度、误差等，对现行教材中存在的内容编排、概念用语、概念的定义展开商榷，并提出相关建议，以期为《化学分析》教材建设及学术用语规范提供思路。

关键词: 误差, 准确度, 精密度, 概念分类, 操作性定义

Abstract:

According to the general principles of classification and definition of concepts the concepts in the course of chemical analysis addressing metrical data are sorted out, including the basic tasks of chemometrics, accuracy, precision and error. Discussions are carried out on the arrangement of contents, concept terminology and definition of some concepts in the currently popular textbooks, and relevant suggestions are put forward, in the hope of providing reference for refining the textbooks of《Chemical Analysis》and standardizing academic terminology.

Key words: Error, Accuracy, Precision, Concept classification, Operational definition
