分析化学各个分支要求运用数理统计方法表征数据结果时,都需用实验误差的术语和符号。当前国内外有关分析化学教材、专著和学术刊物中引用的很不一致,使实验误差教学和记录数据较为混乱。为使教学、科研理论计算和实验数据表征便于简化、交流,从而减少麻烦并有利于标准化,逐步改变一些不合理的习惯,在实践中不断修正和统一
Analytical chemistry branches require the use of mathematical statistical methods to characterize data results, the need for experimental error terms and symbols. The current domestic and international analytical chemistry textbooks, monographs and academic journals cited in very inconsistent, experimental error teaching and recording data is more chaotic. In order to facilitate the teaching, scientific theoretical calculations and experimental data characterization to facilitate the simplification and exchange, thereby reducing the trouble and is conducive to standardization, and gradually change some unreasonable habits, in practice constantly revised and unified
