前言在定量分析实验中往往会产生这样的问题,即分析测定结果是否准确以及究竟准确到什么程度。我们知道尽管分析方法很准确,仪器很精密,试剂很纯净,从事实验者很富有经验……,都不可能获得与被测物所含某物质量绝对相等的结果,而且多次重复不可能总是得到相同的测定数值。可见定量分析实验中的误差是客观存在的,不可避免的。当然随着分析方法的不断革新和操作技术水平的不断提高,可以越来越使得这种“误
Preface The problem often arises in quantitative analysis experiments is to analyze the accuracy of the measurement results and to what extent. We know that even though the method of analysis is accurate, the instrument is very precise, the reagents are pure, and the experimenter is very experienced ... it is impossible to obtain the exact equivalent of what is contained in the analyte, and it is impossible to repeat Is to get the same measurement value. Visible quantitative analysis of the error in the experiment is an objective reality, inevitable. Of course, with the continuous reform of analytical methods and continuous improvement of operational skills, this kind of "mistake
