| 摘 要： | “误差和数据处理”是分析化学数材中的重要部分,近年来教材中内容变化较大。本文就这方面的内容、重点和关键问题作了讨论。误差是测定值与真实值之差,表示测定的准确度;偏差是测定值与平均值之差,表示测定的精密度,二者既有联系又有差别。按高斯误差分布方程作图可得偶然误差的正态分布曲线,根据方程和曲线可得偶然误差的分布规律,可求出偶然误差出现的概率,从概率可得到平均值的置信区间。

| Abstract: | "Error and data Processing" is an importance part of analytical chemistry. The difference between measured value and true value is called error that shows measuring accurcy. The difference between measured value and mean value is called deviation that shws measuring precision. Accordng to Gaussian distribution equation, we can paint a curve and obtain the normal distribution curve of random error and the rule of random error. According to the rule, we may get probability of random and confidence interval. |
