一种改进的逐差法数据处理方法

A Kind of Improved Method of Iso Interval Data Processing

在物理实验或测量实践中，经常碰到一类通过自变量等间隔变化来获取测量数据的问题，基于简单算术平均法及通常的逐差法处理这类问题不能得到合理的结果，在充分利用原始测量数据的基础上，运用最小二乘原理推导出了合理的相关量的平均值计算公式。

There is a large number of measurement data in physics experiment and measurement,which is from iso interval independent varibales.Because the simple arithmetic mean method and the usual subtracting one by one method are irrational in processing these data,we make use of all original measurement data and deduce the rational formula for calculating related quantity's mean,based on the least square method.And finally,we also gain a simple result.
