摘　　要：回归方程是比色分析法数据处理的重要环节。在我国现行水质监测分析方法中,对于回归方程中各参数的有效数字,未做明确规定。本文结合在分析数据处理过程中,遇到的实际问题及产生的影响,提出不同分析方法及仪器灵敏度确定有效数字的保留位数,以此提高分析结果的准确度和可比性。Summary Tropical Equation is an Important link of data processing of colorimetric analysis method. In the current water quality monitoring analysis method of our country, different kinds of parametric efficent figure in tropical equption aren't clearly provided. According to practical problems and effects met in the cause of analysing data processing We suggest that concerned department determine efficient figures reserved place on the basis of different analysis method and apparatus sensitivity So as To improve degree of accuracy and contrast possibiliry of analysis result.
