摘要：比色法是目前常用的一种检测物质浓度的方法。每个人对颜色的敏感差异和观测误差，使得这一方法在精度上受到很大影响。文章以组胺、溴酸钾、工业碱、硫酸铝钾、奶中尿素五种物质为研究对象建立了颜色读数和物质浓度的数量关系模型，并从模型的统计检验精度和误差分析两个方面择优选择辨识模型。#br#
Abstract: Colorimetric method is a commonly used method to detect the concentration of material. Because of the sensitivity#br# difference and observational errors of each person, the accuracy of this method is greatly affected. This paper established the#br# relationship between the number of models of color readings and the concentration of a substance with five kinds of materialhistamine,potassium bromated, potassium aluminum sulfate, industrial base, urea in milk-as the research object, and selected statistical model from the two aspects of test precision and error analysis.
