At present,the colorimetric method for detecting the concentration of material is based on the relation between the color reading and the quantity of material. In order to improve the accuracy of detection,based on multivariate linear models of color reading and material concentration,a generalized linear model of color reading and substance concentration is established by using Logistic transformation. Further,the effect of the amount of data and color dimension on the model is discussed,and it has practical significance.%目前常用的检测物质浓度的比色法,基于颜色读数和物质浓度的数量关系.为了提高检测的精准度,在颜色读数和物质浓度的多元线性模型的基础上,利用Logistic变换建立颜色读数和物质浓度的广义线性模型.进一步探讨了数据量和颜色维度对模型的影响,具有实际的应用意义.
