花岗岩残积土游离氧化铁含量和含水率对其颜色的影响研究
Research on the effects of free iron oxide and moisture content of granite residual soil on its color characteristics
摘要
Abstract
To reveal the intrinsic connection between the color information of granite residual soil and its physi-cal and chemical characteristics,a coupling model between the color information of granite residual soil(R,G,B component characteristic value)and the content of free iron oxide and moisture content was constructed through multiple regression analysis.The results show that with the increase of free iron oxide content,the char-acteristic value of R component increases significantly,indicating a clear positive correlation between them;while the increase of moisture content decreases the characteristic value of R,G and B,showing significant neg-ative correlation.The stable coupling relationship between RGB color information and free iron oxide content and moisture content indicates that the color information of granite residual soil can effectively reflect the varia-tion law of free iron oxide content and moisture content.关键词
