测量
土壤释放效应已经通过每种污渍的Delta E(ΔE)测量。
Delta E定义为未洗涤的污渍与已洗涤的污渍之间的色差(在L*a*b*色空间内)。
在洗涤之前及之后，通过使用Epson扫描软件的Epson Perfection 4490Photo扫描仪，在以下设置下测量每种污渍：
■专业模式.
■文件类型：反射
■文件来源：文件表格
■自动曝光类型：光照
■图像类型：48位色彩
■扫描品质：最佳
■分辨率：400dpi
■无色彩校正
■防UV 400nm
接着，使用软件Image J 1.4.3.67版(获自因特网的自由软件)，使用提供L*a*b*色空间内的色彩信息的宏指令，分析每种污渍的色彩。
结果(基于第1循环，40℃)
Delta E定义为未洗涤的污渍与已洗涤的污渍之间的色差(在L*a*b*色空间内)。
