【摘要】 颜色是衡量棉花质量的重要参数之一。长期以来,我国的棉花色度量值来源于美国农业部,没有自行复现、保存棉花色度量值的能力。中国计量科学研究院与中国纤维检验局合作研制的氙灯型棉花色度标准装置采用脉冲氙灯照明样品,CCD探测器分光谱接收的方法,测量可见波段光谱反射比并计算得到棉花校正色板的反射率R_d和黄度+b,量值溯源至色度国家基准。解决了我国自行保存、复现棉花色度量值的问题。更多还原

【Abstract】 Cotton color is one of the key parameters for evaluation of cotton quality. China do not have the capability to realize and maintain the scale of cotton color and the scale used to trace to USDA. National Institute of Metrology and China Fiber Inspection Bureau developed a standard apparatus for cotton color,in which sample illuminated by xenon lamp,reflection signal detected by CCD detector,spectral reflectance of sample is measured and the reflectance R_d and yellowness +b can be calculated.更多还原
