摘要
应用Ｌｏｇｉｓｔｉｃ模型拟合彩色感光材料的Ｄ－ｔ曲线，是一种定量分析Ｙ，Ｍ，Ｃ分解密度与曝光时间关系的新方法。结果表明，Ｙ，Ｍ，Ｃ分解密度的预测值与实测值达到了较好的吻合。决定系数ＲＹ２＝０．９８２５，ＲＭ２＝０．９６７５，ＲＣ２＝０．９９４３，相应的标准偏差σＤＹ＝０．０５３，σＤＭ＝０．１００，σＤＣ＝０．０１５，可以满足定量计算的精度要求。
A novel method by using Logistic model to fit D - t curves of the color photosensitive materials is proposed to analyse the relations among Y, M, C analytical density and the exposure time. The results shows that the predicted value of Y, M, C analytical density fits the measured value fairly good. The decision coefficients are RY2 = 0.9825, RM = 0. 9675 and RC2 = 0. 9943. The corresponding standard deviation areσ DY = 0. 053, σDM = 0. 100 and σDC = 0. 015. Those results are able to satisfy the precision demand of the quantitative calculation.
