摘要
针对羊绒鉴别问题,研究光学显微镜下纤维鳞片纹图基因码的统计规律。结果表明:羊绒鳞片纹图基因码中除纤维直径的均匀性较好、变异系数较小外,其他基因码的变异系数均较大;所有纹图基因码中除了鳞片矩形度的最优拟合为正态分布外,其他形状参数的最优拟合均为对数正态分布,其拟合相关度均超过了0.99;羊绒纹图基因码中相对形状参数离散度较小而绝对形状参数离散度较大;在所有的纹图基因码中,鳞片矩形度的离散度最小而面积的离散度最大,羊绒纤维鳞片形状更似方形或窄矩形。
For the identification of cashmere, the statistical regularities of scale pattern genetic code under optical microscope are studied. These results show that fiber diameter is even and its coefficient of variation is smaller than that of other scale pattern gene codes. Among all scale pattern gene codes, the optimal fitting of scale rectangle factor follows normal distribution and that of all other shape parameters follow lognormal distribution with a correlation higher than 0.99. Further comparisons show that among all scale pattern gene codes, the dispersion of relative shape parameters is smaller than that of absolute shape parameters. The dispersion in scale rectangle factor is smallest and largest in scale area. Scale looks more like a square or narrow rectangle.
