摘　　要：本文通过分析同一样本绒毛分离前的原绒及与净绒纤维平均细度的相关性,得出了不同年龄公母羊净绒纤维平均细度估测公式。其中,适用于1岁龄公羊的估测公式为y=15.9963-1.9399x+0.1799x^2-0.0037x^3,适用于2岁龄公羊的估测公式为y=12.1845-0.4397x+0.0416x^2,适用于1岁龄母羊的估测公式为y=e(3.6085-13.568/x),适用于2岁龄母羊的估测公式为y=17.2368-1.0026x+0.0576x^2,适用于3岁龄及以上母羊的估测公式为y=0.9587+1.1476x-0.0126x^2。y代表净绒纤维平均细度值,x代表原绒纤维平均细度值。上述公式的准确性分别为91.8%、76.3%、62.3%、76.8%和46.9%。Based on the correlation between the average fineness of the cashmere and the cashmere fiber before the separation of the villus.The estimation formula of the average fineness of the cashmere of different age buck and doe is obtained.The regression equation for 1-year-old buck was y=15.9963-1.9399x+0.1799x2-0.0037x3,and the regression equation for 2-year-old buck was y=12.1845-0.4397x+0.0416x2,y=12.1845-0.4397x+0.0416x2,and the regression equation for 1-year-old doe was y=e(3.6085-13.568/x),and the regression equation for 2-year-old doe was y=17.2368-1.0026x+0.0576x2,and the regression equation for 3-year-old doe was y=0.9587+1.1476x-0.0126x2,y means the average fineness value of cashmere fiber,x means the cashmere fineness before separation.Accuracy percent for regression equations reached to 91.8%,76.3%,62.3%,76.8%and 46.9%respectively.
