对 45只Beagle犬的体重与各脏器重量之间的关系进行了回归分析 ,并计算出相应的直线回归方程。对Beagle犬的脏器系数进行分析 ,显示脾脏、胸腺的变异系数较大 ,提示根据动物的脾脏、胸腺重量来评价其免疫功能时 ,要慎重考虑 The relationship between the weight of 45 Beagle dogs and the weight of each organ was analyzed by regression analysis, and the corresponding linear regression equation was calculated. Analysis of organ coefficients in Beagle dogs showed that the coefficients of variation of the spleen and thymus were large, suggesting that careful consideration should be given to assessing the immune function of animals based on their spleen and thymus weights
