摘要
通过分析与比较,获得了能准确反映体重与体长、胸围关系的回归公式:雌鲟y=1.832×10^(-4)(x_1x_2)^(1.337)(n=29,γ=0.980,sd=12.095,C.V=5.28%);雄鲟y=2.490×10^(-5)(x_1x_2)^(1.527)(n=52,γ=0.965,Sd=5.601,C.V=6.40%)。
After carefully analysing and comparing, we obtained the regression formula which can accurately reflect the relationship between the fish body weight and the fish body length and chest measurement. To the female is:y = 1.832×10^(-4_ (x_1x_2)^(1.337) (n=29, r=0.980, sd=12.095, C. V=5.28%)and the male y=2.490×10^(-5_(x_1x_2)^(1.527)(n-52, r=0.965, sd=5.601, C. V=6.40%),
