【摘要】：吴占鹏．秩协方差分析及应用．数理统计与管理，，１９９８，１７（３），７～１０．在随机区组试验中，区组内往往存在土壤梯度差异，使试验误差增大。为此，本文提出秩协方差分析方法，即把土壤差异εｉｊ分解成Δ·ｘｉｊ和δｉｊ两个成份，从中剔除土壤梯度差异Δ·ｘｉｊ对试验精度的影响，以提高试验结果的可靠性

In order to improve the reliability of the test results, a rank covariance analysis method is proposed in this paper, that is, the soil difference 蔚 ij is decomposed into 螖 xij and 未 ij components, and the influence of the soil gradient difference 螖 xij on the test accuracy is eliminated.
