摘要
本文根据最小二乘原理提出裂区设计二因素试验结果的二次回归分析法，包括建 立试验指标与试验因素间的二元二次回归方程和显著性检验。此法开辟了分析裂 区试验结果的新途径，能从试验结果中提取新的重要信息，从而提高了试验结果 的利用率，最后举例说明．
Based on the principle. of least squares, this paper deals with the application of the quadratic regression analysis method to the. analysis of the data of split-plot desing with two experimental factors. The quadratic regress ion eguation of the experimental targetwith two factors and the test of significance are given. This approach indicates a new way to analyze the results of factor experiment. Owing to gain more useful information. this approach is by far more efficient in comparison with the analysis of an ordinary split-plot design. A numerical illustration is also given.
