摘　　要：为了减少回归预测值y的方差强烈依赖试验点在空间中的位置,降低误差的干扰,文中结合实例,采用回归旋转正交设计建立二次回归模型。通过统计检验,肯定了模型的可靠性和应用的有效性。同时文中给出了相应的SAS程序。In order to decrease the variance of the regression predictable value intensively depends on the station of experiment points in the space, and reduce the disturb of the error, this paper mainly introduces the application of the rotating orthogonal regression design to establish the regression model by combining the experiment. Through the statistic test, the regression model is reliable and valid. The corresponding SAS program is presented in this paper.
