摘要
测定了在河南种植的50个小麦品种(系)不同拉伸时间内5项拉伸仪指标,借助于多元分析方法,建立了一组有关拉伸仪指标对面积的回归方程,探讨了面积受控因子的变化规律,认为主成分回归分析在损失少量信息的情况下,能够拟合更具有实践意义的回归方程。
Five indexes about rheological properties of dough at different time were determined for 50 wheat cultivars (lines) grown in Henan Province. By the methods of multiple regression analysis, a series of regression equations about rheological properties of dough (independent variables) to the area (dependent variables) were built, and the regularities of the indexes influencing the area studied. In such a situation of losing a little experimental information, the practical regression equation could be imitated with the analysis of main components.
