主成分回归在PU弹性体物理性能测量中的应用

The Application of Principal Component Regression on Mechanical Property's Measure of Polyurethane Elastomer

物理性能参数间存在着相互关系,该文将以撕裂强度为例对其进行探讨。采用了最小二乘回归和主成分回归,对撕裂强度受其他物理性能的影响关系进行详细的分析,并给出两种方法的结果分析,来体现主成分回归的优越性。其他物理性能之间的关系可以用相同的方法得到。

There lie some correlations among mechanical properties. In this paper, we will take tear strength for example to discuss this correlation. We will apply least square regression models and principle component regression one to analyses in detail the relation, which tear strength is effected by others. And we give the result analysis of two methods to manifest the superiority of principle component regression. Any correlation between some mechanical property and others can find by same way.
