正交递归方法用于研究钢中微量元素对钢的力学性能的影响

Multi variable Analysis Method Used for Studying Influence of Trace Elements in Steel on its Mechanical Properties

通过对含有８种微量元素和５种热轧工艺条件的ＣｕＰＣｒＮｉ钢的数据，应用化学计量学方法（包括变量筛选及ＰＬＳ回归等方法）进行处理，选出对钢性能影响较为显著的几种变量。

The data of CuPCrNi Steel includes 8 trace elements and 5 heat treatment parameters. Through the application of Chemometrics methods(including the variable dimension expansion and the variable selection method, PLS regression method and so on) , several primary variables, which influence the properties of the steel ,can be selected.Thus accurate prediction models to predict the properties of the steel can be built.
