组合工艺中的正交试验设计与二次正交回归分析

在化工、治金、选矿等工业生产和科学试验中，存在许多组合工艺问题，即产品的性能指标与生产工艺中许多因素有关，如何选取工艺中的各因素的值，以便在成本最小的情况下，获得所在地要求的产品性能；或是使产品的其它性能指标达到要求而主要性能最优，这些都是组合生产中最优组合问题和最优问题的求解。目前，主要采用正交试验法和回归分析法，作介绍了正交试验法的试验设计和试验安排、直观分析和方差分析。

The Orthogonal experimental design in assessment method and quadratic Orthogonal regressive analysis

In the productions and experimentations of Chemical, Metallurgy, Mining, there are many Assessment methods problems, such as the guide line and line and performance correlate to many factors of the production and method, how to select the value of the factor of the method, so that we can achieve the performance of the products according to the local needs and cost the least, or the performance can achieve the target and the main performance reach the best all these are the resolution of optimization problems and the optimization problems in assessment produce. Presently, we mainly use Orthogonal experiment method and Orthogonal regressive analysis method, this thesis method, this thesis introduces the design and arrangement intuitionistic analysis of the experiment of the experiment of Orthogonal experimental method.
