摘　　要：分析了主元分析方法的基本概念与原理,从数学的角度讨论了主元分析的具体实现。将主元分析应用于伊斯曼流程中,详细地讨论了如何确定主元及分析得出主要故障及故障时间,通过V isual C++来实现基于主元分析的故障诊断。最后,对于界面开发的设计思想作了具体的介绍,同时也对界面制作做了具体的讨论。Analyzed component analysis. the basic concepts principles and mathematical methods of the methods of principal Among them, the concrete realization of principal component analysis was discussed on the view of mathematical point. At the same time, discussed in detail how to apply the PCA, how to determine the principal component and how to get the main fault and main time in Tenness Eastman process. Also discussed how to realize fault diagnosis based on principal component analysis. In the end, the methods of the design of interface development have done a specific briefing, and the ways to product the interface were discussed.
