| 摘 要： | 提出了用具有超椭圆信息量损失准则的主成分分析双向变量选择法（ＥＰＴＳＶ法）来确定最佳变量子集。赋予超椭圆准则相应的几何解释，具有多维空间的直观性。利用此ＥＰＴＳＶ方法对一实际合成氨系统５０多个变量进行了选择，得到了７个主变量，即最佳变量子集。

| Abstract: | In this paper we present a revised principal components two-way selection variables (EPTSV)algorithm with super-ellipse information loss standand (J)to obtain the optimal variable subset. The geometrical explanation of standard J is proposed. By the EPTSV method,seven main variables of the synthetic ammonia system is selected from more than fifty variables and the optimal variable subset is obtained. |
