回顾了经典诊断方法和稳健诊断方法的基本原理，讨论了奇异点诊断中的掩蔽与淹没现象，再定义主灵敏度矢量，可知其中的极值点就是可能的奇异点。

Based on the basic theories of traditional diagnosis methods and robust diagnosis methods, masking effects and swamping effects in outliers diagnosing process were discussed in some detail.

为了计算项目集的支持度，提出了数据库特征矩阵和特征矢量的概念。

To calculate the support of an item-set the authors define characteristic matrix and characteristic vector of debase.
