析取项 meaning in Chinese

disjunct

On one hand , we improve on one of the existed algorithms which named attribute reduction algorithm based on discernility matrix and logic operation . we propose a new transformation method from conjunction matrix to disjunction matrix that avoids the manual work or global search and can save the time and space . on the other hand , most traditional methods didn ’ t integrate with database operations
主要做了两方面的工作,一方面,对已有的基于可辨识矩阵和逻辑运算的属性约简算法进行了改进,提出了一种从合取项矩阵到析取项矩阵直接转化的方法,避免了传统的人工转化或全局搜索的方法,节省了空间和时间。
