Finally, the equivalence properties between Boolean matrix representation and algebra representation of attribute reduction are proved.

最后证明了属性约简在布尔矩阵和代数两种不同表示下是等价的。

Bitwise operators perform Boolean algebra on the corresponding bits in the two arguments to produce the result.

按位运算符会对两个自变量中对应的位执行布尔代数，并最终生成一个结果。
