释义	de Morgan’s laws Computer The two laws of a Boolean algebra that provide a method of expressing the complement of a complex expression in terms of the complements of individual components: $\begin{array}{l} (x \lor y)' = x' \land y' \\ (x \land y)' = x' \lor y' \end{array}$ The pair is self-dual.
