Two important examples are constructed to show that an irredundant form probably is not a minimal form, and two definitions of essential fuzzy prime implicant are not equivalent.
结果表明，非冗余形式可能不是极小形式，关于本质模糊素蕴涵的两个定义是不等价的。
In minimizing a boolean function using the extraction method, the traditional steps are: getting the prime cover Z first; and then extracting the essential prime implicant from Z.
用精选法求布尔函数的最小化解时，传统的作法是先求出质覆盖Z，然后从Z中挑选必要质蕴涵项。
