Classification on Full Symmetric Function Sets and Decision on the Minimal Covering Members in Partial Four-valued Logic
部分四值逻辑中完满对称函数集的分类及最小覆盖成员的判定

According to the completeness theory and concept of similar relationship in partial k-valued logic,the full symmetric function sets were classified by means of similarity relationship and some sets were proved minimal covering component of precomplete classes.
