摘要
定义了Ｆｕｚｚｙ集合的点式差运算和对称差运算以及格论的差运算和对称差运算，讨论其基本性质，证明两种差运算都拥有ｄｅＭｏｒｇａｎ对偶律．
In this paper,the pointwise difference operation and symetric difference operation and the lattice-theoretical difference operation and symetric difference operation on fuzzy sets are defined,their basic properties are discussed,and the de Morgan dual laws on the two kinds of difference operations are established.
