根据上下确界的性质,首先利用一个满足交换律和结合律的二元函数得到了几个构造三角模和三角余模的方法;然后又利用一个只满足结合律的二元函数得到了几个构造三角模和三角余模的方法。
Based on the properties of supermum and infimum, some construction methods for t-norm and s-norm are given by using a binary commutative and associative function.Furthermore, other constructive methods for t-norm and s-norm are given by using a binary associative function.
