证明了等价关系族构成的有界格，建立了函数复合的最大公因式、最小公倍式等概念，并对其存在唯一性作出证明。

This paper establishes the concept of maximal common factor and minimal common multiple for compound function and proves their unique existence.

将有界分配格上可逆矩阵的有关结果推广到坡上的矩阵。

Some results related to invertible matrices over bounded distributive lattice are generalized to matrices over incline.
