摘要： 在左(或右)~McCoy~环上的矩阵环和上三角矩阵环中,
找到了一些左(或右)~McCoy~子环;
同时给出了没有单位元的左(或右)~McCoy~环.
说明了一个左~McCoy~环不一定是右~McCoy~环,
一个右~McCoy~环不一定是左~McCoy~环.
最后指出~reversible~环满足一个~McCoy~条件.

关键词: 右~McCoy~环, 左McCoy~环, McCoy~环, 矩阵环, 上三角矩阵环

Abstract: Some right (resp., left) McCoy  subrings of matrix ring
and upper triangular matrix ring over a right (resp., left) McCoy
ring are presented. At the same time, we also give that  a right
McCoy ring is not left McCoy and  a left   McCoy ring is not right
McCoy. Consequently, reversible  rings satisfy a McCoy condition.

Key words: right McCoy ring, left McCoy ring, McCoy ring, matrix ring, upper triangular matrix ring
