环加群的自同态环

ENDOMORPHISM RING OF ADDITIVE GROUP OF A RING

引入强零因子概念．证明无强零因子环可嵌入这个环的加群自同态环中．有单位元环是无强零因子的，但无强零因子环未必有单位元．由此，本文对已知的结果作了有实质性的推广．

Introduces the concept of strong zero divisor Proves that a ring withoutstong zero divisor can inserted into its endomorphism ring of additive group.And the ringwith identical element is a ring without strong zero divisor,but the later may not be theformer.Therefore the paper essencially extends the previous result.
