摘　　要：本文研究了广义幂级数环与其系数环在本质理想和非奇异性上的关系.利用本质理想的定义和性质,得到了广义幂级数环的左理想为本质左理想的若干充分必要条件.在此基础上,给出了广义幂级数环为左非奇异环的充分必要条件.In this article, we study the relations between generalized power series rings and their coefficient rings on essential ideal and nonsingularity. By using the definition and properties of essential ideal of rings, we show some necessary and sufficient conditions for a left ideal to be a left essential ideal, and provide several necessary and sufficient conditions for generalized power series rings to be a left nonsingular ring.
