摘要
刻划了多项式环Ｒ［ｘ］和Ｒ［ｘ，ｘ－１］的分次Ｊａｃｏｂｓｏｎ根，并引进分次局部环概念，证明了Ｒ是局部环当且仅当Ｒ［Ｘ］是分次局部环，当且仅当Ｒ［ｘ，ｘ－１］是分次局部环．
in this paper, characterizes the graded Jacobson radical of polynomial rings R[x] and R[x, x-1]and introduces concepts of graded local rings and proves that R is a local ring if and only if R[x] is a graded local ring, if and only if R[x, x-1]is a graded local ring.
