In this paper, the definition of nil radical of zero normal NCD-ring R is given, and the proof is made for that nil radical n(R) is the greatest ideal of R and R / n(R)has no non-zero nil ideals when n(R) is the smallest ideal of R.
本文给出零正规ＮＣＤ－环Ｒ的诣零根ｎ（Ｒ）的定义，完成了“零正规ＮＣＤ－环Ｒ的诣零根ｎ（Ｒ）是Ｒ的最大理想及ｎ（Ｒ）是使商环Ｒ／ｎ（Ｒ）无非零诣零理想的最小理想”的证明。
Furthermore, balloons in assemblies drawing could not be rearranged.
在工程图的个性化处理方面有很多不足,比如一些特殊符号如液压气动符号、电气符号等无法直接添加,此外,装配体工程图中的零件序号也无法重排。
