设G是一个图,若去掉G中的任意n′个顶点的剩余子图仍是分数（g,f,m）-消去图,则称G是一个分数（g,f,n′,m）-临界消去图.本文给出了图G是分数（g,f,n′,m）-临界消去图的邻集条件,从而推广了以前文献中关于分数（g,f,n′）-临界图邻集条件的结论.
設G是一箇圖,若去掉G中的任意n′箇頂點的剩餘子圖仍是分數（g,f,m）-消去圖,則稱G是一箇分數（g,f,n′,m）-臨界消去圖.本文給齣瞭圖G是分數（g,f,n′,m）-臨界消去圖的鄰集條件,從而推廣瞭以前文獻中關于分數（g,f,n′）-臨界圖鄰集條件的結論.

A graph G is called a fractional （ g, f ,n＇ ,m ）-critical deleted graph, if any n＇ vertices is re moved from G , then the remaining graph is a fractional （ g,f,m ）-deleted graph. In this paper,neigh borhood condition for fractional （ g, f, n＇,m）-critical deleted graphs was given, thus the neighbor hood condition of （ g,f,n＇ ）-critical graphs which was raised in previous paper was extended.
