摘　　要：引入了图的符号星k限定控制的概念,从而求出了星图和轮图的符号星k控制数.还刻画了满足γ′_(ss)(G)=1/2(2r+s)的图,基中γ′_(ss)(G)表示图G的符号星控制数.最后对图的符号星部分控制的已有结果作了改进.In this paper we introduce the concept of signed star part limiting k-subdomination in graphs, thus find the signed star k-subdomination numbers of star and wheel graphs and characterize the graphs with γss=1/2（2r＋s）at last we improve the previous results of thesigned star part domination numbers.

关 键 词：符号星部分控制数 符号星控制数 符号星k控制数
