摘要 研究了当p≥q≥s+1≥10时,K-s(p,q)中图的3分划数的计算公式和3分划数一些下界及其极图,并得到了许多新的色惟一二部图. In this paper, we shall investigate the calculating formula of 3-independent partition numbers of kiportite graphs G and give some graphs with low bounds of 3-independent partition numbers of G when G∈ K^(-s)(p,q) , where p≥q≥s+1≥10. We also obtain many new chromatically unique bipartite grpahs.
