基本解釋[數(shù)學]路可擴詞組短語短語path extendable graph 路可擴圖extendable path 擴路path extendable更多詞組專業(yè)釋義數(shù)學路可擴In the fourth chapter,we mainly study paths of all graphs about degree conditions and give the following results:Theorem4.3 Let G be a graph of order n≥3. If d（u）+d（v）≥n+1 for every pair u,v,then G is path extendable.在第四章中,討論了圖中在與度有關的條件下關於路的幾個結果:定理4.3設G的堦n≥3,如果G中任意一對不同的頂點u,ν滿足d（u）+d（ν）≥n+1,則G是路可擴的。
