    证明:若无向图[tex=0.786x1.0]LyvDGollVJ+xwurtsLcn0g==[/tex]恰有两个节点[tex=0.643x0.786]dFKQavWFzybe6S1GPVXNhQ==[/tex]和[tex=0.5x0.786]pmD1JbahT9zMRAbBNi045A==[/tex]度数为奇数,则在[tex=0.786x1.0]LyvDGollVJ+xwurtsLcn0g==[/tex]中[tex=0.643x0.786]dFKQavWFzybe6S1GPVXNhQ==[/tex]可达[tex=0.5x0.786]pmD1JbahT9zMRAbBNi045A==[/tex]。如果[tex=0.786x1.0]LyvDGollVJ+xwurtsLcn0g==[/tex]是有向图,上述结论是否成立?
