论文摘要
令$ g $为简单的立方2个连接的平面图。对于每一个$ 2 $ -FACTOR $ x $ $ g $带有$ n $ -components存在一个简单的汉密尔顿平面图$ j \ subset g^{2} $，因此$ | e（j）| = | e（g）| + 2n -2 $和$δ（J）\ leqslant 5 $。
Let $G$ be a simple cubic 2-connected plane graph. For every $2$-factor $X$ of $G$ having $n$-components there exists a simple hamiltonian plane graph $J \subset G^{2}$ such that $|E(J)|= |E(G)| + 2n -2$ and $Δ(J) \leqslant 5$.
