In 1997, Lenhard Ng Michelle Schultz[1] gave the definition of k -ordered Hamilton graphs,namely, let G be a Hamiltonian graph of order n,and for a positive integer k with k ≤n, we say that G is k -ordered if for every sequence S : v1 , v2,Λ,vk of k distinct vertices, there exists a hamiltonian cycle C of G such that the vertices of S are encountered on C in the specified order.

年， Lenhard Ng Michelle Schultz[1]给出k-可序( k ？ordered)哈密尔顿图的定义，即设G是n阶哈密尔顿图，对于正整数k，称G 是k -可序图，如果对于任意给定的k 个互不相同的顶点的有序子集S =( v1 ，v2，Λvk)( 2≤k ≤n)，存在G中的哈密尔顿圈C 包含S 且不改变其中元素的顺序。2000 年，R.J。

Methods: Twenty-four rabbits were randomly divided into three groups:① the control group(group C, n=8): received sternotomy only and no ischemia;② the ischemia/reperfusion group(group I/R, n=8): the left lungs of rabbits were rendered ischemia by ligating the left pulmonary hili for 60 minutes followed by 60 minutes reperfusion;③ the edaravone group(group E, n=8): the left lungs were rendered ischemia for 60 minutes followed by 60 minutes reperfusion, and 10 mg/kg edaravone was administered intravenously 5 minutes prior to ischemia. Blood MDA and SOD were measured. Protein concentrations, WBC count, and PMN percentage in broncho-alveolar lavage fluid were determined.
