对边

If the edges are ordered pairs of vertices then we get the notions of a directed graph and directed multigraph.

如果边都是顶点的有序对，则得到有向图和有向重图的概念。

She had no way to go to take care of them, one down to earth exploded - without an "oh" that the pursuit of love, or Sally really find Sally, but love in another prison. But even in the United States after the latino hard, the book still reveal about the future of beautiful dreams and hopes. Evan LangSha spezia, want to leave mango street have a house of my own, want to find yourself to the sweet chains, to help more people find happiness... When you read her teenage little secret, whether YiZheng suddenly, then said musingly:"ah, be like me so." When I read the book in the lamp under small delicate, it seems from books out an elf, just like my favorite fairy tale, Peter pan, never island fairy, gently leap from my mind, salvage one old yellow, almost forgotten memory. So I made an illusion, like a young restore that once. When saw lang and essien spezia on her sister in the streets of the old shoes mooning, I think before age eight steal wear dad suit in front of the mirror is to imagine yourself as CEO of companies, she added, Cathy cat and queen of Egypt circles the only large friends and Sally like white crane son as pure between the friendship. Timid her cry in dining-room ate rice sandwich inside, Side mirror where film actress lips red... I glanced limpid stream of the summer as a pebble, fingers touched by watching the lamp of barley bread baking ovens, warmth, the paper seems to have touched the memory, eager to grow, and find me for my friendship, love, though I meditate on the mirror of me...

当看到埃斯佩朗莎和妹妹穿着妈妈的旧高跟鞋在大街上乱逛；我想到以前8岁时偷穿爸爸的西装在镜子前一边想象自己是某家公司的CEO，她和猫皇后凯茜、描埃及眼圈的萨丽以及唯一的大朋友鹭鸶儿之间像白纸一样单纯的友谊；胆小的她在餐厅里边哭边吃米饭三明治；一边照镜子一边想象电影中嘴唇红红的女主角……我的目光掠过清澈得像盛夏溪底的鹅卵石般的文字，指尖拂过被台灯注视过的、烘炉里的大麦面包一样温暖的纸页，似乎又触摸到了记忆里的那个，渴望长大的我，觅寻友情的我，怯弱的我，爱对着镜子冥想的我……细细咀嚼回忆，微笑不知不觉从嘴角泻出。

So we prove that Wojcickas conjecture can not come into existence when k=4.f denotes the minimum edges of domination k-edge-critical graph with n vertexes.

对于k=1和k=2，易知：Sumner猜想本文对奇数和偶数分别构造了k支配边临界图，给出了f的一个上界

The method is convenient to be used, especially to nonhomogeneous equations and nonhomogeneous boundary value problem.

用微分算子法给出了线性扩散方程和波动方程的通解及初值以及边值相关问题的算子解，特别是对非齐次方程和非齐次边界问题处理尤其简捷适用。

Firstly, we normalized the basic voxel by constructing its minimum oriented bounding box. Secondly, we constructed its D2 shape distribution curve, and computed the values of EMD(earth mover's distance) compared with the corresponding curves of the normal cone and cylinder respectively, and the corresponding top diameters. Finally, we compared the top diameters and obtained the parameters by the bounding box.

首先建立基本体素的MOBB，对体素进行标准化；然后生成其D2形状分布曲线，计算此曲线分别与标准圆锥体形状分布曲线、标准圆柱体形状分布曲线的EMD(earth mover's distance)值以及相应的上底直径；最后通过比较两个上底直径的大小来判断此体素是否为圆台体，并由包围盒的边长给出圆台体的参数。

This paper presents a study on modeling the stability of dump slope using the techniques of limit equilibrium, numerical simulation, and numerical differentiation.

The above presented methods are applied to solve the 2D harmonic equation. Numerical examples show satisfactory results.

对上述提出的方法，本文以二维调和方程的不同边值问题为例，推导出相应的计算公式，并在随后给出相应的数值算例，数值实验的结果是令人满意的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
