树枝

The previously tan and brown tones of the trees and the green hue of the leaves and ferns was replaced by vast debris fields left behind: a decaying, gray hued tangled mess of stumps, brush, and broken limbs, most of it at or below eye level.

过去苍褐的树木以及翠绿的叶子和蕨类，被取代为一片狼藉。溃烂灰色的残存树桩纠结一起，断掉的树枝散满一地，这些事物大部分都在或者低于眼睛的高度。

A girl named Maxi went off to whittle a branch with a hunting knife.

一个名叫马克西的女孩走到一边，拿着一把猎刀削起树枝来。

They followed this outward to where the riot of leaves caught the glare of Hyperion's sun.

他们沿着这条树枝走着，海伯利安的太阳光照在这些茂盛的树叶上。

If an individual is crossing alone in swift current, he can keep his balance best by using an ice ax or a sturdy tree branch as a third point of support for contact to the stream bottom upstream from his feet.

如果一个人要通过水流很急的溪谷时，使用冰斧或强固的树枝当作第三个支撑点，称在上游方向，这样能提供最佳的身体平衡。

But it is crowded, Ilex is, bending the waist down branches.

但它密密麻麻，满树都是，压得树枝弯下了腰。

One day a hungry robin saw an inchworm, green as an emerald, sittingon a twig.

有一天知更鸟看到一只翠绿的尺蠖坐在树枝上。

Many a village Bose, fit only to course a mud-turtle in a victualling cellar, sported his heavy quarters in the woods, without the knowledge of his master, and ineffectually smelled at old fox burrows and woodchucks' holes; led perchance by some slight cur which nimbly threaded the wood, and might still inspire a natural terror in its denizens;—— now far behind his guide, barking like a canine bull toward some small squirrel which had treed itself for scrutiny, then, cantering off, bending the bushes with his weight,imagining that he is on the track of some stray member of the jerbilla family.

许多村中的牛，行动迟缓，只配在储藏食物的地窖里追逐乌龟的，却以它那种笨重的躯体来到森林中跑跑跳跳了，它的主人是不知道的，它嗅嗅老狐狸的窟穴和土拨鼠的洞，毫无结果；也许是些瘦小的恶狗给带路进来的，它们在森林中灵活地穿来穿去，林中鸟兽对这种恶狗自然有一种恐惧；现在老牛远落在它那导游者的后面了，向树上一些小松鼠狂叫，那些松鼠就是躲在上面仔细观察它的，然后它缓缓跑开，那笨重的躯体把树枝都压弯了，它自以为在追踪一些迷了路的老鼠。

All branches are connected to the sturdy trunk of his decision-making tree, an inviolate set of rules for risk control.

所有的树枝都连接到他强大的决策树，决策树就是一系列控制亏损的原则。

We dedicate all our crafts to June, for it is he who taught the People to bend the branches of trees to make our bows, and to fashion coverings of furs and ironbark.

我们的制造工艺全部来自于June，他教导了人们如果通过弯曲树枝来制造弓箭，以及用毛皮和铁皮木做铺盖的方法。

In this paper, firstly, not only the incidence matrix ,adjacent matrix, cycle matrix, cut-set matrix of an undirected graph are summarized, but also the close contact between a graph and its corresponding matrix are discussed ; secondly, many problems of a graph which are solved by analysing its matrix are listed as follows:1、The co-tree set of a graph is obtained by using its cycle-matrix ; 2、The branches of its spanning tree are given by using its cut-set matrix ; 3、By making use of the incidence matrix of a graph ,not only its vertex cut 、cut vertex 、isolated point and spanning tree can be obtained ,but also the two sides which are whether parallel or not can be judged ;4、By using their adjacent matrix ,the two graphes which are whether isomorphous or not can be judged; once more, there is a detailed introduction in view of special graph (for example: bigaritite graph ,regular graph and so on);last but not least, a graph method of calculating the N power of a matrix is given and the practical applications of the theorem for degree is indicated.

本文首先综述了无向图的关联矩阵，邻接矩阵，圈矩阵，割集矩阵以及图和它对应矩阵之间的关系；其次总结出了利用上述各类矩阵可以解决的图的若干问题：1、利用图的圈矩阵可以求其连枝集；2、利用图的割集矩阵可以求其生成树的树枝；3、利用图的关联矩阵不仅可以求其割点、点割集、连通度、孤立点和生成树，而且可以判断两条边是否平行；4、利用图的邻接矩阵可以判断两个图是否同构；再次，针对特殊图（例如：二分图、正则图等等）的邻接矩阵作了详细介绍；最后，得到了利用图计算矩阵的N次幂的方法，指出度数定理的实际应用。
