树

General Sherman is approximately 2,200 years old – and each year, the tree adds enough wood to make a regular 60-foot tall tree.

谢尔曼将军的年龄大概有 2，200 年——而且光他每年生长的木头可以变成一棵60英尺高的树，自然学者约翰姆尔对它的评价："此树集天地之精华，哥上下观之，应再无出其右者。"

General Sherman in California, is the biggest living tree, it is a giant sequoia over eighty three metres tall and has a trunk of eleven metres across.

这棵参天红杉有83米多高，枝干横扫十三米之宽。据知，最大的树是林赛溪树，它是棵庞大的红杉树。1905年被刮倒。

Moreover, for the treelike system with prescribed motion and the non-treelike system with closed-loop, the generalized coordinates aren't independent completely. Only the dynamical equations of the system and the constrain equations resulting from the prescribed motion and the closed-loop are combined to form DAEs, it can be solved.

另外，对于有指定运动的树系统或带有闭环的非树系统，系统的广义坐标是不完全独立的，系统的动力学方程要与指定运动或系统切断所附加的约束方程一起组成微分--代数方程组才能求解。

With analyzing structure features of sheet metal parts, the geometrical information model is built on the basis of the hierarchy of structure feature, structure element and geometrical element.

2分析了钣金零件的结构特征构成，建立了"结构特征—结构要素—几何要素"的三层几何信息模型，并采用树结构组织模型几何数据，分别给出了框肋零件、整体壁板零件和蒙皮零件的几何信息模型；分析了状态衍化中的结构要素变化类型和成形工序对结构要素变化的影响，采用加权图描述了状态衍化中结构树的变化；对应零件几何信息层次构成，建立了钣金零件结构特征的XML模式，分别举例说明了各层几何信息的XML表达，形成了基于XML的钣金零件数据表达方法。

Compared with traditional DEM or TIN based methods, this pure vector approach obtains not only the topological structure of drainage system in planar graph, but also the valley distribution polygon range. Depending on geometrical computation and judgment of vector line, polygon, the structured properties in drainage representation is enhanced, avoiding the case of noise disturbance in DEM based method. The core algorithm makes use of the ability of Delaunay triangulation in detecting hierarchical structure of each contour line.

中文摘要：基于Delaunay三角网模型在矢量等高线基础上通过弯曲特征分析，给出了一种地形结构特征提取及谷地树组织的方法，与传统的基于DEM或TIN数据结构提取地形特征的方法相比，该方法不仅得到了谷地系统在平面图上的拓扑结构，还获得了河谷在空间分布上的汇水范围，依托矢量线、多边形的几何关系判断，增强了谷地树组织中的结构化，避免了DEM方法中的噪音干扰，方法的核心是Delaunay三角网在单根等高线弯曲深度表达上的层次结构识别。

Exceptions to this condition are the famous "Three Trees": two Japanese Ceaders and a Gingko Biloba (Maiden Hair Tree or Salisburia Adiantifolia).

但三宝树是个例外，三宝树就是：两颗日本柳杉和一颗银杏树。

The use "presses the product to have three big advantage peony": One, affects slightly to the tree body, only must on the tree pole with knife girdling, spread smears "presses the line peony".

使用"促花王"产品有三大好处：一是对树体影响小，只需在树杆上用刀子环割一圈，涂抹上"促花王"就行。

Gingko, which also has other name such as Baiguo tree, Gongsun tree and longevity tree, had existed before glacial epoch. It is one of the oldest plants in the few survivors and one ancient and miraculous tree. Only China owns such kind of trees so it has the name "living fossil".

银杏树别名白果树、公孙树、长寿树，远在新生代第四纪冰河时期之前就已存在，是世界上最古老的孑遗植物之一；是一种古老而神奇的树种，为中国所特有；被誉为地球"活化石"。

MethodThe data about the oaktree rings fetched fromLab.of Globosity Eviroment Science College of Hokkaido Island University and the data of SOI publicized by NCEP were used to analyze the δ18O values of tree rings fromHokkaido Island by EMDmethod.

方法利用北海道大学地球环境科学学院实验室的橡树树轮资料和NCEP公布的1953～2002年的SOI资料，采用EMD法对北海道地区的树轮的δ18O进行分析。

Behind him I could see all the way down the narrow garden at the back of the house to the diagonal row of trees skirting the railway line-they are gone now, those trees, cut down to make way for a row of pastel-coloured bungalows like dolls' houses-and beyond, even, inland, to where the fields rose and there were cows, and tiny bright bursts of yellow that were gorse bushes, and a solitary distant spire, and then the sky, with scrolled white clouds.

在他的身后，沿着剧院后狭长的花园我能看到对角线排列的树那边的铁路线——现在没有了，那些树被砍倒了制作为那些蜡笔彩色的洋娃娃一般的小平房，甚至在内陆，在那儿有玫瑰园和奶牛，也有金雀花灌木黄色微亮的发光，一座孤单遥远的尖塔，然后就是天空，天空中卷着白色的云。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
