再请E高手翻译一下，谢谢(10分)

Lines
Lines within your tree can provide a greater visual effect and make larger tree structures easier to read. The negative effect on having lines within your tree is performance. A tree with 100 items may use about 300 images just to display the relationship between entities. Caching and preloading images can help, but they still exist as individual objects within thedo
M. Without lines, simple indenting can show the relationship between parent and child. In this article I will demonstrate the creation of a tree without lines.

Lines（线索化，没有上下文，而且我对dom没有研究，呵呵，借鉴数据结构就这样叫了，但是感觉不太好）
Lines within your tree can provide a greater visual effect and make larger tree structures easier to read.
对树（内部节点）进行线索化可以提供一种更有效的可视化效果，即使更大型的树结构也很容易让人理解。
The negative effect on having lines within your tree is performance.
然而树（内部节点）线索化的负面效应也是显而易见的。
A tree with 100 items may use about 300 images just to display the relationship between entities.
比如说，含有100个节点（此处是不是应该理解为item=node？）的一棵树大约至少需要300个图像才能表现出这些实体之间的关系。
Caching and preloading images can help, but they still exist as individual objects within thedo
M.
通过高速缓存和预加载图像可以获得一定程度的补救，但是它们却作为单独的对象存在于DOM（文档对象模型）中。
Without lines, simple indenting can show the relationship between parent and child.
如果不借助线索化，简易的标记也能够表现出父节点与子节点之间的关系。
In this article I will demonstrate the creation of a tree without lines.
在本文中，我将说明（证明？）不含有线索化的树的创建。
e文水平真的差，感兴趣而已，抛砖引玉。

学习！

我来一个，香槟妹妹! 条件是给我倒一杯。:=)

线
Lines within your tree can provide a greater visual effect and make larger tree structures easier to read.
在树形视图中的线条可提供较好的可视效果，且使得大的树形结构易读。
The negative effect on having lines within your tree is performance.
用线条的负面影响是降低了效率。
A tree with 100 items may use about 300 images just to display the relationship between entities.
一个拥有100个项目的树形视图中大约要用300幅图像来显示元素之间的关系。
Caching and preloading images can help, but they still exist as individual objects within thedo
M.
缓存和预载图像会有所帮助，但在DOM里它们依然以独立的对象存在。
Without lines, simple indenting can show the relationship between parent and child.
没有线条时，简单的缩进也能显示出父子关系。
In this article I will demonstrate the creation of a tree without lines.
在本文中我将演示没有线条的树的创建。

香槟女孩恐怕是个男的吧？

BA:好像E文很强啊
AGUI：不给你分了，因为看了第一行，线索化绝对不能翻译为线吧……

CJ: 版主大侠这样说，我好伤心，毕竟是您说了算，因为您是版主:=)。
但我还是想申辩一下：其实这里并不牵涉数据结构的事。只是说用线条来在界面上表示树形结构而已啊，为什么一定要说成线索化呢？
