This small weakening of the sun, however, has been outpaced by the rapid increase in CO2 levels from all our fossil fuel burning and tree-cutting.
虽然太阳活动降低了，但是我们燃烧化石燃料和砍伐树木引起了CO2的快速升高。
Further simplification is possible; notice how this only simplifies at the bottom levels of the tree?
还可以再进一步简化；注意一下：它是如何实现只简化树的最底层的？
A FOT index is an index that is similar to a B-Tree index, but an FOT index has multiple root nodes and fewer levels. (B-Tree indexes have only one root node and more levels.)
FOT索引类似B - Tree索引，但它有多个根节点和较少的级(B - Tree索引只有一个根节点和更多的级)。
Figure 34 shows a project tree on the left and a compact view of the hierarchical levels of the composed process on the right.
图34的左边显示的是一个项目树，右边则是组合流程各层级的精简视图。
Levels - Number of levels in the b-tree.
levels -B -树中的级数。
The decision tree constructed with the new standard of attribute selection has the following characteristics: fewer leaf nodes, fewer levels of average depth, better generalization of leaf nodes.
用新的属性选择标准生成的决策树一般具有叶子数目较少，叶子的平均深度也较小，且叶子具有较强的泛化能力。
In this logical approach, data units are structured in multiple levels that graphically resemble an "upside down" tree with the root at the top and the branches formed below.
该逻辑方式中，数据单元的多级结构类似一棵“倒立”的树，该树的树根在顶部，而树枝向下延伸。
Climb the Great Tree and use your wits to keep unlocking levels. See who can climb the highest!
用你的智慧与手指解锁关卡，看看谁才是丛林水果大王！
This paper proposes the method of decision-tree SVM on two levels pyramid image, it could solve the segmentation problem of multi-classes objects on aerial image.
提出了两级金字塔影像上的决策树支持向量机方法，解决航空影像中多类地物的分割问题。
You can configure the treeview to show multiple levels of navigation that show navigation links to child pages in a tree hierarchy.
您可以对该树视图进行配置以显示多级导航，它将以树层次结构显示指向子页面的导航链接。
To gauge precipitation, they looked at tree ring widths in lower-elevation oaks, which grow faster in years with higher levels of rainfall.
而为了测定降水量，他们则对长在低海拔地区的栎树的年轮宽度进行研究，因为这些树在雨水比较充沛的年份长得更快。
