查询词典 evolutionary tree

Like a palm tree in En-gedi, like a rosebush in Jericho, Like a fair olive tree in the field, like a plane tree growing beside the water.

我高峻，如恩革狄的棕树，有如耶里哥的玫瑰树。我好象平原上一棵美丽的橄榄树，又像一棵耸立在街道溪畔的白杨。

The multicast routing problem that finding the minimum cost multicast routing tree with many QoS constraints may be formalized to Steiner tree problem in network, which is a NP-complete problem that an algorithm that finds a Steiner tree can not get the best solution in polynomial time.

寻找有多个QoS约束的最小代价组播路由树可以形式化为网络中的Steiner树问题，它是一个NP完全问题，在多项式时间内不能得到最优解，因此研究者所寻求的是一种次优的、在最差情况和平均情况下的性能都接近于最优的解决方案。

A tree whose hungry mouth is prest against the earth's sweet flowing breast; A tree that looks at God all day, And lifts her leafy arms to pray; A tree that may in summer wear A nest of robins in her hair; Upon whose bosom snow has lain; Who intimately lives with the rain.

一棵张着饥饿嘴巴的树，紧压在大地甘美而流畅的乳房上；一棵整天望着神的树，举起枝叶繁茂的手臂来祈祷；一棵树在夏日里可能戴着一窝知更鸟在头发上；雪花堆积在她的怀抱里；雨水也和她亲切地生活在一起。

A tree whose hungry mouth is prest againsr the earth's sweet flowing breast; a tree that looks at god all day, and lifts her leafy arms to pry; a tree that may in summer wear a nest of robins in her hair; upon whose bosom snow has lain; who intimately lives with rain.

一株树，他的饥渴的嘴吮吸着大地的甘露。一株树，他整日望着天高擎着叶臂，祈祷无语。一株树，夏天在他的发间会有知更鸟砌巢居住。一株树，白雪躺在他胸上，他和雨是亲密的伴侣。

A tree whose hungry mouth is prest Against the earth抯 sweet flowing breast; A tree that looks at God all day, And lifts her leafy arms to pray; A tree that may in summer wear A nest of robins in her hair; Upon whose bosom snow has lain; Who intimately lives with rain.

一棵树将她饥渴的口腔紧贴大地温情畅流的胸膛；一棵树整天爷望着上帝，举着她祈祷状的多叶手臂；一棵树也许在夏季戴上一个知更饭鸟巢在她的发丛里；皑雪曾落在她怀抱里，她和雨相处亲密。

A tree whose hungry mouth is prest againsr the earth's sweet flowing *; a tree that looks at god all day, and lifts her leafy arms to pry; a tree that may in summer wear a nest of robins in her hair; upon whose bosom snow has lain; who intimately lives with rain.

我向，永远不会看到一首诗，可爱的如同一株树一样。一株树，他的饥渴的嘴吮吸着大地的甘露。一株树，他整日望着天高擎着叶臂，祈祷无语。一株树，夏天在他的发间会有知更鸟砌巢居住。

Trees Page 2 of 21 By Joyce Kilmer I think that I shall never see A poem lovely as a tree ; A tree whose hungry mouth is prest Against the earth's sweet flowing breast ; A tree that looks at God all day , And lifts her leafy arms to pray ; Anest that may in Smmer wear Anest of robins in her hair ; Upon whose bosow has lain , Who intimately lives with rain .

作者通过对树的赞美来讴歌造物的神奇。小树自得天机自长成，于不经意中已经使得诗人的才情在大自然的佳作前自叹弗如。想来，我永远找不到一首诗像树一样美妙。树的饥饿双唇紧偎大地把甜美的乳汁尽情吮吸。树整天仰望着上帝，祈祷时，举起枝叶扶苏的双臂。夏天，树还会把知更雀的小巢 Page 3 of 21 戴在自己发梢。雪花在树的怀抱里冬眠，树和雨露更是亲密无间。

Then the spatial index is constructed which includes not only the external approximate expression but also interior approximate expression of spatial object and is extended from tranditional index only with external approximate expression. The index structures of MR-tree and MRD-tree based on multi-approximate expression are set up with the prototype index of R-tree, and the relevant algorithms about the index of insertion, deletion and search are provided. Then, the efficiencies of constructing index based on the multi-approximate expression and window range query are analysised and compared. In addition, the several algorithms and efficiency of soving the maximum enclosed circle and maximum enclosed rectangle are discussed and analyzed during constructing index based on multi-approximate expression.

首先，论文讨论了空间数据的特点、空间数据库的关键技术以及空间对象间的拓扑、距离以及方向关系，分析了空间对象的外部和内部近似表达，然后将传统索引中只利用空间对象的外部近似扩展为既有空间对象的外部近似又有空间对象的内部近似，即以空间对象的多重近似来构建索引，并以R-tree为索引原型构建基于多重近似的MR-tree和MRD-tree索引结构，然后给出了相关索引的插入、删除及查找算法，并通过实验比较分析了基于多重近似索引与基于外部近似索引的构建效率及窗口范围查询效率。

Rain on little tree, tree, tree.

落在小树上呀

In the ER-Tree, the efficiency of retrieval could be improved by the ways of partition of the vector space with hyper-sphere and R*-Tree s re-insert technology introduced to enhance ER-Tree s capability to represent the data-sets'features.

该索引树用超球体划分多维向量空间，以有利于计算最近邻；吸取R*-Tree树的重插技术，以增强索引树对数据集整体特征的表达能力，从而提高检索效率；通过引入插入安全点和删除安全点概念，有效地提高建树的效率。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
