查询词典 China 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; 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。

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。

Major results were summarized as follows:(1) A total of 58 tree species from 53 genera in 36 families among which 8 species were Rosaceae, 5 species were Liliaceae, 5 species were Eriaceae, 3 species were Ranunculaceae, 3 species were Compositae, 2 species were Cupressaceae, 2 species were Caprifoliaceae, 2 species were Umblliferae, and other 28 tree species were only one receptively. These were recorded in the 8 plots of the A. georgei var. smithii forest;(2) Number of families, genera, species and Margalef index correlated negatively with altitude (P.05), with a peak at 3600 m.(3) Shannon-Wiener index correlated negatively with altitude (P.01), and maintained stable at the altitudes between 3700~4100 m, evenness with altitudes, however, this trend was insignificant.(4) Jaccard index increased sharply with increasing altitude at the altitudes between 3600~4100 m, and was lower between different vegetation types at the altitudes between 4100~4200. Cody index β(subscript c decreased with an increasing altitude, but there were 2 troughs between 4000~4100 m and 4200~4300 m.(5) Maximum tree height H(subscript max and HH(subscript max=37 mcorrelated negatively with altitude (P.05); but basal area and BA BA(subscript max=5.3m^2 correlated with altitudes, however, this trend was insignificant.

结果表明：(1)在调查的8个急尖长苞冷杉林样地内共有植物58种，分属于36科53属，其中植物较多的科有蔷薇科8种、百合科5种、杜鹃花科5种、毛茛科3种、菊科3种、柏科2种、忍冬科2种、伞形科2种，其余的28科各只有1个种；(2)物种科、属、种数、Margalef指数D(下标 M与海拔存在显著的负相关性(P.05)，在分布急尖长苞冷杉最低海拔3600m处出现物种丰富度的最大值；(3)多样性指数与海拔之间有极显著的负相关性(P.01)，并且在3700~4100m之间多样性指数保持稳定；均匀度指数与海拔梯度之间存在负相关性，但不显著；(4)Jaccard指数C(下标 j在海拔3600~4100m随海拔的升高而升高，在生境过渡带的4100~4200m之间Jaccard指数C(下标 j较低；Cody指数β(下标 c随海拔的升高呈下降的趋势，但在4000~4100m和4200~4300m 海拔区间出现2个低谷；(5)最大树高H(下标 max和最大胸径DBH(下标 max与海拔之间存在显著负相关性(P.05)；胸高断面积之和和立木密度与海拔之间存在负相关性，但不显著。
