In this thesis, our research work mainly focuses on the following aspects: 1, To the question of the large depth of the tree structure of scene database in building environment, and need take much time on search node, to table a proposal of regularization restrictions on the BSP tree construction, for the sake of obtaining balanceable BSP tree, to improve the system efficiency.

本文的主要研究工作如下：(1)针对室内环境场景数据库的树型层次结构深度比较大，进行节点搜索时花费的时间比较大的特点，提出对BSP树的构造进行规则化限制，得到较为平衡的二叉树结构，来提高系统运行过程中对BSP树进行遍历的效率。

The tree T=is a bichromatic tree subgraph in a maximal plannar graph G, in which the subgraph induced by V_t is a tree and T is a component of some bichromatic subgraph Gij of some 4-coloring of G.

"And I may add," said Herbert,"that the eucalyptus belongs to a familywhich comprises many useful members; the guava-tree, from whose fruit guavajelly is made; the clove-tree, which produces the spice; the pomegranate-tree, which bears pomegranates; the Eugeacia Cauliflora, the fruit of whichis used in making a tolerable wine; the Ugui myrtle, which contains anexcellent alcoholic liquor; the Caryophyllus myrtle, of which the barkforms an esteemed cinnamon; the Eugenia Pimenta, from whence comes Jamaicapepper; the common myrtle, from whose buds and berries spice is sometimesmade; the Eucalyptus manifera, which yields a sweet sort of manna; theGuinea Eucalyptus, the sap of which is transformed into beer byfermentation; in short, all those trees known under the name of gum-treesor iron-bark trees in Australia, belong to this family of the myrtaceae,which contains forty-six genera and thirteen hundred species!"

&我还要补充一句，&赫伯特说，&有加利树的这一科包括很多有用的种类，其中番石榴的果实可以制造果子酱；丁香树出产香料；安石榴树结安石榴；桃金娘丁香树的果实可以酿造美酒；乌葛杨梅树含有很浓的酒精成分；石竹科的杨梅树皮可以制成珍贵的肉桂；尤琴椒树可以制造牙买加辣椒；普通杨梅的嫩芽和果子里有时可以提取胡椒。有加利树可以提供一种香料，几内亚有加利树的树液经过发酵可以制成啤酒。一句话，澳大利亚所有的橡皮树和铁皮树都属于这种桃金娘科，它包括四十六属和一千三百种。&

The obtained results show:After applying Yelükang ball fertilizer,the active iron in the chlorotic fruit tree leaves increased by 8.7%~20.2%,the chlorophyll content of apple tree increased by 18%;the chlorotic degree of fruit trees decreased 2~3 scales,the yield per tree increased by 56%~89%.

研究结果表明：施用叶绿康球肥可使失绿果树叶片的活性铁提高8.7%～20.2%，苹果叶片的叶绿素含量提高18%；果树失绿程度降低2～3级，果实单产提高56%～89%。

Based on the development, classification, comparation of classific algorithms of spatial indices, the paper designs two efficient spatial indices including the improved quadtree and R+tree, applies them into spatial query processing, and realizes the spatial select query algorithm based the improved quadtree and R+tree, and nearest and k-nearest neighbour query based R tree.

在对空间索引技术的发展、分类和典型算法比较的讨论基础之上，本文设计并实现了两个高效的空间索引—改进的四叉树索引和R+树索引，并将这两个索引应用到空间查询处理中，分别实现了基于改进四叉树和基于R+树的空间选择查询算法以及基于R树的最临近查询和K最临近查询算法。

The thesis is based on income question, forest coverage rate and grop production.to beging with, date envelopment analysis is proved that it can be applicated into grain for green in shan-bei district, and then in view of the fact, seven esential factors which have influence on the project are found out: expense of dam, expense of crop,expense of cash tree ,expense of defense tree,other economic crop,expense of grass and graziery;and the output factors include:income of gdp,pure income per captia,the area of decreasing land loss,graziery income ,crop production,income of tree,the totle income of economic crop.after the date of each facts are puted into dea model,unefficiencial decision making units found.the data that are got through adjusting unefficiencial dmus dy dea can offer guide in shanbei district upgrading of an industrial structure.at the same time ,taking into account some possible problems in or after grain for green in shan-bei district,the thesis bring out some propesal to improve the circumstance,enhance the life level and putthe relation of population,resource and circumstance into a healthy orbit.

论文以解决陕北地区的收入问题，植被问题以及粮食产量问题为出发点，首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性，然后结合陕北地区目前的实际情况，综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标：水利水保设施投入，农作物投入，经济林种支出，防护林支出，其它经济作物，草类支出，畜牧业投入；以退耕还林所要解决的最终问题作为输出指标：GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后，通过分析求解得出非有效的决策单元，再运用包络分析方法的一些基本原理对非有效的决策单元进行调整，由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时，又针对陕北地区在退耕还林过程中以及之后可能面临的困境，提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善，使农民尽快脱贫致富，使人口、资源、环境的关系尽快纳入良性循环的轨道上。

This model uses nonlinear mapping to map samples into high dimensional feature space, and compares the distribution of each type of samples in the high dimensional space. So that a binary decision tree is constructed through clustering, which can make the more separable classes classified at the upper node of the binary decision tree. The model overcomes the accumulation of misclassification and avoids the condition of impartibility efficiently. At the same time, each node of decision tree uses binary least squares wavelet support vector machine to obtain higher generalization ability.

该模型利用非线性映射将样本投影到高维特征空间，比较每类样本在高维空间的分布情况，进行聚类构造出一个二叉决策树，使容易区分的类别从根节点逐层分类出来，有效克服了错分积累和避免不可分情况；同时，各个节点采用二值最小二乘小波支持向量机，以获得较高的泛化能力。

Pass the person of here along with a way of escape, see there is money on large tree, thinking is divine tree, also register oneself fund on the tree in succession then, obtain more fund with invocatory some day, from now on what people formed a ready source of money is consuetudinary.
