The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出，每个树种在树冠内相对高度上的叶量的垂直分布是不同的，天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小，约占10%左右；在树冠的中部以及中下部(0.4CL～0.8CL)，叶量所占比例最大，几乎集中了整个树冠60%～75%的叶量；而在树冠的下部(0.8CL以下)，几乎占很少的叶量，大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系，并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木，并不是传统意义上的全部竞争木；本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况，并采用等树冠投影面积法把树冠分为5级，这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想，用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型，设计了10个与林学意义相一致的约束条件，并采用0-1整数规划的思路，在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例，具体计算出了每株采伐木，经过择伐后，目标函数值按模型设计的要求发生了极大的改变，增加了5倍多，说明了最后这个解的优良性，满足了设计的要求。

Keyword index is a data structure that allows us to search in constant time for documents containing specified keywords. Unfortunately, standard index constructions are not designed for encrypted documents, because they may leak some information about the document. In this thesis, we propose two index structures called PRP-Index and P-Index which are designed for encrypted documents.

中文摘要关键字索引搜寻为一种加速文件关键字搜寻的一种架构，但是随著文件的安全性越来越受到重视，文件开始以加密的型态储存於资料库，但是目前的索引架构并没有针对加密文件作考量，也因此索引有可能会透露出文件的相关资讯，造成安全上的问题。

The research carried out an experiment of extracting water from inland limnetic wetlands using TM remote sensing imagery based on many arithmetic,and concluded that spectrum classification was the best among the area accuracy index,extraction accuracy index and visual effect index,the following was single band threshold and vegetation index method,however,multi-band relationship and water index method was the worst.

研究基于TM遥感影像，运用多种方法针对典型内陆淡水湿地的水体信息进行了提取实验，通过对实验结果的分析得出：在面积的准确性、提取的准确度以及视觉效果3种指标下，光谱分类法较其它方法效果要好，其次为单波段阈值分析法与植被指数法，较差的是多波段谱间关系法与水体指数法；影响提取效果的主要原因是湿地水体提取不够完全，这是由影像的分辨率及湿地特殊的水文条件所造成的，采用像元分解及多源遥感数据融合技术将成为提高水体提取精度的重要手段。

Efficacy was assessed using the Assessment in Ankylosing Spondylitis International Working Group criteria, the Bath Ankylosing Spondylitis Disease Activity Index, night pain, patient ' s global assessment, the Bath Ankylosing Spondylitis Functional Index, the Bath Ankylosing Spondylitis Metrology Index, chest expansion, the Mander enthesis index, the total swollen joint index, the C-reactive protein level, and the Short Form. 36 (SF-36) health survey questionnaire.

For example: Oracle may choose an index fast full scan instead of an index range scan because the compressed index is now much smaller, and your setting for parameter db_file_multiblock_read_count is large; or Oracle may choose to use an index and do a nested loop because the index is now 30% smaller, where previously it was doing a table scan and hash join.

由于压缩索引现在更小了，对参数db_file_multiblock_read_count也较大，那么Oracle可能选择一个index fast full scan而不是index range scan；或者由于索引减小了30%，Oracle选择使用一个索引和nested loop，而之前它用表扫描和hash join。

And such methods V/m ratio t-test, negative binomial parameter, index of dispersion, Cassie index, index of clumping, index of mean crowing and index of patchiness are employed to analyse various dominant populations of Heptacodium miconioides community in the Tiantai Mountain in Zhejiang province and distributive patterns of Heptacodium miconioides community in different quadrats, and this paper also examines the intensity of Heptacodium miconioides population in different quadrats by means of stand classes.

摘 要 以浙江省天台山七子花群落为研究对象，采用相邻格子样方法取样数据，应用方差／均值比的t检验法、负二项参数、扩散型指数、Cassie指标、丛生指标、平均拥挤指数和聚块性指数等方法，分析了七子花群落各优势种群以及七子花种群在各样地中的分布格局，并分立木级对七子花种群在不同样地内的集群强度进行了测定。

Based on the shortest path matrix of 20 cities, we have quantitatively evaluated the highway network development level of the region by the accessibility index, extension index, conglomeration index, and etc. The result shows that in the space structure the highway network development level is a "core-margin" model. The cities with higher accessibility indexes gather around Zhengzhou City, while those with lower ones distribute in the margin. The order among conglomeration index is accordant to that of accessibility index.

以通达指数、伸展指数、趋中指数等为衡量指标，以20个入网城市的最短路径矩阵为基础，对中原城市群区域高速公路网络的发育程度进行定量评价，结果显示：中原城市群高速公路网络在空间格局上呈现明显的"核心－外围"模式，通达指数最高的城市集中在中心城市郑州周围，较低的城市分布在外围地区，且趋中指数排序与通达指数排序相吻合。

The development of the index have catched up with the development of the economy and the society.We can ameliorate our index in many ways. We can fetch in new index,such as rewarding index of investment capital, it can be used to avoid the ruleless fluctuate caused by unregular revenue. We can fetch in the accrual ability of immateriality assets and "social responsibility" to enhance the deal of non-currency info and knewledge assets info. We can fetch in the method of key index analyse through relevancy analyse to conform the sequence of significance.

我们可以从多方面对指标进行改进，可以通过引进新指标如投资资本报酬率来克服因非经常性收益使企业业绩出现忽高忽低地波动的问题；可以通过引入无形资产获利能力评价指标、"企业社会责任"的概念来加强企业非货币性信息、知识资产信息在评价体系中的份量；通过引进企业获利能力关键指标的灰色关联分析来科学地确定指标的重要性顺序，以减少指标使用的盲目性。
