In this article made the cluster of phonological type by 4 of main phenophase with bourgeon period, leaf expansion period, flowering period and fruit ripenes period of observed data on phonology of 42 kind of plant 34 year in Minqin desert area, further the 23 of phenology classification merged by phonological type. The 23 of phenology classification basically obeys the ecotype characteristic of the plants, and the more scientific than the type of system cluster by plants sample. Moreover, the form of phonological type record by "ten day period + phonology" in the article.

以民勤荒漠区42种植物34年的物候观测资料，以萌动期、展叶期、开花期和果熟期4个主要物候期进行物候型聚类，进而将物候型归并为23个物候类型，聚合的物候类型基本上遵从植物的生态型特征，较系统聚类法直接用样本聚合的类型更加科学合理。

Landscape pattern analysis based on landscape metrics is a basic content of the research on landscape ecology. More and more researches proved that not only scale effects and the precision of remote sensed data had significant influence on landscape metrics, but also the difference of land use classification would make the change of landscape metrics. However, we still have not found out how land use classification affects landscape metrics and associated influence mechanism.

基于景观格局指数的空间格局分析是当前景观生态学研究的重要基础内容，不仅数据源准确度、尺度效应显著影响景观格局指数，土地利用类型划分也对景观格局指数具有显著影响，但我们对这种影响的总体理解尚很缺乏。

The conventional classification methods are hard classification based on the spectral statistic features of the pixels.

这些土地利用类型的波谱特征为进行土地利用分类提供了波谱理论基础。

But under limited training sample size, increased dimension of remote sensing data means decreased samples/dimension ratio, which can lead to low classification accuracy if common statistic based pattern classification methods were used.

但在有限训练样本条件下，遥感数据维数的增高使样本/维数比率大大降低，采用常规的统计模式识别方法反而无法得到较好的分类结果。

On the basis of the optimizing program,the microcomputer output of arranging the order of parts,the statistic of the classification of part names and the statistic of characteristic information of parts,and the classification of part groups using BASIC-Ⅱ language are pre- sented.

本文提出了实施成组技术中采用分类编码对产品零件分组的方法，分析了零件组特征矩阵制定的原则，在优化程序的基础上，提供了采用BASIC-Ⅱ语言的关于零件排序、零件名称类别及特征信息统计、零件分组的计算机输出结果。

New model utilizes grid computing technology,plans as a whole of network computing resources,combines with statistic classification advantage of support vector machine in finite sample space,probes into application of grid computation technology in image classification.

为了充分利用网格技术分布式、高性能、协同共享的能力，设计了一种基于网格和支持向量机的分布式图像分类器模型，采用网格计算技术，统筹网络运算资源，结合支持向量机在有限样本统计分类中的优势，探索网格技术在图像分类中的应用。

In the first approach the metadata extraction is viewed as a classification problem. Three statistic classification models, including Support Vector Machines, Perceptron with Uneven Margins, and Maximum Entropy are studied. The approach suffers from the problems of ignoring the variance in lengths of documents and ignoring the dependency of text units within documents. To solve the problems, our second approach takes the metadata extraction as a sequence data labeling problem and makes full use of the sequential information.

论文首先研究了基于分类的元数据抽取方法，考察了支持向量机、非对称间隔感知机和最大熵模型在ADME中的应用；然后针对分类方法中存在的忽略文档之间的差异、不考虑文档上下文等问题，提出了基于序列数据标注模型的抽取方法，并结合最大熵马尔可夫模型、投票感知机模型和条件随机场模型进行了研究；最后本文根据前两种方法的设计思想和优缺点，研究提出一种新的结构预测模型—— CDASP（Coordinate Descent Algorithm for Structure Prediction），并将其应用于元数据的自动抽取中。
