It also concludes that the classification result is obviously better using C5.0 decision tree algorithm based on the combining data processed by a sequence of atmospheric correction, data fusion and transformed by NDVI, NDBI and Tasseled Cap than the raw data.

研究发现，C5.0决策树算法用未处理的资料生成决策树的效果较差，而经大气校正和数据融合后计算出NDVI、NDBI及缨帽变换的前3个分量的组合数据生成的决策树深度最小，并且分类精度最高。

The basic concept and general knowledge of data mining were given firstly, and the characteristics and research methods of data mining procedure were explained based on the test-driving database of WS9 aero-engines. Rough set and decision tree, these two classification mining methods were used to extract decision rules, regression analysis was utilized to find the relationship between variables, and the tendency also was predicted.

论文阐述了数据挖掘技术的基本概念和一般知识，分析了基于WS9发动机试车数据库数据挖掘的特点和研究方法，选择了粗糙集和决策树分类挖掘方法提取决策规则，利用回归分析方法发现变量之间的函数关系，并进行趋势预测。

Three types of cuticular thickening at the polar region of the guard cells are observed: slight cuticular thickening; rod-shaped culicular thickening and rarely T-shaped thickening.With data obtained from the former research and personal observation, the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted byout-group comparison using, the related genus Kadsura. as result, a new system of the genusSchisamdra Michaux was reconstructed, and Schisandra Michaux was subdivided into 2 subgenus, 3 section, 2 series 10 species in this dissertation.

整理有关五味子属植物研究的资料，补充搜集近期发表的资料和本人研究所得数据，以种为基本单元，选择近缘的南五味子属作为外类群，采用PAUP4.0b4a软件对本研究得出的性状数据作分支分析，重建五味子属的系统发育，修订和补充五味子属分类系统，在五味子属下设2亚属、3组、2系、10种。

Based on the field survey of Jiufeng Forest Park,the paper has analysed the importance,necessity and purpose of setting up the system and generalized research steps and technology route;the paper has discussed theory

这样，利用计算机技术来系统的管理鹫峰的旅游资源信息，把各种旅游资源信息分类存储，保证了数据资料管理工作的高效性及正确性；提高了管理人员的工作效率，减少了工作量；便于更好的管理和规划鹫峰森林公园，最终达到旅游资源管理工作的信息化；也为今后建设国家级旅游资源数据库提供基础数据；对鹫峰森林公园的可持续发展起到了一定的促进作用。

A series combined test method tests were performed to determine the liquid-plastic limits of different samples of fine grained soil and silty sand. The result showed that the loglog relationship between the depth of penetration of fall cone and the water content of some samples were clearly not linear, and the liquid-plastic limit could not be obtained according to the linear relation. Effective test data could not be measured within the three arranges of water contents proposed by the present standards. The dependability was necessary to discuss about the liquid-plastic limit test results obtained from three arranges.

采用液、塑限联合测定法针对部分细粒土和粉砂进行液、塑限测定时，发现对于部分细粒土在双对数坐标上圆锥下沉深度与含水率之间的关系并非线性关系，无法依据线性关系确定液、塑限：采用规程建议的三个含水率范围有时根本无法获得有效试验数据；采用规程建议的三个含水率范围确定得到土的液、塑限试验结果的可靠性有待商榷；采用直线段试验数据确定的液、塑限进行分类可能出现相互矛盾甚至错误的结果。

The time series analysis presented in this paper may have a good value on research about how to make the best of time series remote sensed data and land cover classification. Distill 16 metrics from the SPOT4-VEGETATION/NDVI data and NOAA/ Ts data. The metics reflect the seasonal variation. We futher classify the reasearch area based on the 16 metrics.

通过时间序列分析方法，从SOPT4-VEGETATION/NDVI数据和NOAA/AVHRR提供的Ts数据提取16类季节性动态变化参数，并结合16类参数对研究区中混分类型进一步区分，最终得到理想的分类效果。

The technique of data generalization and attribute relativity analysis are also adaptive for other data minging models,such as decision-tree algorithm.

本文用到的数据概化技术和属性相关性分析技术，同样适用于除神经网络模型外的其他数据挖掘模型中输入变量与输出变量的关系分析，如：决策树算法中的分类问题。

In this paper,the storage forms of sound and image information are first discussed.Then,the authors study and analyse methods and technology that can be used in sound and image retrieval,and give classified expositions.Meanwhile,this paper makes comparative research on data models of the multimedia information retrieval system,proposes that the design of MIRS may base on a RDB system,and it can support storage and retrieval of sound and image information by expanding its ability of managing complex objects and multimedia data.

本文首先分析了声音与图像信息的存贮处理，接着分类阐述了声音、图像信息检索可以采用的方法和技术；在此基础上，对多媒体信息检索系统的数据模型进行了比较研究，提出在目前技术条件下，多媒体信息检索系统的设计可采用现有成熟的关系数据库系统作为基础，并在关系模型里增加处理复杂对象与多媒体数据的能力，以实现对声音、图像等多媒信息的存贮与检索。

Monte Carlo is a method that approximately solves mathematic or physical problems by statistical sampling theory. When comes to Bayesian classification, it firstly gets the conditional probability distribution of the unlabelled classes based on the known prior probability. Then, it uses some kind of sampler to get the stochastic data that satisfy the distribution as noted just before one by one. At last, it can obtain the posterior probability distibution of each unlabelled classes by analysing these stochastic data.

蒙特卡罗是一种采用统计抽样理论近似求解数学或物理问题的方法，它在用于解决贝叶斯分类时，首先根据已知的先验概率获得各个类标号未知类的条件概率分布，然后利用某种抽样器，分别得到满足这些条件分布的随机数据，最后统计这些随机数据，就可以得到各个类标号未知类的后验概率分布。
