A total of 29 groups of isotope age data such as Sr-Nd isotope age data and Nd model age data of igneous rocks, including granites, volcanic rocks, dyke swarms, cumulates, and ophiolites, formed in different periods of time are reported in this paper, which show the following two features:(1) igneous rocks including ophiolites formed in this area since 800 Ma BP all have high eNd and low Sri, with most Sri values centered in the range of 0.7045 to 0.7060 and eNd values in the range of 1 to 5, and (2) most of the TDM ages are in the range of 800 to 600 Ma, with only a few at 1000 Ma.

TDM年龄较多集中在800 ～600 Ma，个别为1000 Ma。

The new system directly digitalizes the strain signal assembles the data into a data package and then transmits it outside via infrared. As well as increasing infrared intensity increasing data transmission speed with the help of these measures, the reliability of the new system is greatly enhanced.

新系统通过对活塞应变信号的现场数字量化，数据以数据包的形式发送，增大红外发射电流，提高数据传输速度，使新测量系统在恶劣的工作环境中，数据传输的可靠性大大提高。

Considering that magic cube is easy to disarrange and hard to solve, I designed the Magic Cube Stream Cipher: the main part is a virtual cube filled with data; by turning the magic cube many times, original data are disarranged and new ones are generated; new data serve as current secret key, which is a part of the key stream.

我根据魔方&打乱容易恢复难&的特性，设计了魔方流密码算法：主体是一个由数据构成的虚拟魔方；利用多次魔方变换改变数据&魔方&的整体状态并生成新的数据；以此作为本次加密运算的密钥。

Subsequently, clustering analysis in data mining is disserted, involving the methods and characteristics of clustering used in data mining and the methods for evaluating the clustering results, with emphasis on clustering the data with categorical attributes.

在此基础上对数挖掘中的聚类分析作以详细地论述，总结了数挖掘中聚类分析的方法和特点，并对聚类结果的评价方法进行了讨论，重点讨论了分类属性数据聚类，具体研究了k-modes 算法及其变形，并指出了它们的优缺点。

The dissertation focused on the technologies, algorithm and application of WBSDM, and the main studies and new contributions are described as follows: 1. Technologies of spatial data mining and web-based data mining are summarized and then the concept of WBSDM is put forward and its main functions and meaning of research are disserted in detail. 2. The framework of web-based spatial data mining is presented. And its background, definition, features, functions, system structure, implementation strategy, key technologies and so on are illustrated systematically.

本项研究旨在总结空间数据挖掘技术和基于Web的数据挖掘技术及WBSDM的应用前景；系统地提出基于Web的空间数据挖掘框架；设计基于XML/J2EE的WBSDM平台模型；将MAS(Multi-AgentSystem)技术引入WBSDM并提出应用策略；研究基于粗糙集的空间知识库刻画模型，提出并实现高维数据的特征提取和数据浓缩算法；提出并实现基于知识库的知识发现模型；构造一个WBSDM的原型实验系统，对本文的相关研究进行验证。

For example, the object is composed of four blocks, i.e. block A, B, C, D. Block A locates the left of block B and above block C. According to order, its code is ABDC etc. This code does not change its order after the object rotates, zoom, downsizes. The disadvantage of this method is that it will lose the target when the color is changed.A video fluid is composed of compressed data which include I, P and B(bi-prediction) frame. The data of each block of P frame is predicted by motion prediction and compensation from the data and motion vector of I frame.

MPEG视频流由I、P、B组成，为减少空间、时间的冗余，P帧的数据来自已经解压缩的I帧和P帧，B帧的数据来自已经解压缩的I帧和P帧或者P帧和P帧，这些需要解码的图像通过运动预测和补偿对P帧／B帧进行解码，P帧／B帧中每一个宏块的数据来自于最佳匹配的相应I帧和P帧或者P帧和P帧中，以及图像变化而必须的运动补偿。

He pretreatment in course of algorithm includes the function of transforming of original data, eliminating unwanted data and educing needed data, etc.

算法过程中的预处理包括原始数据的格式转换、剔除冗余的数据及导出所需数据等功能。

With the increasingly development of Network Technology, the data must be enciphered to protect from being intercepted or modified. So, the security of Computer Data Communication became a focus of our society, which leads to the development of encryption and deciphering technique of Computer Data Communication Security.

随着网络技术的不断发展，为了保护数据在传递过程中不被别人窃听或修改，我们必须对数据进行加密，从而计算机数据通信的安全问题也就成为当今网络社会的焦点，也自然导致了加密、解密等一系列关于计算机数据通信安全技术的产生和发展。

Synthetic Aperture Radar is the more ideal remote sensing tool to survey the range of flood area;SPOT image data is applied to land use classification.It arranges two kinds data and computes the total area and the land use type of flood zone,and excepts to bring humanistic,social and economic data into the flood management system.It can help the operation and development of flood disaster prevention system.

合成孔径雷达为测绘洪水区域范围较为理想可行的遥测工具；而SPOT卫星影像资料则是应用于土地利用分类上，以GIS整合两种资料并计算出洪泛区域之总面积及其土地利用形态，期能将人文、社会及经济等资料纳入洪水管理体系之发展，有助于水利防灾整套系统之运作。

This research is a qualitative research, where method of the analysis of relevant documents and secondary analysis were adopted. The organization of data collection followed three steps of collecting data, excerpting data and building archive.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
