Target discrimination is a key technique in missile defense system, and after analyzing the defense system configuration, an integrated target discrimination mathematical model based on recursive temporal-spatial data fusion is performed, which brings the expert knowledge, environmental information and measure information into the integrated discrimination flow.

摘要目标识别是导弹防御系统的支撑技术，本文参考导弹防御系统配置，建立了基于时空信息序贯融合的综合识别数学模型，将专家知识、环境信息以及测量信息共同纳入综合识别流程。

More and more practical data in sensor network、communication、Internet flow analysis and Web log etc, are transported from teledata sources. Therefore, we need to construct the middleware of distributed query processing for data streams to support above application.P2P technique is used to build a huge distributed network for the processing of large number of information by internet terminals.

现有的数据流的研究主要为集中式的流数据系统，而数据流的本质是分布式的，越来越多如传感器网络、数据通讯、Internet流量分析和Web日志等的大量数据都来自不同的远程数据源，因此，需要构建分布式数据流查询处理的中间件以支持上述各种应用。P2P技术利用互联网的终端机来建立一个庞大的分布式计算网络，并对迅速涌出的大量信息进行处理。

Data of water and rain received by telemeter device can be real-time and dynamically reflected on WebGIS platform by diagram of curves,and it supplies an open information spaces for sharing geo-data.

该系统使遥测设备接收到的水雨情数据在WebGIS平台中电子地图相关监测点实时、动态反映，并且能够以曲线图等直观图形式表现出来，为水雨情动态监测信息共享提供了开放的信息空间，从而辅助工作人员进行正确与及时的决策。

The borehole televiewer can be used to identify lithology and fractures in open boreholes. The image data not only provide geological data of a study area, but also bring information to arrange test sections of hydraulic tests.

有鉴於此，本文介绍岩盘工址水力特性之调查方法，藉由整合孔内影像探测设备及双封塞水力试验设备达到岩盘工址水力特性调查目的。

It requires not only a first class tourist facilities and first-class travel service for a strong backing, but also need to provide around the natural tourist information, cultural tourism and the construction style of travel information data.

因此它不仅需要有一流的旅游设施及一流旅游服务作坚强的后盾，而且更需要各地提供自然旅游资料、人文旅游资料以及建设风貌旅游资料。

This system can complete quickly,the realtime parametric design of turbojet,turbofan,turboprop and turboshaft engine and its parts.During designing the required information,data and structural graphics can be inquired interactively from Aeroengine Information Database and Structure Database.

该系统可以实现对涡喷、涡扇、涡轴和涡桨航空发动机部件图和总图的参数化实时设计，在参数化设计过程中提供发动机信息数据库、结构数据库的交互式查询，为设计提供所需的信息、数据和结构图形支持，可达到快速地生成供方案论证应用的各种航空发动机部件图、总图及各种信息，能快速实现多方案对比设计。

The largest limitation in traditional data-dictionary design pattern in Information systems is short of extensibility, and it is unadapted for the acceptance of new information resources.

传统的信息模型中数据字典的构建模式存在的最大问题，就是不具备可扩展性，无法接纳新资源信息的加入。

Data mining is the process in which find information from database. The information is potential、unbeknown、valuable.

所谓数据挖掘，就是从数据库中抽取隐含的、以前未知的、具有潜在应用价值的信息的过程。

Data Mining is a worthy technology that takes potential and unbeknown information out of a huge numbers of data to guidance the practice.

数据挖掘是从大量数据中抽取出潜在的、不为人知的有用信息、模式和趋势，并用于指导实践。

Since any frequent itemset is a subset of a maximal frequent itemset (an itemset is maximal frequent if it has no superset that is frequent), this paper proposes the DMFI (Discovery of Maximal Frequent Itemsets) algorithm for mining all the maximal frequent itemsets from data sets. This algorithm searches the maximal frequent itemsets in data sets from both bottom-up and top-down directions in the meantime. This paper proposes an algorithm that evaluates the boundaries on the support and confidence of uncalculated itemsets by exploiting the information provided by the calculated itemsets.

本文在经典关联规则的基础上，提出了一系列扩展的关联规则开采算法：发现关联规则的难度体现在发现频繁项目集上，事实上最大频繁项目集（其所有的超集都为非频繁项目集的频繁项目集）的集合已经包含了所有的频繁项目集，本文提出一种发现最大频繁项目集的算法DMFI(Discovery Maximal Frequent Itemsets)，该算法采用自底向上和自顶向下相结合的搜索策略对数据空间进行有效的搜索。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
