Through simulation and computation, some critical values to contral interferences are obtained. These values have directive significance to the design and deployment of WRAN.(4) New methods to measure and analyze spectrum aredevelopedAccording to the shortages of previous spectrum measurements, new methods to measure spectrum occupancy in wide-band and multi-point synchronously is proposed in this dissertation, and the tests last a whole week; the relativities of licensed services are considered when test points are selected. More importantly, data mining and in-depth analysis are carried out with the huge amounts of test data, and a channel analysis method using Channel Vacancy Duration and Service Congestion Rate are proposed. The spectrum relativities of 3-dimension in time, space and frequency are researched also. The correlativity between channel state and history information is discoved, and which will provide the scientific basis to channel modeling, spectrum analysis and decision of CR users.

4提出了频谱测量与分析的新方法针对以前频谱测量工作存在的不足，本文提出了多点同时广域频谱测量方法，测量工作持续了一周的时间，同时考虑了测量地点的选取和频谱授权业务之间的相关性；对测量得到的海量数据进行了数据挖掘和深度分析，提出了使用信道空闲时间(Channel VacancyDuration，CVD)和业务拥塞率(Service Congestion Rate，SCR)进行信道分析的方法，研究了频谱之间的时间、空间、和频率三维立体的相关性，发现了信道状态和历史信息的关联性，为CR用户的信道建模、频谱分析和决策提供了科学的理论依据。

In order to meet the communication model requirements of hospital information standardization, the communication part of DICOM standard and the data structure have been analyzed detailedly. The DUL states-machine, DUL layer, and DIMSE service are designed. The DICOM interface in the workstation has been implemented to transfer ECG DICOM files.

This method has more practical value. First, this article has introduced the research situation of real-time transportation information collection, including the taxi electronic dispatch system as well as the corresponding technology. Analyzed the mothod of map coordinates transformation and the match method of vehicles localization data, then has analyzed the vehicles localization effective sampling with emphasis according to the drivers driving custom to get the tavel time of the road sections. It has filled the transportation blank region data.With the experiments of real data, explained this algorithm could obtain the road section reasonable travel time, int could describe the road network real-time condition.

本文首先介绍了实时交通信息采集的研究情况，包括电召系统以及相应的技术，分析了地图坐标转换、车辆定位数据匹配方法，然后根据驾驶员行车习惯重点分析了车辆定位有效采样对的获取并在此基础上进行单车路径旅行时间求取、时段内旅行时间求取的算法，填补了交通空白地带数据，并通过路上试验，说明该算法能够得到路段合理的旅行时间，能够描述路网的实时状态。

However, post-production measurements record pressure changes over a short time frame and this can reveal important field-scale compartmentalisation information that was not apparent from the virgin dataset.

然而，后期生产的测量却记录了短期内的压力变化。这揭露重要的油田规模分区信息，从原始数据集中是不能轻易获得这些信息的。

Based on the properties of hyperspectral image data, effective classification algorithms for extracting most information of groundcover types from hyperspectral image data are studied in this thesis.

本文针对高光谱图像数据的特性，研究了如何从高光谱数据中提取出地物类型的丰富信息以进行有效的分类。

The DTM for automatic-design of thruway was put forward by Prof. Miller in 1956. Since then , the DEM is used for design of various circuit diagram, and for account of area, cubage, gradient of various project, and for estimating visibility from point to point; for rendering contour, grade-graph, aspect-graph, solid model; for making orthographic image and repair map in the Topography; for assistant data to classify in the Remote Sensing; as basic data in the GIS, for analysis and layout actuality of using soil, for disaster prediction; for navigation, guiding missile in the military affairs.

美国麻省理工学院Miller教授为了高速公路的自动设计于1956年提出了数字地面模型的概念后，DEM被用于各种线路的设计及各种工程的面积、体积、坡度的计算，任意两点间可视性判断及绘制任意断面图；在测绘中被用于绘制等高线、坡度坡向图、立体透视图，制作正射影像图与地图的修测；在遥感中可作为分类的辅助数据；它是地理信息系统的基础数据，可用于土地利用现状的分析、合理规划及洪水险情预报等；在军事上可用于导航及导弹制导；在工业上可利用数字表面模型DSM或数字物体模型绘制出表面结构复杂的物体的形状[2]。

ISO 10303, is issued by international standardization organization, and here, this paper gives the definition of product structure model oriented part41 and part44 in STEP and content of product structure management in PDM.
