Firstly it describes the development ,basic principle and application and propagation characteristic of mobile channel , then investigates the system structure of DAB transmitter and receiver separately and the key technology of realization of the digital audio broadcast system.And then discusses the system component of FFT －the demodulation module of OFDM .The 409- points FFT module employs a radix-4 decimation-in-frequency algorithm, includes arithmetic element , read and write address element ,twiddle factor element and control element , is realized by FPGA. In the end , the result is verified in the matlab .

首先概述了OFDM的发展、基本原理和应用以及移动信道的传播特性，接着分别研究了数字音频广播接收机和发射机的系统结构，以及数字音频广播系统实现的关键技术，然后详细论述了OFDM解调模块FFT的系统结构，主要研究了4096点FFT采用基－4按频率抽取实现的算法，整个FFT模块包括了运算单元、读写地址单元、旋转因子单元以及控制单元，并且在FPGA中进行了硬件实现，并在matlab环境下对结果进行了验证。

We compare the clinical symptoms,physical sign fading time ,the Balthazar grade of CT examination after treatment for three days and by statistic methods.

目的 研究静脉使用甘露醇辅助治疗急性胰腺炎的临床疗效方法对经保守治疗好转的急性胰腺炎病例进行回顾性分析，从中随机抽取40例辅助使用甘露醇的病例和40例未使用的病例分成两组，通过对比使用组与未使用组临床症状、体征缓解的时间及治疗3天后CT检查的Balthazar评分，并进行统计学处理。

First design a reasonable XML Schema structure and under the restriction of XML Schema use XML to describe the UML class diagram and the related specification, and then extract the test specification of method from XML test script. Test specification refers to predicate sequences in the form of conjunctive normal form, extracted from basic constraint conditions of variables included in test scripts and expected outputs. Each conjunctive normal form can be transformed to an inequation set, and adopt 1×1 domain test strategy to every inequation set to produce the domain test matrix, which in turn produce the test case.

首先设计合理的XML Schema结构，并在该XML Schema的有效性约束下，用XML对UML类图及相关性约束进行脚本描述；其次对XML测试脚本进行分析，提取方法的测试规约说明，所谓测试规约说明就是从测试脚本中包含的变量的基本约束条件以及期望输出中抽取得到的以合取范式形式存在的谓词序列；每一合取范式对应一个不等式组，对每一个不等式组采用1×1域测试策略，生成域测试矩阵，最终得到测试用例。

Data mining is a process of learning and gaining connotative and valuable information.

数据挖掘是从大规模的数据中抽取非平凡的、隐含的、未知的、有潜在使用价值的信息的过程。

The applications of the theory in robot translation parameter computation and in Qualitative Scene Model construction are presented.(3) Intrinsic Images and color constancy of Real Color Images Based on the Dichromatic Reflection Model proposed by Klinker [55] , it is the NO. 1 for this paper to measure the spectral relationship of a CCD color camera, to reestablish the linear relationship, to separate the illuminant and object color components in real color images, and to extract the intrinsic image and highlight image from the real color image, as well as to eliminate the influences of highlights upon the usual image segmentation algorithm.

以Klinker[55]等提出的"双色反射模型"为基础，首次测定了彩色摄像机的光强----灰度响应关系，恢复了摄像机的整体线性关系；首次在真实彩色图像（即由彩色摄像机直接获取的图像）中成功地分离了光照和景物的颜色；成功地抽取了本色图像和耀斑图像；在此基础上，又将双色反射模型成功地运用到真实彩色图像的分割方面，消除了耀斑对分割的影响。

Perpendicular search engine is to pour pyramid model, be pair of trade news comb, rework and editor are arranged, it is the professional search engine that is aimed at certain industry, the fractionize that is search engine and outspread, it is right some kind of technical information in webpage library undertakes conformity, directional cent field is draw-out the user is returned with some kind of form again after the data that gives need undertakes handling.

垂直搜索引擎是倒金字塔型，是对行业信息的梳理、再加工与编辑整理，是针对某一个行业的专业搜索引擎，是搜索引擎的细分和延伸，是对网页库中的某类专门的信息进行一次整合，定向分字段抽取出需要的数据进行处理后再以某种形式返回给用户。

With the analysis of the features of tree system,potential aspects which could influence tree classification results are studied,the factors that should be taken into consideration in modelling hibernal tree classification are proposed and are concluded to six main aspects of features,amongst them the most correlated contents and information for classification are picked up to set up hibernal trees classification model,and finally implements the classification model with Bayes,which accomplishes a hibernal tree classification system based on Bayes.

通过分析树木体系的特征，研究并分析了可能影响树木分类结果的几个方面，提出了树木分类建模时应该考虑的因素，并将其归纳为六个方面，从中抽取与分类最相关的内容和信息，构建了冬态树木分类的模型，最后用贝叶斯方法实现了该分类模型，完成了基于贝叶斯的冬态树木分类系统。

Through these research, we have two main conclusions:CRM is the effective method of enterprises management the customers, and the data mining is the powerful tool of derived latten and value knowledge from mass data, and the effective union of them may provide the powerful support for the telecom company 's scientific policy-making and enhance the core competitive power of telecom company

通过实证分析，得出了两个主要结论：(1)CRM是电信企业进行客户管理的有效手段，数据挖掘则是可以从大量数据中抽取出潜在的、有价值信息和知识的强有力的工具。两者有效的结合可以为电信企业经营、科学决策提供有力支持，从而提高电信企业的核心竞争力。

In order to overcome the incompleteness of the data types as well as keep the problem overdetermined, a challenging work on efficiently extracting new data types from measured TPSFs has been under its way. One of the solutions to this work is solve the problem in its frequency domain-which introduce the GPST.

为克服数据类型的不完备性以及保持问题的超定性，快速而有效的数据类型的抽取一直是光学CT研究中的重要课题，解决办法之一是将问题变换到频域进行求解-这便是GPST的基本思想。

Can join a web page platformer, for example my QQ space station, then increase a game channel on own website, do some publicity, guide the customer plays games, when the customer indulges in among them of time, will self-movingly deliver to stick a discussion on the website, exchanges game insight etc., even the customer is in the game at the time that Chong was worth, the station-master canned also sample considerable lift.

可以加入一个网页游戏平台，比如我的QQ空间站，然后在自己的网站上增加一个游戏频道，做些宣传，引导用户去玩游戏，当用户沉溺于其中的时候，就会自发的在网站上发贴讨论，交流游戏心得等等，甚至用户在游戏中充值的时候，站长还可以抽取相当可观的提成。
