Now, because the means of data administration is very poor and some other reasons, the market data approach is scarcely used by land valuator. In this paper, the author analyzes the application actuality and difficulties of the market data approach, and try to overcome these difficulties. Then the author accomplishes applied geographical information system for the market data approach based on urban land grading and evaluation system, taking Nantong city as example, and has got anticipative purpose.

Moreover, we discuss the geo spatial information value-added services network, which will be formed on the internet in the future, and the development and prospects of GIServices. The development mechanism of geo spatial information service model is summarized.

分析了每种模式的空间信息流模型与增值过程，并讨论了适合的空间信息服务应用，以及在Internet上未来会形成的空间信息增值服务网络，展望了空间信息服务的大众化发展方向。

Based on Wilcoxon rank sum test, variance ratio test and Fama-MacBeth regression method, this study finds that Chinese listed companies tend to issue new equity after information disclosure. The two regular corporate financial reports around its issuing announcement are all informative, but the one before the issuing announcement does not transfer better information to the market.

基于Wilcoxon秩和检验、方差比检验以及Fama-MacBeth回归方法的实证结果表明：我国上市公司倾向于在信息披露之后公告新股发行；我国上市公司发行公告前后两个定期报告皆具有信息含量，但发行公告之前的定期报告没有向市场传递更好的信息。

ABSTRACT: The UAV navigation system's performance is improved through embedding the geography information model that can process the vector map data in the system by using MapX, In this paper, how to navigate and plan the UAV flight course in the vector map is investigated. The basic control and operation for vector map in the geography information system is introduced, and the flight course is designed and modified in the map. In addition, 2D vector map can't orient UAV in 3D space, so the altitude model is added in the UAV navigation system to realize 3D orientation by integrating 2D vector map with altitude plot. The simulation results in the UAV simulation system indicate that the navigation system can monitor and control UAV efficiently and intuitionally.

使用MapX在无人机导航系统中添加能够处理矢量地图数据的地理信息模块，可以显著地提升系统的性能；文章对如何在矢量地图下进行无人机导航与任务规划进行了研究，完成对地理信息系统中矢量地图的基本控制和操作，并在地理信息图上进行航线的设定与修改；另外，针对二维矢量地图无法对无人机进行三维空间定位的问题，文章通过在无人机导航系统中添加高度位置显示模块，用二维平面地图与高度图相结合的方式来实现对无人机位置的三维定位；通过在无人机仿真实验系统中的使用，证明了该系统能高效、直观地对无人机飞行进行监视与控制。

Coordinate sequence method is made up of the instruct information of polygon boundary x, y coordinate. It is the easiest polygon vector encoding method. The file structure of this method is easy, but because of the polygon boundary has stored two times, it will produce data redundancy, moreover, short of neighbor threshold information; Tree index encoding method make all the boundary points digitizing, store the coordinate sequence, connect the point index to boundary line, and then connect the line index to other polygons, so as to the tree index structure has came into being. It eliminates neighbor polygons boundary data redundancy problems; Topology structure encoding method is a method which by setting up a complete topology relationship structure, resolve the neighbor threshold and island information process problem. However, it makes arithmetic more complicated and makes database bigger.

坐标序列法是由多边形边界的x，y坐标对集合及说明信息组成，是最简单的一种多边形矢量编码法，文件结构简单，但多边形边界被存储两次产生数据冗余，而且缺少邻域信息；树状索引编码法是将所有边界点进行数字化，顺序存储坐标对，由点索引与边界线号相联系，以线索引与各多边形相联系，形成树状索引结构，消除了相邻多边形边界数据冗余问题；拓扑结构编码法是通过建立一个完整的拓扑关系结构，彻底解决邻域和岛状信息处理问题的方法，但增加了算法的复杂性和数据库的大小。

It is concluded the factors of affecting information technology outsourcing decision-making into three aspects: technologic, economic, and strategic, and in-depth analyses outsourcing gaps which include technology gap, efficiency gap and strategic gap, and proposed a three-stage information technology outsourcing model, and identified technology gap, efficiency gap and strategic gap which are in the model, and in detail introduced using VENN diagram to identify technologic gap, and applied Technology Acceptance Model to perceive Information technology outsourcing.

通过对目前影响信息技术外包决策因素的相关研究进行综合分析，确定了影响信息技术外包决策的主要因素，将其归纳为技术、效益和策略三个方面，并对技术、效益和策略因素的缺口即外包缺口进行定义及分类，在此基础上，提出了一个三阶段的信息技术外包决策模型，并对该模型中的技术缺口、效益缺口和策略缺口识别方法进行了研究，其中重点探讨了基于VENN图解法的技术缺口识别方法。

Set verbosity level - 4 and above prints information on headers, 3 and above prints response codes (404, 200, etc.), 2 and above prints warnings and info.

Set verbosity level - 4 and above prints information on headers, 3 andabove prints response codes (404, 200, etc.), 2 and above printswarnings and info.

设置显示信息的详细程度- 4或更大值会显示头信息， 3或更大值可以显示响应代码(404， 200等)， 2或更大值可以显示警告和其他信息。

Also it is responsible to the security, secrecy, verity and integrity of the information.

信息安全技术是一门综合的学科，它涉及信息论、计算机科学和密码学等多方面知识，它的主要任务是研究计算机系统和通信网络内信息的保护方法以实现系统内信息的安全、保密、真实和完整。

My conclusions are these: 1 In a simple full information society, both government and market are effective on reducing the social fare loss caused by externalities. 2 In a more complicate problem of externalities, market is no more effective than government, vice verse. 3 Information is correlated to the existing of externalities, information asymmetry and uncertainty can lead to externalities.

得到的结论是：1在一个简单的信息充分的社会中，政府方式和市场方式都有效，都能降低外部性所导致的社会福利净损失。2在复杂的外部性问题上，市场方式并不一定比政府方式优越，反之亦然。3外部性的产生与信息有关，信息不对称与不确定性可以诱发外部性。
