文回顾与评述了三维GIS的相关发展情况，探讨了三维GIS的有关基本问题，如数据获取、大数据量存贮与处理、三维空间分析，同时指出科学计算可视化、数据库系统管理、数字影象处理等技术的成熟和二维GIS长期发展提供的理论实践经验等为三维GIS的发展提供了良好的基础。最后为三维GIS实际系统的开发提出了几个值得注意的要点。-In this paper,the review and comment on the development of 3 dimension GIS are first made.Then the basic aspects about 3D GIS,such as data acquisition,storing and processing of mass data,analysis of 3D space,are discussed.Meanwhile, it points out that the techniques such as scientific computation visualization,database system management and digital image processing,and theories and experiences provided by development of 2D GIS offer a better platform form the development of 3D GIS.Finaally,some key points in developing practical system of 3D GIS is proposed.

要求随机关生一个序列，任意查找其中一个元素时，采用二分搜索法实现，并且还能显示查找次数。使用二分法首先要使序列列按从小到大排序，因此程序中还要有排序功能。- there is a random series ,when looking for any an element in this series,we can achieve this by the method of bisectional searching,also the number of search times will be displayed.when using this method ,first of all you should sequence the series bigger and bigger.For this reason the program shoule have the founction of secquencing.
