Through detailed analysis of the concept and nature of the "megalopolis", this paper discusses the relationship and influence factors between change of the industrial and urban and township spatial structures of the Yangtze Delta Area and argues that: i the two highly modernized networks (infrastructure networks and the market and industrial organization networks) based on functional division of labor between individual cities possess crucial importance in facilitating change and upgrade of the industrial structure on one side and sustained optimization of the organizational pattern of the urban and township spatial structure on the other; ii in the light of the Yangtze Delta Area, influence factors in promoting positive corresponding states between change of the industrial structure and urban and township spatial structure are concerned with development level of the first place city, rational and orderly hierarchy of the urban and township system and, meanwhile, up-to-dateness of the city networks.

本文以长三角为研究地区，对产业结构演进与城镇空间结构的对应关系和影响要素进行了探讨。据此认为，基于城市功能定位和合理分工基础之上的高度现代化的两大网络（基础设施网络、市场体系和产业组织网络）是推进产业结构不断演进和升级的重要条件，也是推动城镇空间结构和组织模式持续优化的着力点和主要抓手；促进产业结构演进与城镇空间结构对应的影响要素主要包括：首位城市的发达程度、城市间合理和有序的层级关系、城市体系网络的现代化程度。

Finally, stochastic vibration analysis of a two-floor frame structure by blasting seismic action is done by finite element program ANSYS. In order to contrast, that by nature seismic action is also done here, and displacement field, velocity field and stress field of this two kind of condition are obtained, and differences of the structure damage mechanics by two kind of action are analyzed. Dynamic reliability analysis of the two-floor frame structure is done using of simulation results, obtaining the safe reliability level of the structure by seismic action, and seismic safety evaluation of the frame is completed.

最后，运用有限元程序ANSYS对爆破地震动作用下一个两层框架结构进行了随机振动分析，为了进行对比，这里也对结构受天然地震动作用进行了随机振动分析，得到了两种地震动作用下结构响应的位移场、速度场和应力场的变化情况，分析了爆破地震动和天然地震动对建筑结构物破坏机理的不同；应用数值模拟的结果对该两层框架结构进行了动力可靠性分析，得到了其在地震动作用下的安全可靠度，完成对该框架的爆破地震安全性评估。

From ORACLE system structure, the paper organizes and allocates memory with SGA and PGA. The key of performance tuning is to confirm the hit ratio of system. The ORACLE system's store structure includes physicial structure and logical structure. So , it is the basis to decide the size of tablespace, data file and control file. The database object includes index, cluster, views and store procedure etc., the object have important effect on database. Lastly, it contrasts the ways of Based on Cost and Based on Rule and organizes the SQL under SQL/PLUS system environment.

本文从目前的医院信息系统现状分析，提出系统性能评价指标，并从ORACLE体系结构出发，对内存区中的系统全局区及程序全局区进行合理的组织与分配，确定合理的命中率，这是性能优化的关键；ORACLE存储结构采用的互为关系的逻辑存储结构与物理存储结构，故确定其中的表空间、数据文件、控制文件的大小是性能优化的基础；数据库对象结构中的索引、簇、视图、存储过程等对其进行合理的设计，对大型数据库的性能有着重要的影响；最后便是在SQL／PLUS境下，通过与基于代价与基于规则的方法进行比较，对合理高效的SQL语句进行组织，并列出优化后系统性能的情况。

Finally, the locations of independent buildings were obtained. In the aspect of structure line detection, the main idea is to separate the roof structure lines into two parts, one is for external contours and the other is for internal structure lines. The external contours were extracted using Hough transform and other geometric conditions. The internal structure lines were extracted by any two adjacent roof faces intersecting each other.

而在结构线的侦测方面，主要将屋顶结构线分为两个部份来进行，第ㄧ为外部轮廓线，萃取的方式是利用霍夫转换及其他附加几何条件来进行；第二为内部结构线，萃取的方式为利用相邻屋顶面的交会来获得；最后再将此二种特徵线合并在一起，进而重建完整的屋顶面形状。
