The results indicated that most students were dependent on the problem's surface structure for their sortings. Futhermore, an interaction effect was found between the student's grade and their achievement. As the grade level increase, instesad of using surface structure, high achievement students tended to sort problems according to their semantic structure. On the contrary, low achievement students became relied more and more on the surface structure of the problems while sorting.

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。
