南通市现辖四市（如皋市、通州市、海门市、启东市）两县三区（崇川区、港闸区、南通经济技术开发区），全市总人口784万，耕地面积465.67千公顷，种植业有粮食、棉花、油料、林业、果树、花卉、蔬菜、蚕桑等种类，尤以如皋盆景、银杏、&四色豆&、速冻蔬菜、加工蔬菜等出口而闻名；畜禽养殖业特别发达，种类有三元瘦肉型猪、海门山羊、如皋黄鸡、狼山鸡、AA肉鸡、新罗曼蛋鸡、乳牛、欧洲肉鸽、野鸡、野鸭、驼鸟等。

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。

The comprehensive heat transfer basic trial study about the influence factors, regular pattern and the limit heat transfer capability and effect of augmentation of heat transfer of jet impingement has been completed.

在关于发生在磨削弧区的传热过程的深入的机理研究的基础上，提出了可以通过有效强化弧区换热过程，大幅度开发高效磨削潜力的创新思想，并在此基础上构思设计了采用径向高压水射流冲击强化冷却弧区工件表面的独创方案。

The invention provides a touch input method and a portable terminating set. The touch input method which is applicable to the portable terminating set comprises the following steps that: a touch instruction is received; the touch instruction is calculated in a range to get a press area; a cursor is generated according to the touch instruction; the cursor is arranged selectively in a preset range on the periphery of the press area according to the current position of the press area.

本发明是有关于一种触控输入方法及可携式终端装置，该触控输入方法是应用于一可携式终端装置，包括接收一触碰指令；对触碰指令作一范围演算，并得到一按压区；根据触碰指令产生一游标；以及根据按压区的一目前位置选择性地将游标配置于按压区外围的一预设范围内。

Fdisk is not only a zoning process, it has a very convenient feature to restore the main boot sector, but only modify the main boot sector, other sectors of the write operation is not carried out, so for those who are still using Windows 9x friend the case of no doubt is a very good tool to repair the partition table.

Fdisk 不仅是一个分区程序，它还有着非常便捷的恢复主引导扇区功能，而且它只修改主引导扇区，对其他扇区并不进行写操作，因此对于那些还在使用 Windows 9x 的朋友而言无疑是个非常理想的分区表修复工具。
