Garbagemail is a global problem. So, the trash mail server of every E-mail server has an anti-trash system. And Shangyi also does. Anti-trash system works automaticaly, but not controlled by people. So, the system sometimes makes mistake. And it would send feedback to senders and receivers while mistake happens as: Respond:450 Requested action not taken\. In that case, in order not to affect you to send and get your mail, we suggest the management of the other side to shorten the system for resending list. We will also update our anti-trash system time by time so that it would work properly.

垃圾邮件是一个全球性的问题，所以每个邮件服务商的邮件服务器都会有反垃圾过滤系统，而尚易也是如此，反垃圾系统也不是人为的操作将邮件判为垃圾邮件或正常邮件，而是系统自动判别，所以也会出现误判的现象，当出现这种情况会给对方服务器反馈信息，Respond：450 Requested action not taken\，所以也建议对方的管理员将服务器设置中再次投递的队列机制的间隔改的短一点，这样就不会影响您邮件的收发了，我们也会将反垃圾系统不断更新，而使正常的邮件的投递率会更高。

Since the voltage not only has relationship with both the reactive power and the balance of reactive load, but also relies on the structure of network and capability of voltage regulation, the system takes all the factors above into consideration and adopts the methods as follows: realizing grading control and management according to the voltage level and region partition, realizing jointly regulation and information pool by the application of advanced software in local and central station, realizing the optimal control of reactive voltage based on the measurement data from the regulative automation system and the angle of the whole system, realizing the exact application of reactive compensator and the on-load tap appropriate changer for voltage regulation transformers , and realizing the balance of reactive voltage in local site.

随着调度自动化系统的日益普及，以及越来越多的电网中的有载调压分接开关和电容器补偿装置投入使用，本课题研究开发基于分级递阶的地调/中心站模式无功电压控制系统，由于电压既与无功功率和无功负荷平衡有关，又与电网结构、调压能力有关，所以系统考虑电压等级、按区域实施分级控制、分级管理，利用中心站和地调的电力系统高级应用软件的作用实现众多装置的联合调整，信息共享。

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。
