This paper is based upon XiShan Colliery Parent Company .The data of DongQu Mine pit ventilation resistance mensuration is combined. And system theory, graph theory, ventilation network technology and computer technology are utilized. According to the reality of coalmine, we think that graph and database is incorporate in mine ventilation system. So based on this, ventilation system standard graph is founded, the tool of ventilation graph to draw is made, the ventilation network calculation is realized, the outcome of the ventilation network calculation is seen on the screen, and opaquing and inquiring of the road parameters and so on. In addition to mine ventilation drawing-database visual management system is developed.

本文基于西山煤矿总公司东曲矿〖东曲矿矿井通风网络计算机管理系统〗科研项目，结合东曲矿矿井通风阻力测定，运用系统理论、图论、通风网络技术及计算机技术，针对煤矿实际，将矿井通风系统中图形和数据库贯穿为一体，创建了通风系统标准图库并编制了通风图形绘制工具，实现了风网解算和解算结果图形显示及巷道参数的修改、查询等功能，开发了矿井通风图形数据可视化管理系统。

Moreover, A hybrid algorithm, ALHybrid, which is made of the algorithm LIDBSO and the algorithm AprioriIpv, is designed. Two algorithm, MQC_Apriori and MQC_LIDBSO, are given to mining multiple level quantitative association rules with item constrains. Two algorithm, PMARⅡ and PMARⅢ, which are based on different sequential mining algorithms, are given for parallelling mining association rules. In order to solve the mining association rules problem when we add a set of data to a database or delete a set of data from a database, two incremental updating algorithm, EUAR and EUAR, are given. Three incremental updating algorithm for association rules mining, DIUAⅠ, DIUAⅡ and DIUAⅢ, are dedigned to solve the three kinds of association rules incremental updating problem in distributed databases.

另外，文中还设计了一个算法LIDBSO与算法AprioriIpv相结合的混合采掘算法ALHybrid；对于多层次、带约束、多值属性关联规则的采掘问题，给出了两个采掘算法：算法MQC_Apriori和算法MQC_LIDBSO；在关联规则的并行采掘方面，还设计了两个基于不同顺序关联规则采掘算法的并行算法：算法PMARⅡ和算法PMARⅢ；在关联规则的增量式更新问题上，还给出了两个改进算法：算法EUAR和算法EUARˉ，分别用于解决当数据库增加或删除一个数据集合时的关联规则增量式更新问题；针对分布式数据库中的关联规则增量式更新的三类问题，提出了三个增量式更新算法：算法DIUA Ⅰ、算法DIUAⅡ和算法DIUAⅢ。

According to the GOC needing and the project of GD technology, this project is Base on GoC's SO2 production equipment and launched by GD University. The user of this system is GOC.Intelligent diagnosis technology is the integration of neural network technology, expert system technology and database technology, which is the result of development of science and technology. Making full use of it can diagnose faults effectively, guarantee the normal work and increase the productivity. It can also prevent the blindness of diagnosis and make the managements more normative. It has significant benefit on environment pollution diagnosis. In this paper, this Database system is summered and prospected.

本项目是根据广州石化安环部提出的：&广州石化重点污染源监测数据采集、分析与控制系统&建设需求及2002年广东省科技计划项目：&制造业企业环境管理体系建立与运行控制的关键技术研究&建立的；项目的开发方为广东工业大学，系统的用户为广州石化安环部，以广州石化年制硫量2万吨装置为研究对象，研究出一套通用的污染因素分析方法，在此分析方法之上，开发出一套基于数据库的污染源智能诊断专家系统，当出现污染物超标时，能根据各种工艺参数，快速、自动的推断出污染源的位置，从而可以采取相应的措施，控制污染物的排放，减少污染物的排放量与降低污染物的排放浓度，使得企业在满足环保要求的情况下连续有序的生产。
