It becomes a information exchange site,the exploration project,work area,research production,seismic datum,explainer datum,well datum can be organized into one system,which can share the research production in the exploration project;Through the datum expression of well decision,we can achieve the browsing of work area basemap,the seismic section"s remote display,the well position report"s display,the visual information of well"s wall.The system can lead to a right direction for those expert"s exploration decision .The system runs through all the process of well positon"s decision,deployment and management,which makes the exploration work becoming integrated.Now we can manage the well positon"s decision with computer,which improves work efficiency,condense whole exploration circle.

油田井位部署辅助决策系统以项目数据库的方式将分散在多个研究单位或个人手中的各类图档资料信息集中分类地保存起来，通过该系统使勘探项目、工区、研究成果、地震数据体、解释数据、井数据等有机地组织在一起，使勘探研究成果在勘探项目组内进行了充分共享；基于项目库，系统实现了井位部署决策所需的：工区底图浏览、地震剖面远程显示、井筒信息可视化，为论证专家提供了论证现场所需数据的展示；采用井位聚类分析和模糊数学综合评判决策方法，为井位论证决策提供了基本模型；利用井位部署流程子系统贯穿了井位论证、部署、管理业务的全过程中，使勘探业务有机的整合为一体，实现了井位论证工作的计算机管理。

The flood activity is one child system in this system, it also has an extremely strong nonlinearity relation with the weather system, and it is very difficult for the analysis means based on explicit function and linear measure and the mathematical model in simulating the gradual progress course and gradual progress method of flood reasonably.

水文水环境系统是一类与自然资源、生态环境和社会活动紧密相关的、极其复杂的大系统，洪水活动作为该系统的一个子系统，还与天气系统具有极强的非线性相关关系，这使得基于显函数和线性假设的分析手段与数学模型很难合理地模拟洪水的演进过程和演进规律。

Taking a SOFC–CHP system with generation scale of 70 kWe as research subject and using the design method of factorial experiment, the computer simulation experiment is carried out and the factorial analysis on part of parameters of SOFC–CHP system is conducted.

建立了系统的数学模型，以发电规模为70 kWe的系统为研究对象，运用析因试验的设计方法进行了计算机模拟试验，对系统的部分设计参数进行了析因分析。

The index system was first set up, which reflected the economy, society, resources and environment conditions in the district. Then, factorization method was employed by using the software SPSS to obtain comprehensive index numbers. The linear regression method and fuzzy mathematics method were used to compute the coordination degree of economy, society, resources and environment. Finally, on the basis of the status of comprehensive evaluation indexes and coordination degree of the district, the main problems in the sustainable development of Beibei District were found out and some suggestions were also proposed.

为将北碚建设成为国家可持续发展示范区，探讨有北碚特色的可持续发展模式，首先建立反映北碚区经济、社会和资源环境发展状况的指标体系；在此基础上，利用SPSS软件对数据进行因子分析，得到三大体系的综合评价指数；将综合评价指数代入eview软件选择适合的回归方程，再利用模糊数学的方法，计算出成立试验区以来北碚的经济、社会和资源环境的协调发展度；最后在综合评价指数和协调度的基础上，发现北碚区协调发展的主要问题并给出建议。
