This paper has an overall research on the theory and methods of GIS integration combining Xi'an international airdrome infrastructure management information system, air pollution simulating system and 3S integration prototype system.

本文以西安咸阳国际机场基础设施管理信息系统、大气污染模拟系统、以及3S集成原型系统的建立与开发为例，对地理信息系统集成的理论和方法进行了比较全面的研究。

From a practicable point of view, models in MBMS were further classified into three types: Mathematical Equation Model, Conditional Model, and Image Processing Model.

本文着重研究基于地理信息系统的模型库管理系统，试图通过建立模型库管理系统的方法弥补地理信息系统在模型分析方面的不足。

As a type of complicated information system, E-government system is usually made up of many subsystems which be dealt by different security strategies, be distributed in geography, belong to different departments, their systemic users can be active in many systems in the same time. There are great capacity resource and user info in each subsystems. Therefore, E-government system is faced with validity, utility, dynamics, distributivity, real-time nature and compatibility etc. challenges in access control technology aspect.

电子政务系统作为一类复杂的信息系统，通常由多个应用着不同的安全策略、地理上分布的、分属不同部门的、多用户同时在线的子系统组成，各系统内部存在越来越多的海量资源和用户信息，因此电子政务系统在访问控制技术方面面临着有效性、应用性、动态性、分布性、实时性、兼容性等严峻挑战。

In particular the reasoning efficiency and precision of the expert system are improved further through self-learning the thresholds of monitoring parameters.

专家系统与一般的信息管理系统的区别不仅在于知识从流程中的分离(知识和知识使用是分离的)，更在于这些知识主要是经验知识，因此获取知识困难，开发专家系统要比一般的信息管理系统更复杂。

College Teacher Management Information System is a typical information management system. The basic information management and the query system is one of the foundation part of the whole system.The procedure's development includes the establishing and maintenance of backstage database and the forepart application two aspects.

The major contributions of this thesis include:(1) proposing a new kind of optimal feedback control, followed by its application to chaos targeting and stabilization of high period unstable periodic orbits ;(2) stabilization of unstable fixed point in chaotic systems using some kind of nonlinear feedback control, and giving sufficient condition for the existence of the controller as well as the synthesis procedure;(3) analyzing the robustness of optimal control in chaotic Lur'e systems under the help of H〓 control theory;(4) finally and most importantly, introducing a novel method of information storage based on discrete time chaotic systems as the application of chaos control, and systematically studying different schemata for implementation, providing a theoretic basis for the design of such new kind of information storage devices with large capacity.

本文的主要工作包括，提出一种新的最优反馈控制，并将之应用于混沌引导控制及混沌系统高周期不稳定周期轨道的镇定控制；针对不动点镇定控制的一类非线性反馈控制器，文中给出该类反馈控制存在的充分条件及设计步骤；文中还利用非线性H〓鲁棒控制理论对Lur'e混沌系统中的最优线性反馈控制进行鲁棒性分析；最后，也是最重要的，作为混沌控制的应用，文中提出一种基于离散时间混沌系统的信息存储方法，系统地分析、研究了实现这种信息存储的不同方案，为以后进行这种新型大容量存储器设计提供了一定的理论依据。

Construction of informatization of Bao inn colliery has mining industry of innovation Yan state colliery of company Bao inn builds production to manage attemper after the management information system, simplified the passageway that information delivers, assured the seasonable sex that information is delivered and offers, avoided to decrease to machine the repetition between the information in the process with; of lack fidelity phenomenon mussily, avoid the contradiction between all sorts of information, queue up or be out of line phenomenon, be helpful for making sure the useful sex of information and accuracy; raised the utilization rate of information.
