Viii Furthermore, topicalisation realises the situational parameter Mode, the speaker's manipulative ways of arrangements of experiential meaning in terms of his cognitive schema and communicative intention in aware of the addressee's knowledge; and the phonological category for realising Theme and Topic is Tonicity. It is then clear that topic systems in text are informational in essence.

After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.

具体研究工作及成果如下：（1）根据点集拓扑理论中与拓扑空间相关的概念，本文对空间的点、线、面进行了重新定义，以区分对象的复杂性；分析了9I模型在表示简单对象方面的优点，以及在表达复杂对象上的不足，阐述了本文的研究思路和解决方案，并以复杂的面面、线线和线面为例详细探讨了复合拓扑关系的表达方法；（2）分析了地籍权属数据和地类数据的内涵、特点和要素之间的联系，根据复杂对象的拓扑关系表达模型，本文讨论了宗地、界址线、界址点之间，图斑、线状地物、零星地类之间可能存在的拓扑关系和形式化表达方法，归纳总结了地籍对象的拓扑关系满足的约束性规则；（3）将拓扑关系的研究延伸到时空领域，从地籍对象的时态性出发，本文阐述了地籍数据中时间的含义和变化语义描述的需要；从时间、位置、状态、事件等之间的拓扑关系方面，重新系统性地进行了时空拓扑关系的定义；研究了一维时间和二维空间的集成表达方式，以宗地、界址线为例，分析了变更前后不同时间区间里可能的拓扑关系，探讨了时空拓扑关系对时空变化操作类型和变化语义的推理方法和意义；（4）为实现空间拓扑关系的查询分析等应用，本文研究了空间拓扑关系的计算方法。

In order to improve the existing generic service oriented intrusion tolerant system in aspect of architecture and function, this paper presents an improved adaptive intrusion tolerant system with improved architecture, functional modules and key techniques. From an overall consideration of the system, mixed with firewall, intrusion detection and other traditional technologies, IAITS combines redundancy, diversity and various fault tolerant techniques, thus enhancing reliability through active replication and secure multicast, reaching tradeoff between system complexity and intrusion tolerance ability by redundant design only in most vulnerable components, and supporting data protection on the basis of architecture with only a little extra cost in software and hardware by making use of topological coherence between application servers group and key share servers group.

本文针对目前面向通用服务的容忍入侵系统在架构和功能上的不足，提出了一种改进的自适应容忍入侵系统，在系统结构、功能模块以及关键技术上做出了改进的设计：从整体上考虑系统结构，将防火墙、入侵检测等传统的安全技术融合到容忍入侵系统的设计中；综合了以冗余与多样性为主的多种容错技术，采用主动复制与安全多播，增强了系统的可靠性；仅在最易受攻击的部件上采用冗余设计，兼顾系统复杂性与容侵能力；利用应用服务器组和密钥服务器组在拓扑结构上的一致性，在基本不增加软硬件开销的情况下，从架构上支持数据保护的功能。
