The thesis studies the difference between GWSs composition and traditional workflow applications, proposes the implement mechanism and technical architecture of GWSs composition and defines the reference model of GWSs composition platform, which provide holistic framework and top-level guidance for studying dynamic GWSs composition technology, designing GWSs composition platform, and implementing representative composite service applications.2、Theories and methods of composite process modeling and process analysis. This thesis proposes a meta-model of Geo-spatial Web services composition process defining from two aspects, i.e. process and resource. According to the process definition meta-model, we propose a new Geo-spatial Web services composition Process/Resource model based on extended WF-net, which effectively resolves the problems on uncertain activity option and dynamic variation of service in composite process model. A notion with regard to soundness of process model is proposed from three aspects, i.e. the structural correctness of process model, validity of data link and validity of resource. The notion of soundness definitely gives a dividing line on correctness of composite GWS process. This thesis analyzes sufficient and essential terms of soundness, and studies compositional property of WSCP/R-net models which provides an effective method to construct a soundness WSCP/R-net model. According to WSCP/R-net, the thesis proposes composition algebra and studies the properties of it. Based on the composition algebra, 6 kinds of composite process reduction rules are induced to optimize the process.3、Geo-spatial Web service QoS model and its application architecture. This thesis proposes an extendable GWS QoS model from three aspects, i.e. Geo-spatial Web Service itself, networking conditions and service consumer which can be used to distinguish GWSs with overlapping or identical functionality. We work over the QoS evaluation methods of composite GWS process which can be used to guide the execution, monitor and service selection of composition process. Aming at some disadvantages in traditional Web service discovery model for its lacking of QoS supporting, this thesis proposes a new service discovery model SDMQ supporting QoS constraints.4、Technologies of composite service executing. SSPL, a new composite service process language, is defined to overcome the disadvantages of existing composite services process languages which can not adapt to the dynamic variation of Geo-spatial Web Services. An algorithm is described to translate WSCP/R-net model into SSPL. The thesis studies the model of dynamic services selection with QoS global optimization, presenting an algorithm GODSS to resolve dynamic services selection with QoS global optimization in GWSs Composition.5、Design and implement experimental system and representative applications. According to the research findings presented above, we design and implement an experimental system and construct two representative applications to show that our achievements are effective and practical.

Comparing withHayek's theory on society method, I believe constitution litigationmechanism must considering the following conclusion in modelingconstitutional method: first, the acquiring of constitutional method isusually effects system vicissitudes. Although constitutional arbitramentcan form definite constitutional method, it can't achieve perduringsubstantial results level of method; secondly, constitutional method isformed virtually by the mixture of two kind of potence, and one is socialpotence, the other is governmental potence. The constitutional method'srationality in logic structure rests directly with the wrestling process ofconstitutional logic and social process. Constitutional method is more akind of simulative conformation of natural logic and social logic, itforms by the wrestling of government, public, legislature andconstitution judging organ. Fourthly, the maintenance of constitutionalmethod depends on the inner power sustained by faith and exteriorpower coming from the background of compulsion. Fifthly,constitutional method itself is a dynamic structure, and it's realizingquomodo and vindicating means is being in vicissitude, however, it canonly provide condition and inspiritment.

对照哈耶克的社会秩序理论，笔者认为，宪法诉讼机制在型构宪政秩序时必然要照顾到以下结论：其一，宪政秩序的取得，往往是一个制度自然变迁的结果，宪法裁决虽然也可能在短期内形成一定的宪法秩序，不过却无法强行地达到一个较大范围内持久的秩序实效水准；其二，宪政秩序实际上是由两种力量交合而成的，一是社会力量，一是政府力量，宪政秩序的逻辑结构的合理性直接取决于宪法逻辑和社会逻辑之间的博弈过程；其三，宪政秩序更多的是一种对自然逻辑和社会逻辑的模拟形态，是经由政府、公众、立法机关与宪法裁判机构的合作博弈而形成的，宪法诉讼的功用至多在于提供博弈规则，以实现纳什均衡；其四，宪政秩序的维护主要依靠来自信念支持的内部力量与来自强制背景的外部力量；其五，宪政秩序本身是一个动态的、常新的结构，其实现方式与维护手段也处于不断变迁之中，但无论如何，宪法诉讼机制所能提供的只是制约与激励两种。
