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.

针对当前空间信息服务聚合研究中存在的若干不足，本文重点在基于工作流的空间信息服务聚合框架、空间信息服务聚合流程建模和分析技术、空间信息服务QoS模型及应用体系以及空间信息服务聚合流程执行等几个方面进行深入研究，主要工作和创新点包括：1、基于工作流的空间信息服务动态聚合框架：研究了空间信息服务动态聚合和传统工作流应用的不同，在此基础上提出了基于工作流技术的空间信息服务动态聚合实现机制、技术体系和参考模型，为研究空间信息服务聚合的关键技术、开发服务聚合支撑平台以及在此基础上构造特定的空间信息服务聚合应用提供了总体框架和顶层指导。2、空间信息服务聚合流程建模和分析技术：首先基于动态服务聚合流程建模的需求和空间信息服务动态变化的应用实际，从服务聚合的过程维和资源维出发定义了服务聚合流程定义元模型；与之相对应，对基本的WF-net进行扩展，提出服务聚合流程/资源网作为空间信息服务聚合流程的形式化描述模型，有效解决了现有的基于基本Petri网和工作流网的服务聚合建模方法所不能解决的不确定路径选择和服务的动态变化性问题；从流程结构正确性、数据依赖有效性和资源实现有效性三个方面提出了WSCP/R-net健壮性的概念，明确界定了聚合流程正确性的标准，并对WSCP/R-net模型的健壮性分析方法和WSCP/R-net模型的组合特性进行了研究；提出了空间信息服务聚合代数算子并对其性质进行了研究，在此基础上提出了6种聚合流程约简规则，从而可达到优化聚合流程、提高聚合流程执行效率的目的。3、空间信息服务QoS模型和应用体系：从服务本身、网络环境和服务消费者三个层次出发，提出了一个可扩展的空间信息服务QoS模型GSQM，实现了对空间信息服务的度量和评价，并对GSQM不同质量要素信息的客观、公正采集方法进行了研究；研究了空间信息服务聚合流程QoS评价方法，有效支持了空间信息服务聚合流程的执行、监控以及服务选择等操作；针对目前的服务发现模型仅支持服务功能性描述、不能有效满足空间信息服务应用需求的现状，提出了一种新的支持QoS约束的服务发现模型SDMQ，并对模型的实现框架进行了研究。4、空间信息服务聚合流程执行技术：针对现有的服务聚合流程描述语言不能有效满足空间信息服务动态聚合流程描述的特点，基于BPEL4WS提出了一种新的空间信息服务聚合流程描述语言SSPL；研究了满足健壮性要求的WSCP/R-net模型向SSPL的转换算法，在此基础上可以满足用户无显式编码来实现空间信息服务聚合应用的目的；研究了服务动态选择QoS全局优化模型，并在此基础上提出了一种解决服务动态选择QoS全局优化问题的实现算法GODSS.5、基于论文研究成果，设计实现了"空间信息服务聚合实验系统"，并构建了"矿产资源评价"和"城市消防应急响应"两个典型应用案例，对论文所述模型、方法的可行性和有效性进行了验证。

But under the laws of Germany this could not be done without the concurrence of the princes; and, overcome at last by the legate's importunity, Charles bade him present his case to the Diet.

但根据德国的律法，这件事情若得不到诸侯的同意是不能执行的；结果，皇帝终于因亚利安德的恳求不已而让他向议会陈述他的意见。

The necessity for such government arises from the failure or inability of the legitimate government to exercise its functions on account of the military occupation, or the undesirability of allowing it to do so.

If any provision of this Agreement is held invalid or unenforceable, the remaining provisions of the Agreement shall remain in full force and effect, and the

如果协议的任何条款无效或不能执行的，其他条款仍然完全有效。

If therefore the executive, who has the power of convoking the legislative, observing rather the true proportion, than fashion of representation, regulates, not by old custom, but true reason, the number of members, in all places that have a right to be distinctly represented, which no part of the people however incorporated can pretend to, but in proportion to the assistance which it affords to the public, it cannot be judged to have set up a new legislative, but to have restored the old and true one, and to have rectified the disorders which succession of time had insensibly, as well as inevitably introduced: For it being the interest as well as intention of the people, to have a fair and equal representative; whoever brings it nearest to that, is an undoubted friend to, and establisher of the government, and cannot miss the consent and approbation of the community; prerogative being nothing but a power, in the hands of the prince, to provide for the public good, in such cases, which depending upon unforeseen and uncertain occurrences, certain and unalterable laws could not safely direct; whatsoever shall be done manifestly for the good of the people, and the establishing the government upon its true foundations, is, and always will be, just prerogative.

所以，如果拥有召集立法权力的执行权力，遵从真正的比例而不是代表制的表面形式，根据真正的理性而不是旧的习俗来管理所有有权利被清楚的代表的地方的代表人数，这种代表人数任何地方都不能自我宣称，而必须与它提供给公众的支持相称，这不能被认为是建立了一种新的立法权力，而是恢复了旧的和真正的立法权力，并矫正了由于时间流逝不知不觉所继承的和不可避免的引入所产生的混乱：因为既然拥有公正和平等的代表机构是人们的利益和意图所在；无论是谁使它更接近这一目标，谁便无可置疑的是这样的政府的朋友和奠基者，并不会得不到共同体的同意和许可；特殊权力也仅仅是一种权力，在取决于无法预见和不确定的事件的情况下，确定的和不可变更的法律不能安全的引导，于是君主行使它来为公众的利益服务；无论做什么，只要明显的是为人们的利益并将政府建于它真正的基础之上，是并且总是正当的特殊权力。

Men cease slaughtering one another, and that event is accompanied by the justification of the necessity of centralisation of power, of resistance to Europe, and so on. Men march from west to east, killing their fellow-creatures, and this event is accompanied by phrases about the glory of France, the baseness of England, and so on.

我们以为一个事件的发生是由于它的前一道命令所引起的，这个错误的观念之所以产生，是由于我们只看见事件发生了，在成千上万条的命令中，只有几条与事件有联系的命令得到了执行，却忘记了由于不能执行而未被执行的那一些。
