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.

With these discussions, the author concludes that given the complexity and contradiction of the architecture discipline, it is true that we may find it impossible to make a definite 'pro' or 'con' on structural correctness. But with its inherent resonance to high-resource-effiency and sustainability, structural correctness is not at all a non-sequitur in contemporary architectural critique.

The thesis consists of six chapters. In the first, the technologies of atomic force microscopy and of the measurement elasticity of biomolecules were introduced. In the second, the validity of VSPFM was confirmed by lift mode atomic force microscopy. In this chapter, the height of DNA was measured by lift mode atomic force microscopy, which demonstrated that the method of height measurement of biomolecules by VSPFM was correct and established the foundation of the method of measurement elasticity of biomolecules by vibrating mode scanning polarization force microscopy. In the third chapter, detailed work has been illustrated on the foundation of the method of measurement elasticity of biomolecules by VSPFM. And the compressive elasticity of DNA was measured. In fourth and fifth chapters, the method was applied in the measurement elasticity of proteins. Two proteins elasticity, fibre-like protein α-synuclein and global protein IgG, were measured by VSPFM, through which the method wound its way to the application of biomolecules. In last chapter, the final part of the thesis was a summary. A conclusion of the thesis and a self-comment on my work as a PhD candidate have been made, and expectation about the further works has been addressed.
