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.

The numerical results indicated that the mixing time decreases about linearly with increasing current intensity. The mixing time decreases first then increases with increasing current frequency and comes up to its minimum value at 30Hz. Applying the traveling magnetic field to the uptake or downtake when the exciting current intensity is 200 A at 10 Hz, the mixing time can be shortened by 9%~17%. With the operating conditions kept unchanged, shorter mixing time is available if applying the traveling magnetic field to the uptake instead of downtake, and the time can be shortened by 18%~26% if applying the magnetic field to both the uptake and downtake. Moreover, the mixing time decreases with increasing argon blowing flowrate, and the time comes down to its minimum value if the argon blowing flowrate is 1 600 NL/min. After the moment, the mixing time increases with argon blowing flowrate.

Pragmatic presupposition determines the choice of information focus and its position in a sentence,organizes the discourse into a coherent whole,concise,clear and smooth,and achieves the expected stylistic effects.in college english teaching,if teachers teach the knowledge about pragmatic presupposition in listening teaching,introduce the frequently-seen patterns of presupposition, increase the presuppositional sensitivity of students to certain words and structures,guide students to use the theory on presuppositional information to make forecasts on base of written listening material,listen purposefully,and get rid of the distraction of the minor and redundant information,the ability of students to obtain major information and linguistic inference will be strengthened and their listening competence will improve remarkably.george yule divided presuppositional triggers into factive presupposition,non-factive presupposition,counter-factive presupposition,existential presupposition,lexical presupposition and structural presupposition.presuppositional triggers are helpful for us to understand the true intention of the speaker or writer.in college english reading teaching,if teachers introduce the discourse organizing function of pragmatic presupposition and the relevant presupposition triggers,and teach students to use these triggers to communicate with the writer,the comprehension competence of students will be greatly enhanced.the essential function of presupposition is to build a framework for the further development of discourse.in college english writing teaching,teachers can use the theory on pragmatic presupposition to construct a handy training program for textual organization,increase the textual coherence, economy and structural perfection of the english writings by students.in college english translation teaching,teachers should focus on developing the pragmatic presuppositional thinking of students,enable them to grasp the presupposed information in source text / speech exactly,understand the original thoroughly,correctly reorganize and reproduce the pragmatic presuppositions in the target language,carry out the functional equivalence in translation and successfully realize the smooth and accurate communication.with the instruction of pragmatic presupposition in college english teaching,the complete understanding and integral acquisition of english and chinese of students will come true.in conclusion,to implement the curriculum requirements for college english teaching promulgated by the ministry of education of china,we should emphasize the instruction of the theory on pragmatic presupposition in college english teaching,carry it through from beginning to end.it's one of the important means to realize the college english teaching reform, improve the effects of college english teaching,strengthenr the practical and integrative language abilities of students,in order to cultivate the compound talents to adapt to the global integration and meet the requirements of the reform and opening in china.
