The math models of the tree structure chart and the net structure chart are formed by describing the different road state abstractly.The tree structure chart model is presented without consideration of U structure and ring structure. This kind of model has a notable feature: there is a line only between the two dot in the chart, which means that there is only one road from one point to another point in expressway ,so the tree structure chart is called "single roads chart".

According to the studied results at present, the studied objects are mainly thin plate and beam about sound radiation mode, a method computed sound radiation mode of complex structure is presented in this dissertation, according to the results of the previous two chapter, a theoretical method to solve acoustical radiation mode and acoustical radiation efficiency of complex structure by boundary element method and acoustical radiation theory is posed, the acoustical radiation power is expressed as a Hermitian quadratic form, while the radiation modes is determined by general eigenvalue decomposing, and then the radiation efficiency is computed via the orthodoxy of radiation modes with regard to impedance matrix and average velocity matrix; lastly, the validity of the method is proved by pulsating sphere and radiating cube with analytical results. According to results of the form three chapter, the structure sound radiation sensitivity is studied in detail, the sound radiation power of structure can be expressed as positive Hermitian quadratic form, the sound radiation sensitivity can be expressed as two parts by partial differential with respect to design variable, which are sensitivity of boundary velocity and impedance matrix, combined with the theory of FEM and BEM, the structure sound radiation can be translated to the analysis of structure dynamic sensitivity and impedance matrix sensitivity. The theory posted in this dissertation is tested by the FEM software ANSYS and the software AAS programmed by author.

Current researches show little attention to this structure and thus this paper is devoted to an overall understanding of this structure. The content of this thesis focuses on the following three aspects:First, when restricting the potential semantic range of noun phrases with its own proposition, the modifying clauses in English and Chinese share the same semantic features. That is to say, the modified noun phrase and the predicate of the clause depend on each other for existence. This semantic restrictiveness is obligatory for the clause and the noun phrase it modifies in both languages. Second, though sharing the same potential conceptual meaning, the combination of a clause and its modified noun phrase shows different syntactic position in surface structure as well as the inner structure of the clause. Based on a full description of syntactic characteristics of this kind of clause, the present thesis points out the differences and similarities existing in surface structure between English and Chinese. Finally, under the guidance of Chomskys Minimalist Program(1995), the thesis analyses the derivational processes of this structure in both languages.

In contemporary Chinese, the combination of Noun and Verb can constitute three different structures:"NV"nominal modifying structure,"NV"verbal modifying structure,"NV"subject-predicate structure. This structure is worthy of researching because the location of it's internal component's is dispute, that is to say, whether the headword of nounbial modifier structure is verb, and whether the headword of verbal modifying structure can be noun are disputable problems.

This paper discusses the dynamical characters of the RC mega-sub controlled structure. It is concluded that the deformation and the acceleration of vibration-absorption megaframe structure can be well reduced under the windward pulsoting wind load, through choosing the reasonable the member parameter and the accessional columns stiffness of the structure. So the safety of the structure is enhanced, and the comfortable need is satisfied. So the new mega-sub controlled structure is a kind of ideal super tall building structure configuration, it will have the bright future.
