Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature. Finally, we will employ the Minkowskis support function to construct a new kind of non-circular smooth constant breadth curves in order to attack some open problems on the constant width curves for example, whether there is a non-circular polynomial curve of constant width, etc.

Based on investigating the short and intermittent structural plane, surrounding rockmass of the huge underground powerhouse in Three Gorge has been divided into five statistical similar areas according to its characteristic of rockmass structure by applying structure plane network simulation. Distributed characteristic of structural plane has been studied and based on it mechanics macrocharacteristic has been studied:(1) It is the first time that based on the result of structural plane network simulation rockmass quality of every structure area has been studied with applying blurred information optimum seeking technique and be compared with and RQD method. The result indicated that it has better effect to evaluate rock quality with blurred information optimum seeking technique.(2) It is the first time that the interrelated relationship of the result of in-suit rockmass deformation test and fractal characteristic of structure on test point has been applied to determine rockmass deformation parameter. The question of evaluating deformation parameters of engineering rockmass has been solved.(3) Anisotropy strength parameters have been determined by applying shear zones simulating method. The result indicated that there are different strength parameters in every structural area, after comparing the result of Fast Lagranian Analysis in continua number simulation method with that of method of weighted mean according to continuity. The result indicated that when a suitable reduction coefficient is been considered rockmass strength parameters can be simply and fast determined with method of weighted mean according to continuity where there is not enough test result.(4) Damage characteristic has been studied based on analysis fractal characteristic of structural plane network by applying fractal-damage coupling method. It is the first time that the concept of damage degree has been set up to evaluate rockmass quality according to the biggest principal damage.

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.

Levine argues that the gap is an epistemological one that is compatible with the thesis that facts about consciousness supervene on the physical facts, while Jackson and Chalmers argue that the fact that there can be no conceptual analysis of consciousness supports metaphysical dualism: consciousness is neither identical with nor supervenient on the physical.

Levine認為這個鴻溝是認識上的影音先锋黄色网站nqdai.cn，相容于'意識是附加在物理事實上的依附事實'的主張，而Jackson and Chalmers認為意識的不可概念分析支持形上學二元論：意識不是同一于也不是附著于物理物上91色噜噜狠狠狠狠色综合。
