Provided are carbide derived carbon materials prepared by thermochemically reacting carbide compounds and a halogen containing gas and extracting all atoms of the carbide compounds except carbon atoms, wherein the intensity ratios of the graphite G band at 1590 cm -1 to the disordered-induced D band at 1350 cm-1 are in the range of 0.3 through 5 when the carbide derived carbon is analyzed using Raman peak analysis, wherein the BET surface area of the carbide derived carbon is 1000 m 2 /g or more, wherein a weak peak or wide single peak of the graphite (002) surface is seen at 2 = 25 DEG when the carbide derived carbon is analyzed using X-ray diffractometry, and wherein the electron diffraction pattern of the carbide derived carbon is the halo pattern typical of amorphous carbon when the carbide derived carbon is analyzed using electron microscopy.

提供了得自碳化物的碳，其通过热化学反应碳化物化合物和含卤族元素的气体并提取除了碳原子之外的碳化物化合物的全部原子制备，其中当使用拉曼峰分析法分析该得自碳化物的碳时，在1590cm -1 的石墨G波段与在1350cm -1 的无序引发的D波段的强度比为0.3至5，其中该得自碳化物的碳的BET表面积是1000m 2 /g或更大，其中当使用X射线衍射法分析该得自碳化物的碳时，在2θ＝25°观察到石墨(002)面的弱峰或宽单峰，以及其中当使用电子显微法分析该得自碳化物的碳时，得自碳化物的碳的电子衍射图是代表无定形碳的晕图案。该发射体具有良好的均匀性和长寿命。可以使用比用于生产常规碳纳米管的方法更廉价的方法制备发射体。

This chapter starts with the determination of primary sense of under. Then it focuses on how its spatial senses are extended from the central image schema to its transformations by metonymy. Next, this part also focuses on how its metaphorical senses are extended in terms of the central image schema and transformations by metaphor. In these analyses, this thesis summarizes four kinds of relations: the relation of UP-DOWN, the relation of HIGH-LOW, COVERING relation or the relation of IN-OUT and the relation of SOURCE-PATH-GOAL. Lots of metaphorical senses of under are derived from these basic spatial relations. In this thesis, the relations between the senses derived from central image schema and those derived from its transformations are explored at length. The relations between the spatial senses derived from central image schema and transformations and the metaphorical senses derived from them are also explored at length. The above analyses demonstrate that the sense extension of the spatial preposition is motivated by image schema, which also provides the root for metonymic and metaphorical extension. The semantic network of under is diagramed finally.

论文首先确定了under的首要意义；然后集中探讨了它的空间意义如何从中心意象图式，通过转喻形成许多变体，从而得以延伸；接着分析了它的隐喻意义如何从中心意象图式及其变体通过隐喻而得以延伸，在此分析中，本论文总结了四种关系：上—下关系﹑高—低关系﹑覆盖关系或里—外关系和起点—路径—目标关系，under的很多隐喻意义源于这些基本的空间关系；本论文还对源于中心意象图式的空间意义与源于其变体的空间意义的关系进行了详细的剖析；对源于中心意象图式与其变体的空间意义及其延伸的隐喻意义之间的关系，也同样进行了详细的剖析；通过分析论证了，意象图式是空间介词义项扩展的源泉，同时也为转喻和隐喻提供了基础；最后得出under的语义网络。

Two merging methods of Bézier curves are generalized to tensor product Bé zier surfaces, we propose two methods to approximate two pieces of adjacent tensor product Bézier surfaces by a piece of tensor product Bézier surface. We offer the explicit formulas of the merged tensor product Bézier surfaces with all kinds of merging conditions.

同样，Bézier曲线的两种合并方法也被成功的推广到张量积Bézier曲面上，得到把两片相邻张量积Bézier曲面合并成一片张量积Bézier曲面的两种合并方法，并给出在各种合并条件下的合并曲面控制顶点的显示表示式。
