The apparent quantum efficiency of SO〓〓/TiO〓 was 10 times of that of TiO〓 catalyst for the photocatalytic degradation of bromomethane. Therefore, the SO〓〓/TiO〓 superacid catalyst is promising for practical application in environmental remediation.It was found that both L and B acid sites exist on SO〓〓/TiO〓 photocatalyst while only L acid sites on TiO〓 photocatalyst. On the basis of experimental results, the synergistic model of superacidic centers was proposed for SO〓〓/TiO〓 photocatalyst to explain the photocatalytic behavior and the mechanism of superacidifing effects, assuming that the adjacent L and B acid sites induced by SO〓〓 comprise cooperatively the superacidic center on superacid photocatalyst. The group cooperation of the superacidic center could strengthen the surface acidity, increase surface acid sites and the adsorbtion of O〓, promote separation of photogenerated electron-hole pair, enhance the interfacial transfer of charges and reversibility of water adsorption. Consequently the excellent photocatalytic activity, reaction stability and resistibility to humidity of SO〓〓/TiO〓 superacid photocatalyst may attributed to the group cooperated effect of the superacidic center on the photocatalyst.

研究结果表明：SO〓〓与TiO〓表面的结合为螯合式双配位结构；TiO〓光催化剂表面经H〓SO〓浸渍处理后，提高了表面酸性，改善了催化剂结构和光催化性能，当H〓SO〓浸渍浓度为1.0mol.L〓、烧结温度为450℃时，可制得SO〓〓/TiO〓超强酸催化剂(H〓＜-12.14)，其结构和光催化活性得到明显改善，与TiO〓相比，SO〓〓/TiO〓光催化剂的锐钛矿含量高、晶粒小、BET比表面积大、孔径分布集中、光谱吸收边蓝移，具有优异的光催化氧化活性、稳定性及抗湿性能，光催化降解溴代甲烷的表观量子效率比TiO〓催化剂提高了一个数量级，是一种有实际应用前景的高效光催化剂；由此提出了SO〓〓/TiO〓超强酸催化剂表面集团协同作用的超强酸中心模型，认为在SO〓〓/TiO〓超强酸催化剂表面，由SO〓〓诱导的相邻L酸中心和B酸中心组成了集团协同作用的超强酸中心，其集团协同作用显著地增强了催化剂表面酸性、增大了表面酸量及O〓吸附量、促进了光生电子和空穴的分离及界面电荷转移，具有可逆吸附水的性能，是SO〓〓/TiO〓超强酸催化剂具有优异的光催化氧化活性、很好的活性稳定性及抗湿性能的重要原因。

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。

While logocentrism, with sense as tool and induction and deduction as guidance, obtains comparatively deeper cognition than sense centralism (the cognition is not limited in partial images and is extended to such aspects as family and genus of the elephant.) Logocentrism is superior to sense centralism, but it is still a kind of very limited method of cognition other than a kind of real whole logical thinking. It carries out cognition within sensation or a slight larger scope, while the materials obtained and used are very limited. To make up the shortage, it needs to isolate the limited materials obtained, and idealizes that the matters temporarily unavailable or hard to be involved in are non-existent.

而逻各斯中心主义以感官为工具以归纳演绎为主导得到了相比感官中心主义较完整深刻的认识（如大象的属和科及习性等而不再限于局部形象），逻各斯中心主义高于感官中心主义，但它仍然是非常有限的认识方法而并非是一种真正的整体逻辑思维，仍只在感官或稍大范围内进行着认知活动，所得到并运用的质料仍是有限的，为弥补不足，它还需要将所得到的有限质料孤立起来而将暂且不能得到或难以涉及的周围的东西理想化为不存在。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
