Chinese folk art forms in modern architectural design

改革开放后，中国接受了很多新的西方理论冲击，致使中国本土的建筑形式大部分偏向西方化。经过这么多年的发展，慢慢结合实际，中国独有的特色也慢慢在建筑中得到体现，怎么样将建筑设计形成具有中国区域性特色、地方性特色、具有中国风的道路却依然漫长。建筑材料、建筑工具的进步和建筑方法的更新替代也给设计建造具有中国特色韵味的建筑带来了不小的难度和压力。我们要从中国悠久的历史文化、广博的哲学思想、丰富多彩的艺术造型中提取能够与现代设计理念，现代审美，现代制造工艺相符合的元素，灵活的不照抄照搬的，即不所谓”标签式”的运用。不脱离生活，满足当代人新的审美价值、新功能需求的来设计建造真正具有中国风的建筑外观和建筑室内...After the reform and open policy, China has accepted the many new western theory impact, causes the Chinese native place the construction form majority of deviation westernization, passes through such many year development, links to the reality slowly, the characteristic which China is in sole possession of also slowly in the construction obtains manifests, how will the architectural design form h...学位：文学硕士院系专业：艺术教育学院美术系_设计艺术学学号：1862008115353

南方住房中的微气象问题——以广州万科城尚东住宅楼户型为案例

选择一套房子,就是选择一种生活方式,处于这种环境中,除了房子自身的质量需要达标之外,还有许许多多的问题需要解决,如住宅外面的绿化环境,住宅内部的植物,住宅的位置朝向等等,这一些成分组成了住宅中的微气象问题。我们居住在房子中,难免会与住房及其周围的环境发生互动,这样一来就会产生微气候问题,如空气的流通、采光条件、湿度问题,夏冬日的蚊虫问题等等,本文阐述的就是以广州万科尚东城为例的南方住房中的微气象问题

Yang-Shi's Role in the Transition of Neo-Confucianism

杨时是两宋之交理学史的一位继往开来的人物，他曾先后受学于程颢、程颐，被时人推许为“程氏正宗”，在他一生的时光中，充满了为传承及播扬洛学所做的努力，贯穿了洛学由私学而成为禁学、再成为官学的这一系列地位变迁的全程；其在洛学南传入闽的过程中，在融摄理学诸家学说，从而使得理学的发展链条由二程而至朱熹的传承体系之中，都起到了无可替代的作用。本文主要分为三个部分来解析杨时在两宋之际的一连串动荡之中，为传承及播扬洛学所做的贡献。一，介绍杨时进行传承及播扬洛学活动时的历史背景，通过对于杨时在对二程典藉的整理，以及站在洛学学者的立场对于儒学典藉重新解注与发现上的功绩的讨论，说明其对于洛学传承与发展的影响。二，讨...Yang-Shi is a great philosopher who lived between the Northern Song and Southern Song Dynasty. He once successively studied “Neo-Confucianism” with the brothers Cheng Hao and Cheng Yi. In his whole life, there was filled with his effort that he had made to spread he his teacher's theory. From that time，Yang-Shi is considered as the best student of his two teachers, since he had obtained the most l...学位：哲学硕士院系专业：人文学院哲学系_中国哲学学号：20040500

Catalytic Performance of MoVBiTeO/SiO_2 for Selective Oxidation of Propane to Acrolein

[中文文摘]用浸渍法制备了一系列不同Mo/V比的MoVBiTeO/SiO2催化剂,并用X射线衍射、拉曼光谱、X射线光电子能谱、程序升温还原和红外光谱等方法对催化剂的结构、氧化还原性质和酸性进行了表征,考察了催化剂对丙烷选择氧化制丙烯醛反应的催化性能.结果表明,Mo与V组分之间存在较强的相互作用,调变了催化剂的结构,并形成了氧化还原循环(V5++Mo5+V4++Mo6+),促进了催化剂中电子和O物种的传递,使催化剂的低温可还原性增强,催化活性提高.Mo组分有利于形成L酸位,而V组分有利于形成B酸位.这可能是丙烯醛选择性随Mo/V比增大而逐渐提高的原因之一.当Mo/V摩尔比为6时,催化剂具有最高的丙烯醛收率(9.7%)。[英文文摘]A series of MoVBiTeO/SiO2 catalyst samples with different Mo/V ratios were prepared by the impregnation method.The catalyst structure,reducibility,and acidity were characterized by XRD,Raman,XPS,TPR,and FT-IR techniques,and the catalytic performance of the catalyst for selective oxidation of propane to acrolein was evaluated.The results indicated that the interaction between Mo and V components modified the catalyst structure,and the redox cycle of V5++Mo5+V4++Mo6+ was formed.The improvement in the reducibility of the catalyst might be responsible for the increase in propane conversion. The V and Mo components were responsible for B acid and L acid , respectively. When the Mo/ V ratio increased , the amount of B acid de2 creased , and the catalyst selectivity for acrolein increased. Among the investigated catalyst samples , the sample with a Mo/ V molar ratio of 6 exhibited the best catalytic performance.国家重点基础研究发展计划(2005CB221408); 国家自然科学基金(20433030,20021002,20423002); 福建省科技重大专项(2005HZ01-3)

WAN Hui-Lin, Email: [email protected]; Tel: +86-592-2186569.[中文文摘]采用浸渍法通过改变焙烧气氛制备了系列NiO/SBA-15(wNiO=20%)催化剂,并考察了催化剂的丙烷氧化脱氢(ODHP)反应性能.实验结果表明,与在静止和流动空气中焙烧的催化剂相比,在1%NO/He(VNO/VHe=1:99)气氛中焙烧的NiO/SBA-15-NO具有优异的低温丙烷氧化脱氢制丙烯性能,在350°C时,丙烷的转化率和丙烯收率分别约达29%和13%.反应温度升至450°C时,丙烯的选择性仍保持在45%左右.X射线粉末衍射(XRD)和透射电镜(TEM)测试结果表明,1%NO/He气氛可有效抑制焙烧过程中NiO纳米颗粒的团聚,使NiO物种高分散于SBA-15的孔道中.H2-程序升温还原(H2-TPR)和O2-程序升温脱附(O2-TPD)测试结果表明,随着NiO在SBA-15上分散度的提高,催化剂的抗还原性增强,ODHP活性氧物种O-的含量增加,进而使1%NO/He气氛中焙烧的NiO/SBA-15-NO在较宽的温度范围内(350-450°C)均具有良好的丙烯选择性,并显著提高了催化剂的低温活性. [英文文摘]A series of NiO/SBA-15 (wNiO=20%) catalysts were prepared by impregnating SBA-15 with an aqueous solution of nickel nitrate followed by calcining under three different atmospheres. The resulting materials were studied with regard to the oxidative dehydrogenation of propane (ODHP) to propylene.Compared to the catalysts calcined under either static or moving air, the NiO/SBA-15-NO catalyst calcined under flowing 1%NO/He (VNO/VHe=1:99) atmosphere demonstrated greater activity for this reaction at low temperature. Propylene yield of ~13% with propane conversion of ~29% was obtained at 350 °C and the propylene selectivity remained at about 45% even when the reaction temperature was raised to 450 °C.X-ray diffraction (XRD), transmission electron microscopy (TEM), H2-temperature program reduction (H2-TPR), and O2-temperature program desorption (O2-TPD) characterizations were used to investigate the intrinsic differences between these NiO/SBA-15 catalysts. It was found that NiO species in the catalyst calcined under 1%NO/He atmosphere were highly dispersed inside the mesopores of SBA-15. With the increasing of NiO dispersion on the support, the quantity of NiO species with a reduction temperature above 450 °C increased significantly. In addition, the density of O- species on the catalyst calcined under 1%NO/He was much higher than that in the case of the other two samples. These factors are responsible for the superior performance of the NiO/SBA-15-NO catalyst for the ODHP reaction over the temperature range 350 to 450 °C.国家重点基础研究发展计划(973)(2010CB732303);国家自然科学基金(21173173,21073148,21033006);教育部创新团队项目(IRT1036);福建省重大科技专项(2009HZ0002-1)资助项

丙烷选择氧化制丙烯醛MoBiTeO/SiO_2催化剂中Te组分的作用

用浸渍法制备了一系列不同Te含量的MoBiTeO/SiO2催化剂,并用XRD、Raman、XPS、NH3-TPD、吡啶吸附FT-IR和催化剂性能评价等方法考察了Te组分对催化剂的结构、酸性及其丙烷选择氧化制丙烯醛性能的影响.结果表明,催化剂中Mo氧化物与Te氧化物之间发生了相互作用,通过形成Mo—O—Te桥氧键生成了Te多钼酸盐物种,在一定程度上分散了Mo-O活性中心,同时TeOx具有脱除丙烯α-H、插氧并将其转化为丙烯醛的功能,因此,在MoBiO/SiO2催化剂中添加Te组分使丙烯醛选择性有显著的提高.但是Te的加入同时也使催化剂中B酸增强,这不利于丙烯醛生成.因此,Te添加量有一最佳范围,nTe/nMo为0.05-0.1时催化剂具有较好的催化性能
