At present,a large number of historic buildings on campus are lack of energy-saving measures from the design time,especially the dormitories. And the reconstruction mostly focuses on functional reorganization or furniture replacement. However,energy efficiency design has not been paid enough attention,which leads to the high building energy consumption and the harsh physical environment. Based on the analysis of climatic characteristics of Chongqing area,taking Dormitory Six on campus B of Chongqing University as an example,the reconstruction of rooms on the top floor and West end are focused to guarantee the equal benefits of the dormitory environment. Through the simulation analysis of the software, on the basis of energy saving reconstruction of common maintenance structure,this thesis discusses the energy saving reconstruction methods and strategies of the existing campus dormitories,which are more suitable for the existing campus dormitories in Chongqing area.

考察了纳米碳纤维(CNF)、活性炭、石墨以及CNF负载磷氧化物催化剂催化丙烷氧化脱氢(ODP)反应性能。采用SEM、HRTEM、XRD、TG和BET表征了催化剂的组成和结构。结果表明炭材料自身对于ODP过程具有较高的活性和选择性,尤其是CNF由于其独特的结构特点更适合用作ODP过程催化剂。负载磷氧化物提高了CNF催化剂的适用温度,并提高了丙烯产得率。以磷酸氢二铵为前驱体,负载于经液相氧化处理的CNF上可以得到高选择性的ODP过程催化剂,在500℃下,丙烷转化率为42.07%时,丙烯选择性达到39.63%。
