摘　　要：将固体熔融法合成的2,3,9,10,16, 17,23,24-八羧基酜菁铁（FcPc（CCOH））敏化二氧化钛制备了酜 菁铁二氧化钛催化剂.通过UV、F11R、PL、XRD、DRS、XPS和化吸附-脱附等-系列实验方法对催化剂进行了表征 和催化性能分析.在可见光条件下研究了八羧基酜菁铁（ FcPc（COOH ）8 ）敏化的 TiO2催化剂对亚甲基蓝（ MB）、罗丹明B（RB）、中性红（ NR ）、酸性红（ AR ）和孔雀石绿（ MG ）水溶液的降解动力学.研究结果表明在z=100min时,此光催化剂降解这四种有机染料均有良好的效果.染料降解动力学曲线拟合表明此光催化降解过程符合一级化学反 应动力学方程,其降解 MB、RB、NR、AR和MG动力学常数分别为0. 04359、0. 03508、0. 01901、0. 01302 min^-1和 0. 00968 min^-1.The 'pile-to-column'structural replacement is usually required in basement extension project and the pile cap joint becomes a key part of the reconstruction.In order to analyze stress variation of weak area of pile cap joint,a mechanical analysis model for one-pile-one-column pile cap joints is established.Then,Finite Element Method and the element birth and death technology are utilized to solve stress distribution of pile cap joint in different construction phases of a high-rise building.Finally,causes of the weak area as well as its stress variation pattern are analyzed according to the solving result.The following conclusions are drawn through this study:stress level of core area increases significantly during the replacement beam-column joints;the stress path in the core area is affected by different construction steps.
