摘要：结合北京地铁既有车辆基地的供热能耗特点,建立了新建车辆基地的供热模型,从绿色低碳角度分析了分布式耦合供热方案的节能降碳潜力。该供热方案满足北京市的相关供热政策,且达到了《中国城市轨道交通绿色城轨发展行动方案》规定的绿色能源利用指标要求,是未来寒冷地区车辆基地低碳供热发展的方向之一。

摘要：Isolated cationic Pd species encapsulated in MFI zeolite,i.e.,Pd@MFI,have been successfully prepared via in situ hydrothermal route followed by oxidative *** as-prepared Pd@MFI samples are investigated as promising catalysts in the reaction of methane ***,Pd@H-ZSM-5 shows remarkable activity in methane catalytic combustion with a low apparent activation energy value of 70.7 kj/mol as well as good catalytic stability even in excess water *** characterization results demonstrate the strong interaction between Pd sites and zeolite framework in Pd@ZSM-5 and the efficient stabilization of isolated Pd sites by zeolite *** analyses reveal that the presence of BrΦnsted acid sites is beneficial to methane adsorption and its subsequent activation on adjacent Pd sites,constructing cooperation between Bronsted acid sites and Pd sites within the confined space of MFI zeolite toward high-efficiency methane catalytic *** reaction mechanism of methane combustion catalyzed by Pd@H-ZSM-5 model catalyst is finally discussed.

摘要：采用文献回顾、问卷调查、深度访谈等研究方法,确定了衡量品牌体验的3个维度:实用认知体验、外观体验、广告体验。在此基础之上建立了品牌体验各维度对品牌忠诚的影响机制模型,对该模型进行了实证检验。结果表明,品牌体验量表具有良好的信效度;品牌体验各维度对品牌忠诚存在不同的影响效应。
