摘要：　　一书(美:丹尼尔·平克)提出了"创感能力"的概念,它由"设计感"、"故事感"、"交响能力"、"共情能力"、"娱乐感"、"探寻意义"六部分组成.这个概念将越来越主导我们的学习生活,重塑我们的学习世界.在初中向量教学中,我尝试将其中"三感"融入于课堂,唤醒课堂的生命力.……

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.
