摘要：The development of efficient oxygen evolution electrocatalysts with reduced noble metal uses is a critical challenge for the deployment of various advanced energy conversion ***,a series of lanthanide-contained 6H-perovskites with a formula of Ba3LnIr2〇9(Ln=lanthanides)are investigated as oxygen evolution electrocatalysts,whose active subunits(i.e.,face-sharing Ir〇6 dimers)can be regulated by the lanthanides in terms of catalytic *** using density functional theory(DFT)calculations,we establish the theoretical trend in activity for Ba3LnIr2〇96H-perovskites,the activity of which is correlated with the difference of adsorption free energy(△G〇-△Goh)between O*and OH*reaction *** further establish a volcano curve between△Go—△Goh and the calculated 0 p-band center Among the Ba3LnIr2〇96H-perovskites,Ba3Lalr2〇9 locates at the peak of volcano curve,and correspondingly is the most active electrocatalyst due to the optimal 0 p-band property.

摘要：印章档案,是指国家机构、社会组织和个人在从事政治、军事、经济、科学、技术、文化、宗教等社会活动中形成和使用过的印章,是一种具有特殊载体形态并在历史研究、档案考证、文物收藏和艺术鉴赏等方面有着特殊价值的档案。印章档案是档案管理工作中的有机组成部分,是档案文化的一个重要方面。

摘要：当前,中国学界对"民间宗教故事"的研究还较少,我们以崂山民间宗教故事为主要考察对象,联系民众观念中的宗教和历史上著名的佛道之争中体现的民众智慧,认为民间故事与社会生活双重变奏的主要表现是,民间故事中表现出来的社会生活鲜活立体,民众创造的故事反映了民众的部分生活史,而这要远比正史的史料记载要鲜活生动并且可信性大得多。
