腺苷A2A受体阻断剂SCH58261对大鼠杏仁核点燃癫痫模型的影响
Zhongguo shiyan zhenduanxue, 2015 目的研究腺苷A2A受体阻断剂SCH58261对大鼠杏仁核点燃癫痫模型的作用。方法制作杏仁核电刺激模型。点燃成功后的大鼠,通过腹腔给药的方法,观察SCH58261对模型成功后各发作参数的作用。整个实验过程中,严密观察药物对大鼠行为学的影响。结果在成功点燃的癫痫模型中,SCH58261（0.005,0.05,0.5mg/kg）对全面性发作阈值（GST）没有影响。以GST（+4μA）为刺激强度,SCH58261（0.005,0.05mg/kg）可以降低杏仁核后放电时间（ADD）,运动性发作持续时间（MSD ...

Rare Metals, EarlyView.ABSTRACT Organic‐inorganic hybrid perovskites (OIHPs) with white‐light emission have significant potential in solid‐state lighting and display due to the designable structure and excellent luminescent properties. However, OIHPs are prone to damage during bending due to the brittleness of crystals, which limits their application in the field of flexible

论外国文学研究“中国化”的逻辑起点及其启示——以1920—1930年代的“小国文学”研究为例 [PDF]
学界一般认为,外国文学研究"中国化"的起点是郑振铎的《文学大纲》,然而今日外国文学研究的"中国化"理论和实践,从逻辑上与郑振铎并非一脉相承。对早期外国文学研究史料的爬梳和分析表明,外国文学研究"中国化"的逻辑起点应当是"小国文学"研究。1920—1930年代,中国的外国文学研究界延续了"五四"以来对于"小国文学"的偏爱,以期望获得对中国社会有帮助的经验。"小国文学"研究奠定了外国文学研究的基础,并为外国文学研究"中国化"提供了可能的路径,但政治化与时代化两大特征,也是其历史局限性所在 ...

Research on Investigation and Post-Occupancy Evaluation of the Waiting Space in Xiamen Railway Station [PDF]
, 2016 随着陆上交通方式飞速发展，高铁、动车逐渐成为人们出行的主要交通工具，大量老火车站因功能、空间的不足遭到废弃，对老火车站的改扩建进入一个全新的阶段。候车空间作为火车站公共空间中与乘客联系最紧密的一环，也将面临火车站功能、空间更新和人们出行理念变革所带来的一系列新问题。 本文以厦门站候车空间为研究对象，在相关理论研究的基础上，对厦门站候车空间展开实地调研。基于调研结果对其进行使用后评价研究，从中总结厦门站候车空间存在的问题，并提出优化策略。希望通过此次研究对候车空间的设计和使用后评价理论的完善做出一定贡献。
