藏蒙汉宗教文化的相互交流及影响

藏传佛教文化渊源于汉地大乘佛教和南亚密教，在与土著本教几经较量后，形成独具一格的藏传佛教文化。由于自身的生命力和历史的政治风云影响，藏传佛教文化北扩、南下、东返，藏蒙汉文化交流融合历经千余年，使藏文化成为中华民族文化大家庭中不可分割的一部分。     

简评汉武帝的历史功过

从开边拓土、尊儒兴学、知人信佞、奢侈酷暴、悔悟改过等五个方面对汉武帝的历史功过进行评价,认为汉武帝五十多年的统治生涯中有功也有过,功大于过,不失为一位具有雄才大略的帝王和杰出的历史人物。尤其是他知过能改的精神,更值得后世人们学习借鉴。

NaCl沉积和SO2污染对镁合金初期大气腐蚀行为的影响

借助扫描电镜(SEM/EDX)、X射线衍射(XRD)研究了NaCl单个因素对镁合金AZ91D初期腐蚀行为的影响,并对SO2和NaCl的协同作用进行了探讨.NaCl存在时初期破坏金属表面的保护膜,但后期微溶性腐蚀产物的生成导致腐蚀速率的降低.当NaCl和SO2同时存在时,反应生成的可溶性产物不具有阻碍的作用,同时他们会发生部分溶解生成自由移动的离子,大量难溶物在镁合金表面难以短时间形成,故NaCl和SO2同时存在引起的腐蚀远大于两者单独存在时引起的腐蚀加和.NaCl和SO2对镁合金的初期大气腐蚀具有明显的协同作用.     

玉米自交系苗期耐旱性鉴定指标的模糊综合评价

以与玉米自交系幼苗质膜损伤程度有关的过氧化物酶、超氧化物歧化酶、过氧化氢酶、丙二醛、维生素C和电导率为指标，用模糊隶属函数法对玉米自交系的苗期耐旱性进行综合分析，结果表明，本试验所选择的6项指标，按隶属函数计算加权平均值的方法对参试自交系进行耐旱性综合评价是有效的。     

Rh-Catalyzed Decarbonylative Cross-Coupling between o-Carboranes and Twisted Amides: A Regioselective,Additive-Free,and Concise Late-Stage Carboranylation

The convenient cross-coupling of sp² or sp³ carbons with a specific boron vertex on carborane cage represents significant synthetic values and insurmountable challenges. In this work, we report an Rh-catalyzed reaction between o-carborane and N-acyl-glutarimides to construct various B_cage−C bonds. Under the optimized condition, the removable imine directing group (DG) leads to B(3)− or B(3,6)−C couplings, while the pyridyl DG leads to B(3,5)−Ar coupling. In particular, an unexpected rearrangement of amide reagent is observed in pyridyl directed B(4)−C(sp³) formation. This scalable protocol has many advantages, including easy access, the use of cheap and widely available coupling agents, no requirement of an external ligand, base or oxidant, high efficiency, and a broad substrate scope. Leveraging the Rh^I dimer and twisted amides, this method enables straightforward access to diversely substituted and therapeutically important carborane derivatives at boron site, and provides a highly valuable vista for carborane-based drug screening.     

文章世所希——晏殊之赋研究

北宋前期政坛、文坛领袖之一的晏殊常常仅被当作一个＂北宋倚声家之初祖＂的词人;其实晏殊残留下来的几篇赋体文章在铺陈、骈俪方面的艺术形式十分精美,颇具悠游富贵气象,鲜明具体的表现了北宋前期文坛学习李商隐骈文的情况。     

论汉末魏初人物评价标准的新变--以荐举文为中心

汉末魏初，荐举文书中的人物评价标准经过西汉对士人忠与谋的重视，东汉对士人自身秉性的认可而发展成为对士人清名的推崇。“清”成为汉魏易代之际士林人物品评的核心关键词。这种集中体现其时士人理想人格之“清”在承袭士人清白品性的传统意义之外，更增添了士人在乱世中激浊、厉俗的新内涵。汉末魏初士人思想的更新是“清”评形成的基础，而统治者对德高望重且清虚自守的士人的需求与召唤又加速了“清”评的形成。     

从汉画像石艺术的演变看汉代天人思想

汉画像石艺术图像中的描绘,不仅形象地再现了汉代各种文化的内容、形式、艺术特色,而且更深层地反映出汉代天人思想在其中的渗透和影响。     

Electrochemical Characterization of Egyptian Blue Pigment in Wall Paintings Using the Voltammetry of Microparticles Methodology

The solid state voltammetric response of Egypt blue, Han blue and ploss blue pigments upon attachment to graphite electrodes in contact with aqueous phosphate buffer at pH 7.0 is studied by voltammetry of microparticles and scanning electrochemical microscopy. Such voltammetric responses, combined with those for synthetic specimens consisting of binary mixtures of the pigment and SiO₂ or CaCO₃ as well as ternary ones of CaCO₃ and SiO₂ mixtures allow for the identification of the pigment and the support in samples from wall paintings using different electrochemical parameters, in particular upon performing the Tafel and modified Tafel analysis of voltammetric peaks. Identification of Egypt blue in microsamples of murals from a Roman archaeological site in Castulo (Jaén, Spain) is discussed.
