拟古写真交融奇辞奥旨同辉——韩愈《琴操十首》的审美观照     

杜兴梅  杜运通 《周口师范学院学报》2011,28(3)

韩愈的<琴操十首>是我国历代琴操诗的扛鼎之作.它借古鏊今,笞挞现实社会中的佞人专权,表达诗人憧憬圣贤的诉求;它巧妙地化用本事抒怀,展现了诗人的忠君意识、遗弃意识、反省意识和自赎意识相互交织的独特心灵世界;它奇辞与奥旨同辉,生命与意象叠印,以无我凸显自我,从而做到了古今贯通,物我无间,使音乐与诗歌完美地结合在一起,极大地推动了我国音乐文学的发展.  相似文献   

2000—2019年青藏高原积雪时空变化     

叶红  易桂花  张廷斌  周小兵  李景吉  别小娟  申一林  杨正兰 《资源科学》2020,42(12):2434-2450

积雪是冰冻圈最重要的组成部分,影响着大气环流和区域水量平衡,对气候变化十分敏感。本文基于2000—2019年MODIS/Terra积雪产品数据,探讨了青藏高原近20年积雪的年内、年际和季节性时空特征及其变化趋势。结果表明：①2000—2019年青藏高原积雪以短期积雪为主,积雪期在1个月及以下时间段内的积雪空间分布范围最广,占积雪总面积的72.91%;积雪期越长,多年平均积雪率（SCR）越高,SCR呈高原四周山脉高,而羌塘高原、江河源区、柴达木-黄湟高中盆地等地低的特点。②2000—2019年积雪面积呈反复的先波动增加再波动减少,距平变化率在-15.97%~11.52%之间。横断山区、帕米尔高原以及羌塘高原大部分地区的SCR呈明显减少趋势;高原四周极大/大起伏高山/极高山区、江河源丘状高山原和江河上游中/大起伏高山区的SCR呈显著增加趋势。③年内积雪面积呈双峰型周期变化趋势,3月和11月达到峰值,8月达到谷值,与该区域多年平均气温、降水等气候因子的年内周期性变化相反。青藏高原冬季积雪分布最广,秋季和春季积雪范围次之,夏季积雪范围最小;2000—2019年,青藏高原东部和南部冬季积雪显著增加、秋季和春季积雪显著减少,青藏高原整体夏季积雪显著减少。④近20年,青藏高原积雪与气温、降水的相关程度均较强,积雪覆盖范围与气温呈负相关关系,与降水呈正相关关系。研究结果有助于掌握青藏高原冰雪融水变化情况,对区域水量平衡和气候变化有重要指示作用。  相似文献   

“None of the Kings on Earth is Their Equal in ʿaṣabiyya”: The Mongols in Ibn Khaldūn's Works     

Josephine van den Bent 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(2):171-186

The rise of the Mongol empire was a shock to the Arab world and led many Arab authors to describe these conquerors in decidedly negative terms. The great historian Ibn Khaldūn also discusses the Mongols' rise and their conquests. As a nomadic people they challenged and defeated sedentary populations and founded their own dynasties. Consequently, the Mongol conquests perfectly fit Ibn Khaldūn's theories on ?a?abiyya – which is superior in nomadic groups – and the rise and fall of dynasties. For the Maghrebi historian, the rise of the Mongols was a natural step in the course of history. This consequently colours his view of the Mongols and affects the way he portrays them, especially regarding the themes of violence and religion – recurring themes in many contemporary works dealing with the Mongols – and in his depiction of the Turco-Mongolian conqueror Timur, who is presented in a more favourable light by Ibn Khaldūn than he is in many contemporary works.  相似文献   

析100m速度特征之加速跑距离及其步态变化     

李广文 《湖北体育科技》2010,29(1):70-72

通过对世界优秀运动员100m速度特征及其相关报道的结论与分析得出结论：1当代100m跑加速跑距离的研究室一个误区，加速跑距离长是高水平运动员最大速度大的外在表现特征，不能通过调整加速步态而达到提高成绩的目的；2运动员加速能力强的特征是加速度大而不是加速距离长；3步态特征之步长步频的变化是运动员高速跑中的自然协调，步长和步频应该作为一个整体来理解才有意义，简单的定论步长与步频谁代表了短跑的发展方向是误导；4建议100m训练重点放在技术与最大速度训练上，尽可能的发展动作速度．  相似文献   

The Byzantines and Saladin: Some Further Arguments     

Savvas Neocleous 《Al-Masaq: Islam & the Medieval Mediterranean》2013,25(2):204-221

This is the second of two articles by the same author arguing against the thesis that there was a conspiracy between the Byzantine emperors and Saladin, sultan of Egypt and Syria, against the crusader states and the Third Crusade in the 1180s. While the focus of the first article was primarily on the Latin sources, the present study shifts the focus to the Arabic primary material, hitherto largely neglected or inadequately treated by modern historians. Through a critical re-examination and re-interpretation of the Arabic sources, backed by the introduction and discussion of new Latin material when necessary, this article presents expanded arguments on the relations between the Byzantine Empire, the Sultanate of Konya and Saladin in the 1180s. The conclusions lend further support to the view that the Byzantine rulers and Saladin never concluded an alliance against the Latin settlers of Outremer and the Third Crusade.  相似文献

Islamic Historians of the Ayyūbid Era and Muslim Rulers from the Early Crusading Period: A Study in the Use of History     

Alex Mallett 《Al-Masaq: Islam & the Medieval Mediterranean》2012,24(3):241-252

This article examines the presentation of Muslim rulers from the early crusading period, 490–540/1097–1146 in six of the main chronicles written during the first half of the seventh/thirteenth century. It discusses the themes, ideas and topoi in each, demonstrating that the historians appear to have been divided into two ‘camps’ over their presentation of these rulers, based on their personal views of the rulers of their time. The article also examines why this division may have occurred, and considers its ramifications for modern scholarship of Arabic historiography, Islamic history and the history of the Crusades, in both the sixth/twelfth and seventh/thirteenth centuries.  相似文献
