端砚，肇庆人的骄傲

肇庆人对来肇庆的人的话题是离不开端砚的,那是他们的骄傲。 天下人都知端砚,未必知端州,都知道端砚,却未必都见过端砚。我是见过端砚的,我又不大确信见过的 真就是端砚。到肇庆,到古端州,憋足了劲,就想好好看看端砚。     

三晋伐齐前后齐国一方人物史迹初考——以清华简《系年》为中心

三晋伐齐是先秦时期发生的一个重要事件。然而,由于经历秦始皇焚书坑儒,很多历史文献丧失殆尽,与之相关的众多人物和问题变得扑朔迷离。清华简《系年》中,则有许多三晋伐齐前后人物与史事的原始信息。以置身其中的齐国一方的人物及相关问题为例,通过对《系年》和相关传世文献的对读与研讨,不仅可以了解到三晋伐齐期间发生的"陈子牛之祸"的具体细节,揭示"和子之乱"的真相,补证田齐世系,还能在当时的背景下,将楚声王熊当的一系列相关活动合理纳入其中。凡此种种,无不表明清华简《系年》对于先秦史研究具有重要价值。     

从阿拉善旗专员到军事专员:南京国民政府介入蒙旗地方政治的尝试

为防止日本侵略势力的渗透,南京国民政府创设了阿拉善旗专员制度。因专员在派驻过程中,遭遇层层阻碍,最终被迫改置为军事专员,权责缩减。专员制度作为南京国民政府介入阿拉善旗地方政治的首次尝试,其尴尬境地也反映了在缺乏稳定环境与足够控制力的条件下,边疆政治整合所面临的困境。军事专员虽远未实现其设置的预期目的,但客观上有利于加强中央与阿拉善旗地方联系,从而有效地维护了边疆主权与统一。     

A Spectral-Acceleration-Based Linear Combination-Type Earthquake Intensity Measure for High-Rise Buildings

With the consideration of higher modes, an attempt is made to develop a spectral-acceleration-based linear combination-type earthquake intensity measure (IM) for high-rise buildings. The modal mass participation factors are determined to take weighting coefficients. A parametric analysis on the correlation between IM and the maximum interstory drift that utilizes the bend-shear coupled continuum model yields a bilinear relationship between the optimal number of modes involved and structural fundamental period. The proposed IM and several other combination-type IMs are shown to be efficient and sufficient, while the scaling robustness of the proposed IM is more stable compared with that of fundamental-mode-based IMs.     

A scientific analysis of cranial trepanation from an Early Iron Age cemetery on the ancient Silk Road in Xinjiang,China

This study uses multiple scientific methods to analyse a case of trepanation from a cemetery located at the westernmost point along the ancient Silk Road in China dating back to the Early Iron Age. The skull of interest belonged to a middle-aged male; the opening is located on the left posterior side of the skull in the occipital bone. Computer tomography (CT) and microscopic observation show that the incision was unhealed, indicating an immediate death either during or after the operation. The procedure of trepanation might have been used to treat a depressed fracture from inflicted trauma on the individual’s right parietal bone, suggesting the presence of surgical trepanation in early Western China.     

Study on the valuation of livestock production in the Tibetan Plateau

I.Introduction
Three villages were selected to do the field research in Tibet Autonomous Region： Khorchak village and Shide Village in Purang Town, Purang County, and Kungyal Village in Hor County. Close to India and IO km from Nepal, the first two villages, Khorchak and Shide, are situated I8 kilometers from Purang County, along the downstream of Peacock River, one of the four major rivers in All. With average altitude of 3850 meters in plateau subfrigid arid climate, these two beautiful villages fall into the category of farming- pastoral area and their productive structure is settled/grazing, herding sheep, goat, cow and etc. Kungyal Village, II5 kilometers to the east of Purang County government, altitude 4670, plateau subfrigid arid climate, is a typical pastoral area and its productive structure is nomad or seasonal nomad, herding yak, sheep goat and etc. These three villages were chosen due to their representative features.     

沈阳故宫缂丝书画作品赏析

中国的缂丝工艺历史悠久,工艺精美,具有很高的历史、艺术和实用价值,备受人们的喜爱。缂丝又称"克丝"或"刻丝"。是以彩纬显现花纹,形成花纹边界,具有雕琢镂刻的效果,且富有双面立体感的丝织工艺品。缂丝的编织方法不同于织棉和刺绣,是采用"通经回纬"的织     

纵贯历史：辛亥前后的铁路国有

1911年,由铁路国有引发的保路运动,正是辛亥革命爆发的导火线,辛亥革命则导致了清朝的灭亡。不过,铁路国有的政策却并未成为清帝国倒台的殉葬品。民国建立以后,铁路国有化的整体趋势却是不可逆转的。铁路国有在清朝和民国的不同命运,揭示了辛亥前后政治格局的变动。     

《燕行录》资料反映的16-19世纪东北南部地区冬半年气温变化

朝鲜古汉籍《燕行录》,是历史上朝鲜使臣出使中国的见闻记录,保留有很多历史气候资料,十分宝贵。本文收集了19种《燕行录》中记载的16-19世纪东北南部地区河流封冻情况,并利用中国其它文献为补充,使用现代河流封冻资料为对照,逐年考订了当时河流封冻与现代河流封冻的距平情况,并得出封冻期的50年平均距平值。由于冬半年气温变化是影响河流冰情的关键因素,河流封冻情况的变化可很好地反映该区域冬半年温度变化情况。分析发现,在1500-1900年间,存在3个较冷的时期,其中16世纪上半期是400年中最冷的时期;存在2个较暖的时期,分别为18世纪下半叶和19世纪下半叶。而和20世纪的温度变化衔接分析,则500年间区域气温基本是上升的趋势。同时和中国其它区域以及欧洲的小冰期温度变化序列比较,在大的趋势变化和波动方面有一致性,但在时间上并不完全一致。表明区域间气候变化的复杂性。     

历史矿区土地利用重建研究:以近代云南个旧锡矿为例

历史土地利用重建是LUCC研究的重要基础工作之一,在区域土地等资源开发及利用和环境变迁等研究中有着重要研究价值。受历史资料和数据属性局限,学界对历史上矿采用地状况及其反映的地理特征研究,量化手段和精确性不足,复原历史矿区土地利用更为少见。本文依据近世矿业档案、地理资源调查等资料,以近现代云南经济史上颇具影响的个旧锡矿为例,复原矿厂、厂尖及户数等的空间布局,重建其土地利用过程,并进一步探讨矿区人地作用相互关系的演变状况。
