关于中国古代疆域理论若干问题的再探索

本文是作者在20世纪80年代发表的有关讨论中国古代疆域的论文基础上,进一步阐述了古代中国疆域范围即古代中国统一多民族国家统一或分裂的政权所管辖疆域的观点;接着,对20世纪90年代以来有关中国疆域形成的新观点作了评述,并提出了对古代中国疆域形成、发展的阶段划分（即分期）以及规律和特征的四点认识。     

早商时期经营四土之考古学新证

早商时期,商族在推翻夏朝统治的同时,迅速据有夏的故土并极力向外开拓,夏、商两大族群及其周边各族之间的迅速渗透、融合,初步奠定了商代早期四土政治地理与民族格局的基础。     

沽源南沟村元墓与阔里吉思考

2002年,河北省文研所对沽源县南沟村俗传之辽萧太后梳妆楼进行了发掘,在祭堂内发现了一男二女的蒙古贵族墓葬,居中的男尸采用树棺葬。树棺葬的首次发现与《元史.礼乐志》等史籍所记完全相合,是考古工作的重要收获。墓葬已经过极严重的破坏,随葬品几乎全数盗失。     

唐阿史那忠镇墓石试释

1972年发现的唐阿史那忠镇墓石与其他唐墓出土的镇墓石上的文字内容有较大的差异。目前,学界对于该石上的文字内容还没有完全弄清楚。本文利用《大汉原陵秘葬经》和《地理新书》两部传世史料对阿史那忠镇墓石上的文字做进一步地释读,进而分析阿史那忠镇墓石上所反映的丧葬习俗。     

兰池都督府与兰池州

唐调露元年设六胡州,长安四年并为匡、长二州。神龙三年于此二州地设兰池都督府,分六州为县。过去学界多认为,此兰池都督府即《新唐书.地理志七》所记灵州都督府所属党项羁縻府州"兰池都督府"。本文考辨以为两兰池都督府非同一,原六胡州所设应为"兰池州"或"兰池州都督府";并考释兰池州所辖六县中,可知的有长泉县和塞门县。     

新密新砦城址中心区大型浅穴式建筑的性质再思考

河南省新密市新砦城址中心区大型浅穴式建筑并不具有古籍文献所栽"坛"、"墠"的特征,似并非当时人们用来祭祀祖先的"坛"、"墠"的遗迹.它是夏代初年夏人自然崇拜的遗迹,其具有"高而入于下"的特征,更为接近文献中所栽古人祭祀川谷泉泽之神灵的"坎".具体而论,它可能是夏代初年人们祭祀洧水之神的场所.     

从养蚕和复原织机做起

丝绸来自蚕桑丝织,蚕桑丝织的起源在本质上是一项科学技术的创造发明。先人们栽桑养蚕,并让其吐丝结茧,巧织经纬将其织成锦绮,还用印花刺绣让虚幻仙境和真实自然在织物上体现。在这一过程中,就有着无数项创造发明的专利。如把野桑蚕驯化成为家蚕,是生物学史上的一项极难的成果,     

丝绸之路与新疆古代雕塑艺术

新疆古代雕塑形式多样、内容丰富,但相关研究却相对较少。本文主要对新疆的木雕、泥塑、铜铸、金器、鹿石、石人等艺术进行了全面分析与总结,展示了新疆古代雕塑艺术的全貌。     

A Modified Capacity Spectrum Method with Direct Calculation of Seismic Intensity of Points on Capacity Curve

A direct methodology for solving the seismic intensity of each point on the capacity curve is proposed. By utilizing the procedure, a continuous curve between the structural response and the seismic intensity, the structural response function, can be easily generated. Unlike previous procedures that search for the performance point of a determined seismic intensity, the proposed methodology easily draws the full curve without iterations. The procedure is applicable to both a smooth design spectrum and an actual response spectrum. Examples indicate the methodology is accurate and fast, and convenient to be combined with existing procedures, such as Modal Pushover Analysis.     

Impact Stiffness of the Contact-Element Models for the Pounding Analysis of Highway Bridges: Experimental Evaluation

For the requirement of pounding analysis of highway bridges, how to properly choose the impact stiffness has become a primary issue for an achieving accurate result. This article presents an evaluation test of the impact stiffness of four types of contact-element models based on the shaking table test results of a steel highway bridge model. The analytical results indicate that the theoretical impact parameters are significantly larger than the identified values because the assumptions for deriving those models cannot match the actual impact conditions. The possible reasons causing those differences are discussed at the end of this study.
