从三峡地区与东部平原的对比看考古学文化中的环境因素

三峡地区与东部平原的不同地理环境,导致了峡区和平原地区的考古学文化的差异。古代人类对不同地理环境适应的结果,是反映在考古学文化中的环境因素。     

高中物理新课程三维目标的教学思考

三维目标是相互联系、相互渗透的整体,是一个完整的人在物理学习探究活动中实现物理素养建构的三个侧面。因此,课堂教学应该全面关注三维目标,并将它整合于统一的物理教学活动过程之中。

Bulk element composition versus trace element composition in the reconstruction of an obsidian source system

It has become possible, through compositional analysis, to differentiate among discrete obsidian quarry and collecting localities within a single source area. The analytical potential of such information is considerable yet studies are seldom undertaken owing to the difficulties associated with trace element analysis.This study is intended to explore the feasibility of using bulk element data instead of trace element data in such compositional analyses. Techniques of bulk element analysis are far more accessible to archaeologists. The results of an experiment utilizing carefully controlled samples from the El Chayal obsidian source, Guatemala, are reported and discussed.     

Geoarchaeology and spatial distributions of the ‘Coche Quemado' obsidian source in north-western Patagonia

In north-western Patagonia, obsidian was used during the entire Holocene, and its importance increased with time. Recent fieldwork discovered a new obsidian source located in the Río Grande, which was called ‘Coche Quemado' (CQ). The results indicate that the CQ source has a different geochemical signal than all other sources in the region. Its use is spatially restricted to piedmont and, to a lesser extent, the plains. Chronologically, CQ was exploited in the middle and late Holocene, and its use accounts for a range of spatial distribution between 150 and 200 km.     

Michael Drayton’s Poly-Olbion: maritime England and the free seas debates

ABSTRACT

Attending to Poly-Olbion’s river dynamics, I argue that, implicitly opposing natural, inevitable unionization, Drayton demonstrates through visual and poetic means that any viable empire is forged by deliberate local choices about conjunction and affiliation. Further, I show that by reconfiguring Saxton’s maps, rejecting politically defined boundaries and perceptions, and situating three major rivers as the organizing features of the landscape and the empire, Drayton ultimately defines Britain as inherently and universally maritime. Moreover, linking Poly-Olbion to mare clausum and mare liberum debates, I reveal that Drayton situates the flow of self-aware rivers into the sea as an extension of Britain beyond its land boundaries. He thereby suggests that the eventual mixing of British waters with the larger oceans establishes the basis of Britain’s local and global maritime rights, linking regional autonomy and conjunction by choice with claims to both local offshore dominion and global freedom of navigation and trade.     

《史通·补注》与史注

《史通》是一部价值很高的史学理论名著,它在诸多方面为我国的史学批评开辟了道路。在《史通·补注》篇中,刘知几总结了唐朝以前史注的主要成就,划分了史注的种类。他褒扬训解式史注而贬低补阙式史注,鄙弃自注。这些观点引发了后代史学家许多争议,开创了史注研究的议题,客观上推动了史注批评的发展。     

基于曲率驱动的瓦当文字提取方法

瓦当上雕刻的篆体文字是极富研究意义的中华文化元素,为中华文字的研究提供了研究对象。本研究提出一种以曲率为基础,通过粗细两次分割实现瓦当三维文字分割的方法,解决了瓦当上雕刻文字的提取问题。首先通过计算模型表面曲率进行粗分割,并利用聚类修复方法进行细分割。由顶点曲率值衍生出的平面点集进行多平面拟合,实现瓦当表面文字的精确分割。最后应用平行细化子迭代方法进行骨架线提取,实现瓦当文字的提取。实验结果证明,文中方法可以有效地实现瓦当三维文字提取。     

论《三国史记》的编撰方法、历史观及史学思想

《三国史记》在编撰方法上借鉴了中国古代史籍的编撰体例和原则,体现曲编年体和纪传体的某些特点,同时又具有自己的编写特点;在历史观上,《三国史记》不仅体现出中国古代史籍中所具有的正统史观、天命史观以及尊儒崇礼、重民观念等史学思想,还体现了它以中原王朝为正统的史观。
