吴越系青铜短剑的发现及其初步研究（图）
吴越系 青铜短剑 发现 初步研究
2011/10/19
短剑[1]是一种介于匕首与普通剑长度之间的剑型，纵观全国几个主要青铜剑系统，北方草原地区、东北和西南地区青铜短剑较为发达，发现数量较多，沿用时间也相对较长，存在于整个青铜时代。相比之下，吴越地区短剑发现较少，并且多存在于早期，而后少见。春秋战国时期的吴越系青铜剑多为统一的制式长剑，当然也不排除这一时期存在短剑的可能，但其始终不占主流。就剑体长度而言，以皖南出土的60余件周代青铜剑为例，整剑平均长度...
金元时期四种钧釉瓷器断代研究（图）
金元时期 钧釉瓷器 断代研究
2011/10/19
本文所谓四种钧釉瓷器分别为鸡心碗、罗汉碗、鸡心盘和折沿盘[1]。鸡心碗，圆口，深腹，上丰下削，小圈足；罗汉碗，直口（或微内敛），上腹壁近直，下腹壁圆折收，圈足；鸡心盘，直口，浅腹，圈足；折沿盘，折沿平口，厚唇，浅腹，圈足。这些器物在辽宁、内蒙古、吉林、河北、山西、陕西等北方省区的金元遗址中大量出土。由于大多未经正式考古发掘，缺乏用以确定具体朝代的共出物品，以致很多时候确定这些器物是金或元比较困难。...
论商周青铜器与中国人的规矩（图）
商周青铜器 青铜器纹饰 规矩
2011/10/19
商周青铜器的型体制作，靠的是原始机械造型，不是靠雕塑造型。商周青铜器的纹饰制作，靠的是几何造形，不是靠任意绘画技巧造形。在这些工艺的操作中，逐渐形成了规矩。按规矩制作出来的范就是规范，即当今“规范”一词的原型及原意。按规矩制作出的青铜器纹饰，属于规范纹饰。只要掌握规矩，虽隔千里可制作出相同的青铜器。这种按规矩操作的工艺思想，一直被延续至今，并体现在当今的各行各业之中。

At first glance, it would seem an easy task to trace the history of ecocriticism in Canada, for that history is relatively short. Indeed, it was only six years ago, in 1991, that Laurie Ricou wondered...

新砦考古的回顾与展望
新砦 考古 回顾 展望
2010/6/24
2009年适逢河南新密新砦遗址发掘30周年，30年来，新砦遗址在文化谱系、聚落形态和多学科合作方面均取得了不少重要成果，但是，展望未来，仍存在不少亟待解决的问题，需要进一步开展田野工作和各方面深入研究。本人有幸作为新砦遗址研究的直接参与者之一，在此对新砦遗址研究的历程做一简单的回顾并对今后的工作重点谈些不成熟的想法。
运城盆地区域聚落考古的阶段性成果
运城盆地 区域聚落考古 成果
2010/6/24
本课题的主要目的，是要通过聚落形态的研究，来揭示运城盆地从新石器到早期青铜时代复杂社会的形成与发展，并重点探讨龙山时代前后社会结构的特征与变化，从而确立本地区在早期国家和文明形成过程中所处的地位和所起的作用。同时也关涉到社会与环境的互动关系、重要资源的获取与利用等。
描述了产自美国北卡罗来纳州上三叠统横齿兽类北方阔齿兽新材料的牙齿。基于牙齿的特征，尤其是犬后齿的形态，这屿标本被暂归入杰斐逊北方阔齿兽Boreogomphodonjeffersoni；不过它们的下阔齿型犬后齿前横脊一般有两个而不是3个齿尖。根据牙齿大小、直接替换情况，推测阔齿型齿从后部萌发，从前部脱落。这个类群仅有一代阔齿型犬后齿；至少有一代可能是两代裂齿型犬后齿。
