Elasmosaurs (Sauropterygia,Plesiosauria) from the La Colonia Formation (Campanian–Maastrichtian), Argentina

O’Gorman, J.P., Salgado, L., Varela, J., & Parras, A., 2013. Elasmosaurs (Sauropterygia, Plesiosauria) from the La Colonia Formation (Campanian–Maastrichtian), Argentina. Alcheringa 37, 257–265. ISSN 0311-5518.

Elasmosaur postcranial remains from the La Colonia Formation (Campanian–Maastrichtian), Chubut Province, Patagonia, Argentina, are described. The new material has small dimensions and caudal vertebrae with parapophyses strongly projected laterally—characters shared with some Elasmosauridae indet. from the coeval Allen Formation, Río Negro Province, Argentina. These features reinforce the similarities between the plesiosaur faunas to the north and south of the Somún Curá Plateau. The small size of these elasmosaurs may be palaeoecologically related to the marginal marine depositional environment of the sedimentary host rocks.

读秦汉简札记四则

文中对于睡虎地秦简以及关沮秦简和张家山汉简的几个问题进行了说明,指出睡虎地秦简的"定杀"是把麻风病犯人缚以石头然后活生生地坠入水中淹死的刑罚.关沮秦简中"(羁)谋"是托人说媒的意思.睡虎地秦简中的"(埱)"字是以‘弋'掘地之义.张家山汉简<引书>的"寻"字是舒两肱的意思.     

How to Make an Unfired Clay Cooking Pot: Understanding the Technological Choices Made by Arctic Potters

Between about 500 a.d. and the late nineteenth century, clay cooking pots associated with the Thule culture were produced in the Arctic region. Ethnographic and archaeological records indicate that these vessels were typically underfired (often even unfired), highly porous, and easily broken. Despite these characteristics, the evidence indicates that they were used to heat water over open fires. In this paper, we examine how Arctic potters were able to produce unsintered vessels capable of holding liquids without disintegrating. We conclude that the application of seal oil and seal blood to the pot’s surface was the key to their success.

日本九州大宰府出土莲花纹砖浅析

日本九州大宰府出土的莲花纹砖和隋唐洛阳城出土的莲花纹砖,二者的质地、制法、功用相同,皆以莲花为主体花纹且外绕蔓草纹和联珠纹.主要差异是前者形制为长方形,莲花图案小并辅以水波纹,砖的侧面也有花纹;后者形制为方形,仅砖的正面有花纹,莲花图案肥大且没有水波纹.这表明在公元7世纪前后,中国和日本有着密切的文化交流,而日本国在吸收他国文化的同时又保持着本民族文化特征.

基于经济型酒店高速发展的背景,通过相关文献研究,选定社会经济基础、交通条件、商业因素和公共服务4大因素13项评价指标,利用综合熵权法和加权平均叠加法构建经济型酒店微观选址适宜性评价的方法和步骤,组合运用缓冲区分析以实现评价指标值计算、空间插值以实现研究区域新建经济型酒店适宜性评价、泰森多边形划分计算经济型酒店市场域以评价经济型酒店在研究区域的总体选址情况。以上海中心城区的黄浦、杨浦、虹口、长宁、徐汇、闸北、静安、普陀等8个区及区域内33家锦江之星为对象进行实证分析,结果表明：黄浦、静安以及徐汇的北部、闸北的南部适宜锦江之星选址;环城高速中延安高架路、内环高架路、中环高架路中心城区段沿线区域适宜性较高,适宜性区域沿着高架两侧分布;大部分锦江之星门店的微观选址合理。就新门店选址而言,静安和黄浦交界处、环城高速南北高架段和苏州河交界处以及黄浦区黄浦江沿岸皆为可选址区域。     

基于生活空间与活动空间视角的郊区空间研究框架

郊区空间已成为城市空间的重要组成部分,其研究意义逐渐凸显,需要学者立足郊区,关注郊区空间及其与城市空间的关系。本文从行为主义地理学和时间地理学的理论和方法论出发,对行为空间、生活空间、活动空间的概念进行辨析,提出了基于空间范式下的生活空间研究和基于人范式下的活动空间研究两方面研究内容。立足于郊区空间,面向居民日常生活,构建基于时空间行为研究方法论的郊区空间研究框架,基于此框架对郊区生活空间、郊区活动空间以及郊区空间的动态性进行解读和分析,试图为空间-行为互动理论的构建提供研究基础,为基于行为视角的郊区研究提供研究框架,为更好的理解郊区空间、解决郊区中存在的问题提供有效途径。

我国传统镁质石灰初步研究

对我国从明代到民国的建筑灰浆的化学成分、矿物成分等分析发现,部分砌筑及抹灰灰浆为镁质石灰,MgO含量达到5%~26%。特别是取自河北、北京等地长城的传统石灰样品全部为镁质石灰。镁质石灰与钙质石灰比较,具有强度高、吸水率低的特点,从而具有更佳的抗冻融性能。此外,镁质石灰收缩低、易于施工。镁质石灰煅烧需要的温度低于钙质石灰,能耗低。鉴于传统镁质石灰在中国的研究尚为空白,建议系统地开展镁质石灰研究,研究内容包括原材料类型及分布、煅烧温度、消解方式、配比优化等。同时宜研究镁质石灰在严重大气污染下的耐久性及镁质石灰相关建筑遗产的保护修复技术等。     

单檐歇山式古建筑抗震性能振动台试验

为有效保护古建筑,采用振动台试验方法,研究了中国明清官式木构古建的抗震性能。以故宫某单檐歇山木构古建为对象,制作了1∶2缩尺比例模型。模型含浮放柱底、柱架、斗拱、歇山屋顶、墙体等所有构造,且施工工艺完全符合中国明清官式木构古建施工规定。通过施加白噪声激励,获得了模型的基频和阻尼比。通过施加不同强度等级的1940年El-Centro波,获得了模型典型节点的位移和加速度响应,讨论了模型的减震系数,评价了浮放柱底、榫卯节点、斗拱、屋顶、墙体等构造的抗震性能。结果表明:模型的振动形式表现为平面内的扭摆,其原因与歇山式屋顶质量分布不均密切相关。模型的震前基频为1.47Hz,阻尼比为4.6%。地震作用下,模型的位移及加速度响应曲线近似稳定、均匀。尽管屋顶构造则对地震力有一定放大作用,但浮放柱底、榫卯节点、斗拱等构造能发挥较好的耗能减震作用。对于不同构造而言,榫卯节点的减震性能最好,其减震系数可降至0.30;斗拱次之,其减震系数可降至0.53;而浮放柱底与柱顶石之间的摩擦耗能性能最弱,其减震系数最小值为0.66。墙体在地震波强度增大过程中发生倒塌,但不影响结构整体稳定性。因此,单檐歇山式木构古建具有良好的抗震性能。
