银元主币流通与上海洋厘行市的更替

墨西哥鹰洋成为近代中国流通最广的银元主币,历时长达60余年之久。1914年后开铸的袁世凯像新币,逐渐取代鹰洋成为流通中的主币。上海钱业公所和其后的上海钱业公会深谙流通中主币的消长变化态势,审时度势,先后于1915年和1919年取消龙洋和鹰洋行市。鹰洋行市的取消进一步促使国币通行成为主币,使货币兑换市场逐步走向统一,降低社会交易成本;同时也为废两改元准备了条件,促进了近代货币统一化进程。     

《维摩演教图》及其相关问题讨论

《维摩演教图》是宋人师承李公麟的白描人物画。作者经过对比分析,认为此图不是金马云卿的《画维摩不二图》。而关于王振鹏《临马云卿画维摩不二图》也存在诸多疑问,它或许是曾经元内府收藏、清《秘殿珠林初编》著录的李公麟《画维摩不二图》卷的临摹本。     

唐代经学统一的制度性保障

《五经正义》的颁行是唐代在经学文本上的统一举措。经学思想的真正统一还有赖于制度的保障。唐代教育、科举、铨选和其他相关制度不仅确保了五经的权威,而且极大地促进了经学的全面推广和传播。这些制度为经学统一提供了源头性的保障。

Reconstructing subsistence at the Yingpanshan and Gaoshan sites in Sichuan province,China: Insights from isotope analysis on bone samples and charred crop remains

During the Neolithic period, the Chengdu Plain was a key region where two important crops, rice and millet, were cultivated together. Millet was probably introduced from north-western China c.3500–3300 cal. bce , and rice came from the Middle Yangtze River c.2600 cal. bce . In this study, human and faunal remains, as well as charred crop grains, were collected from the Yingpanshan (3300–2600 cal. bce ) and Gaoshan (2500–2000 cal. bce ) sites where the dominant crop was millet and rice, respectively. Carbon and nitrogen isotope analyses were conducted on human bones and the ecofact samples in order to reconstruct the subsistence at the sites. The results indicate that the diets of two individuals recovered from the Yingpanshan site consisted of both C₃- and C₄-based foods, predominantly the former. By contrast, Yingpanshan pigs consumed a large quantity of C₄ fodder. This result, combined with the ecofact evidence, suggests that millet was the main crop at the Yingpanshan site. It also highlights the fact that the two Yingpanshan individuals might be non-locals and/or belonged to later periods. On the other hand, the diet of the Gaoshan community was dominated by C₃-based foods. When considering the archaeobotanical evidence at Baodun, a site contemporaneous with and near to the Gaoshan site, it can be stated that rice was an important food resource for the Gaoshan community. This study also suggests how crops were managed at the two sites. The Yingpanshan people might have used manure for growing millet. Both manuring and irrigation might have also been practised by Gaoshan's rice farmers. However, more studies are required to understand the extent of manuring and irrigation in their agricultural economies.     

Some Remarks on the Origin and Chronology of Halberds in Europe

The present article examines the chronology of the various types of halberd in Europe with particular attention to those from the Iberian Peninsula. An older substrate of halberds is identified which originates in Ireland and Great Britain. From there the design of the Breaghwy type was distributed to the Continent, where the idea and the design were soon imitated in the form of the Rouans, Carrapatas and Variant 6 Continental types. The success of the idea of the halberd is explained by its high prestige character.     

NEW ARCHAEOMAGNETIC STUDIES NEAR XI'AN,CHINA*

Archaeomagnetic and mineral magnetic studies were made of known-age samples from fired structures and sediments from archaeological sites near Xi'an, China. The fired materials retained a stable record of the direction of the past geomagnetic field, which compared well with previous investigations and could contribute to an archaeomagnetic calibration curve. However, discrepancies with documented observations of the field were noted.     

Pore pressure evolution and fluid flow during visco‐elastic single‐layer buckle folding

Pore pressure and fluid flow during the deformational history of geologic structures are directly influenced by tectonic deformation events. In this contribution, 2D plane strain finite element analysis is used to study the influence of different permeability distributions on the pore pressure field and associated flow regimes during the evolution of visco‐elastic single‐layer buckle folds. The buckling‐induced fluid flow regimes indicate that flow directions and, to a lesser degree, their magnitudes vary significantly throughout the deformation and as a function of the stratigraphic permeability distribution. The modelling results suggest that the volumetric strain and the permeability distribution significantly affect the resulting flow regime at different stages of fold development. For homogeneous permeability models (k > 10^?21 m²), low strain results in a mostly pervasive fluid flow regime and is in agreement with previous studies. For larger strain conditions, fluid focusing occurs in the buckling layer towards the top of the fold hinge. For low permeabilities (<10^?21 m²), local focused flow regimes inside the buckling layer emerge throughout the deformation history. For models featuring a low‐permeability layer embedded in a high‐permeability matrix or sandwiched between high‐permeability layers, focused flow regimes inside the folded layer result throughout the deformation history, but with significant differences in the flow vectors of the surrounding layers. Fluid flow vectors induced by the fold can result in different, even reversed, directions depending on the amount of strain. In summary, fluid flow regimes during single‐layer buckling can change from pervasive to focused and fluid flow vectors can be opposite at different strain levels, that is the flow vectors change significantly through time. Thus, a complete understanding of fluid flow regimes associated with single‐layer buckle folds requires consideration of the complete deformation history of the fold.
