This paper provides a new review of archaeometric research carried out on glass found in China, set in an archaeological context, from its earliest occurrence to the Song dynasty. It is set within a broad geographical context taking the terrestrial and maritime Silk Road contacts into account. We discuss chemical and isotopic compositional contrasts in glasses from different periods found in different parts of China, the glasses that were almost certainly made in China and those that were imported. A theme that runs through the paper is the problem of provenancing glass found in China, along with a lack of evidence for primary glass‐making sites and minimal evidence for secondary glass production. We discuss the glass artefacts that are of typical Chinese types and contrast these with imports; the structure reflects this contrast. We discuss potential new scientific and archaeological approaches to Chinese glass. 相似文献

Pan, Z., Zhu, M., Zhu, Y. &; Jia, L., August 2017. A new antiarch placoderm from the Emsian (Early Devonian) of Wuding, Yunnan, China. Alcheringa 42, 10–21. ISSN 0311-5518.Wufengshania magniforaminis, a new genus and species of the Euantiarcha (Placodermi: Antiarcha), is described from the late Emsian (Early Devonian) of Wuding, Yunnan, southwestern China. The referred specimens were three-dimensionally preserved in black shales, allowing a high-resolution computed tomography reconstruction of anatomical details. The new euantiarch is characterized by a large orbital fenestra, an arched exoskeletal band around the orbital fenestra and a developed obtected nuchal area of the skull roof. Maximum parsimony analysis, using a revised data-set of antiarchs with 44 taxa and 66 characters, resolves Wufengshania gen. nov. as a member of the Bothriolepididae, which is characterized by the presence of the infraorbital sensory canal diverging on the lateral plate, and the nuchal plate with orbital facets. New analysis supports a sister group relationship between Dianolepis and the Bothriolepididae. Luquanolepis, a coeval euantiarch from the neighboring site of the new form, is referred to the Asterolepidoidei and represents the basalmost and earliest member of the Asterolepidoidei.Zhaohui Pan* [panzhaohui@ivpp. ac. cn], Min Zhu* [zhumin@ivpp. ac. cn], You’an Zhu?

为了探讨多光谱摄影技术在纺织品文物信息无损提取中的实用性,利用多光谱成像系统和微型光谱仪对正德八年诰命中破损的纹理组织、模糊的墨书字迹进行识别。在对诰命的图像信息提取后发现,多光谱的红外光波段对纺织品文物上的墨书字迹具有较好的识别作用;在颜色复杂或肉眼无法识别细微纹理的情况下,结合提取对象的反射光谱,可以较好获取织物颜色和纹理信息,完善和补充纺织品文物的相关信息。多光谱摄影技术在纺织品文物信息无损分析方面具有较好的实用性。 相似文献

Latent trajectory models for space‐time analysis: An application in deciphering spatial panel data 下载免费PDF全文

This article introduces latent trajectory models (LTMs), an approach often employed in social sciences to handle longitudinal data, to the arena of GIScience, particularly space‐time analysis. Using the space‐time data collected at county level for the whole United States through webpage search on the keyword “climate change,” we show that LTMs, when combined with eigenvector filtering of spatial dependence in data, are very useful in unveiling temporal trends hidden in such data: the webpage‐data derived popularity measure for climate change has been increasing from December 2011 to March 2013, but the increase rate has been slowing down. In addition, LTMs help reveal potential mechanisms behind observed space‐time trajectories through linking the webpage‐data derived popularity measure about climate change to a set of socio‐demographic covariates. Our analysis shows that controlling for population density, greater drought exposure, higher percent of people who are 16 years old or above, and higher household income are positively predictive of the trajectory slopes. Higher percentages of Republicans and number of hot days in summer are negatively related to the trajectory slopes. Implications of these results are examined, concluding with consideration of the potential utility of LTMs in space‐time analysis and more generally in GIScience. 相似文献

A new artwork trading model emerged in China at the beginning of 2010s: the value of a piece of artwork was divided into equal shares, and investors could buy and sell these shares in the cultural artwork exchanges, in exactly the same way as investors trading stocks in the stock market. In China, this trading model, once available, was hotly pursued by investors. This rapid market growth quickly descended into trading market confusion and speculation, forcing the government to deal with this model and eventually putting a stop to it. In this paper, we take a closer look at the reasons for the artwork shares’ price booming and slumping, the disorder and speculation in the artwork share trading market, and the reasons why the Chinese government halted this kind of trade. Taking the Tianjin Cultural Artwork Exchange of China as an example, we found that artwork can be an alternative investment vehicle, but the share trading model, similar in function to the stocks and bonds market, is not fit for artwork. The lack of legal basis and supervision by governmental bodies, together with the changeable trading rules has also contributed to the failure of this artwork trading model in China. 相似文献
