在简述物流发展背景与研究现状的基础上,作者界定了物流网络的概念与研究地域的范围,并且分析了环渤海物流网络的构成。同时作者仔细探讨了环渤海物流网络的形成机制和运作模式,通过分析,作者认为网络轮廓-海陆地域形状、网络节点-城市、网络联线-运输通道、网络能量-区域经济和运作主体-物流企业等五个要素共同作用而形成了物流网络,其运作由运作模块、驱动模块和调控模块组成。最后作者提出了相应的发展对策。     

金沙遗址博物馆大气污染特征研究

为全面了解金沙遗址博物馆遗址区空气污染特征及污染物来源,在2019年秋季对遗址保护厅内外大气中细颗粒物(PM_2.5)和挥发性有机物(VOCs)进行了观测,并对各自化学组分进行了全面分析。结果发现:金沙遗址博物馆遗址保护厅内外PM_2.5污染严重,平均质量浓度分别为77.0μg/m³和94.6μg/m³;受人为影响程度的不同,室内昼夜差异明显强于室外。室外的OM、NO₃^-和SO₄^2-浓度高于室内,而室内的NH+4和典型的地壳元素(K⁺、Mg²⁺和Ca²⁺)浓度高于室外;受化学组成的影响,室内外PM_2.5分别呈碱性和酸性。地壳元素在整体元素中占据绝对主导,室内外占比分别可达82.8%和84.4%。通过富集因子分析得知Cu(室外)、Ag、Cd、Sb元素均达到了重度富集。室内外VOCs浓度几乎相同,分别为81.2×10^-9和81.3×10^-9,其中烷烃的贡献比例最高,分别为44%和46%;源自机动车、工业溶剂涂料使用、燃油挥发及生物质燃烧等人为源的VOCs物质在室外的浓度要明显高于室内。这些研究结果对于金沙遗址博物馆遗址区空气质量的全面了解、土遗址及其中文物的高质量保存和提供优质的参观环境具有重要意义。     

安徽南陵出土部分青铜器研究

安徽省南陵县是长江下游地区最早而且规模最大的冶炼中心之一,其古代矿冶遗址可上溯至西周晚期。本研究对南陵出土的不同年代和类别的青铜器样品进行了金相检测及合金成分定量分析。结果表明,只有容器存在铜铅二元合金和铜锡铅三元合金,但是热锻淬火的容器却不含铅,含锡量恰好位于适合该工艺操作并具有良好性能的区间。兵器、工具、车马饰均为铜锡二元合金,说明当时的工匠对于合金成分配比与性能的关系有明确的认识。越式鼎腹部样品具有热锻淬火马氏体组织,同样的金属结构还见于汉代铜锣等乐器、峡江地区战国中晚期青铜剑、江都大桥镇南朝青铜器窖藏出土的多件青铜容器,而镇江地区出土吴国青铜戈则具有铸造淬火组织,工艺稍有差别。这些器物中发现高锡青铜淬火组织不是偶然的,高锡青铜热锻淬火技术至少可以上溯至春秋战国时期,用以改善高锡青铜的机械性能。     

清代官窑瓷器的透明釉成分分析研究

清代官窑瓷器元素成分数据库建立工作,是上海博物馆古陶瓷科技分析研究中的一个重要组成部分。本项工作以清代官窑瓷器的透明釉为主要研究对象,应用无损的X荧光检测设备和定量分析方法,分析了多种类别瓷器中透明釉的成分配比,涉及到的清代官窑瓷器品种主要包括青花、白釉、釉里红、高温颜色釉、粉彩等。主要包含有清代官窑瓷器中透明釉元素成分分布特征、样品分类、完整器成分分析特点等方面的内容和讨论,通过清代官窑瓷器中元素含量的变化情况,给出清代官窑瓷器的元素成分数据库相关信息,同时结合古文献记载,探讨清代官窑瓷器制作的有关规律。     

19世纪中国外销油画的白色颜料研究——以《上海外滩》油画为例

外销油画(export oil painting)作为中国早期油画遗存,不仅呈现了中国南方沿岸城市的地理风貌和风土民俗,而且蕴藏着中国早期本土油画的制作技艺。本研究采用X射线荧光光谱、扫描电子显微镜-能谱,并结合傅里叶变换显微红外光谱和拉曼光谱调查了一幅19世纪中国外销油画《上海外滩》中所用白色颜料的种类及其使用方法。研究结果表明:该幅清代油画画作底子所使用的白色颜料主要为白垩(CaCO₃)和石英(SiO₂);在颜料层中发现含锌颜料与油性媒介发生化学反应的产物羧酸锌(金属皂)。本研究为中国早期外销油画的材料与技法研究及修复保护提供了参考依据。     

青海大通县出土汉代玻璃的研究

本文共对12件玻璃样品进行化学组成分析.其中,部分样品还进行了密度测定,X 射线衍射分析和显微镜观察.此外,还对一颗黄色玻璃珠的表面层进行 SEM-EDX 分析.结果表明,该玻璃珠表面有金箔涂层.根据分析结果,青海大通县出土玻璃的基础成分可归为三类,即铅钡玻璃(Na_2O-PbO-BaO-SiO_2系统玻璃),钠钙玻璃和钾硅玻璃(K_2O-SiO_2系统)。此外,还对玻璃的来源进行了探讨.     

Statistical methodology in numismatic studies

The note is concerned with the statistical methods applied to numismatic studies with particular reference to a previously published study of the trace-element composition of Augustan coins (Carter, G. F. (1978), Journal of Archaeological Science5). In particular, it is shown that the grouping procedure proposed by Carter is likely to produce too many “significant” groups. The compositional differences between predefined groups based on issue and year of manufacture are also considered. Multivariate techniques are used to investigate these differences and the advantages of this approach in comparison to the inspection of univariate plots are pointed out.     

Crop Fertility Conditions in North-Eastern Gaul During the La Tène and Roman Periods: A Combined Stable Isotope Analysis of Archaeobotanical and Archaeozoological Remains

ABSTRACT

Considerable archaeobotanical datasets describe cereal cultivation in north-eastern France, from the Iron Age to the Roman period. This study aims to complement these by using stable isotope analysis on charred cereal grains. Soil fertility was investigated through δ¹⁵N and δ¹³C analyses of 1480 charred cereal grains, dated from the Late La Tène to the Late Antiquity periods. In the Île-de-France, charred grain Δ¹³C values suggested good hydric conditions, with drier episodes in the 1st and 3rd century AD; while in Champagne, the lower Δ¹³C values for spelt reflect the lower water holding capacity of the chalky soils. A wide range of cereal δ¹⁵N values (0.8–8.7‰) implies a wide range of soil fertility conditions. Jouars-Pontchartrain and Palaiseau (Île-de-France) yielded the highest cereal δ¹⁵N values, whereas Acy-Romance (Champagne) delivered among the lowest. From these three sites, the δ¹⁵N values of red deer bone collagen were used to estimate the reference δ¹⁵N values for unmanured plants. Unlike in Acy-Romance, there were significant differences in Palaiseau and Jouars-Pontchartrain, indicating that the cultivated cereals inherited their high δ¹⁵N values from manured soil. At Jouars-Pontchartrain, the δ¹⁵N value (almost 9‰) suggested a high trophic level manuring source, possibly from pig and/or human faeces.     

‘Where the F… is Vuotso?’: heritage of Second World War forced movement and destruction in a Sámi reindeer herding community in Finnish Lapland

In this paper we discuss the heritage of the WWII evacuation and the so-called ‘burning of Lapland’ within a Sámi reindeer herding community, and assess how these wartime experiences have moulded, and continue to mould, the ways people memorialise and engage with the WWII material remains. Our focus is on the village of Vuotso, which is home to the southernmost Sámi community in Finland. The Nazi German troops established a large military base there in 1941, and the Germans and the villagers lived as close neighbours for several years. In 1944 the villagers were evacuated before the outbreak of the Finno-German ‘Lapland War’ of 1944–1945, in which the German troops annihilated their military installations and the civilian infrastructure. Today the ruins of demolished German military installations persist around the village as vivid reminders, and act for the villagers as important active agents in memorising this vital phase in Lapland’s recent past. They also appear to facilitate nostalgia for the more independent days before traditional Sámi lifeways were ruptured by stronger Finnish State intervention in the post-war decades.     

High‐boron and High‐alumina Middle Byzantine (10th–12th Century ce) Glass Bracelets: A Western Anatolian Glass Industry

The trace element boron is present in most ancient glasses as an impurity, and high boron (≥ 300 ppm) marks raw material sources that are geologically specific and relatively uncommon. Recent analyses of Byzantine glass with high boron contents suggest that glass‐making was not limited to the traditional regions of the Levant and Egypt, and a production origin in or near western Anatolia is proposed. Glass bracelets from ?i?n al‐Tīnāt in southern Turkey give fresh evidence for the production and circulation of high‐boron glasses that closely correlates with object typology. The patterning of findspots suggests that high‐boron glass was closely connected to the Byzantine world.
