张家川马家塬战国墓地M21墓葬中铁器表面纺织残留物的鉴定

马家塬战国墓地是研究西戎文化以及秦戎文化交流的重要考古遗址。在M21墓葬发现了一些附着于铁器表面的矿化纺织品残片。这些矿物外壳保留了比较完整的纺织品形态,是研究早期纺织技术的宝贵资料。为此,本研究采用扫描电子显微镜(SEM)和高效液相色谱-质谱联用技术(HPLC-MS)对矿物纺织品残片的纤维原料进行了鉴定与分析:1)矿物外壳内部的纤维空洞结构形态与桑蚕丝的纤维形态特征相同;2)样品中检出了3组蚕丝蛋白的特征多肽片段。研究结果表明,M21墓葬中的纺织品残片的原料为蚕丝纤维(Bombyx mori)。丝绸的发现表明中原的丝绸成品或者纤维原料已经进入西戎地区,西戎与中原文明的交流更加密切。使用丝绸包裹铁器则表明西戎文化已经受到了一些中原风俗的影响。这一发现填补了马家塬遗址中纺织品研究的空白,不仅为研究秦戎地区的织造工艺和文化交流提供了重要资料,也为矿化纺织遗存中的桑蚕丝残留的鉴定提供了技术支持。     

长江三角洲技术扩散规律及其对策初探

技术扩散已经成为决定区域高新技术产业乃至区域经济可持续发展的重要因素,从时间尺度上看,区域技术扩散速度呈现\"S\"型分布。本文论述了我国经济技术较为发达的长江三角洲地区的技术扩散历程、态势、不同等级的技术扩散中心,在此基础上,提出了提高认识、建立区域技术扩散体系,发挥企业主体作用等促进技术扩散的对策建议。     

汉阳陵遗址文物保存风幕隔离及富氮低氧环境数值模拟研究

汉阳陵帝陵从葬坑遗址保护展示厅常年的高湿度环境(空气相对湿度为95%±5%)容易使遗址文物发生霉变等病害。为此本研究以从葬坑遗址保护展示厅15号坑为研究对象,根据基本假设,建立了从葬坑文物保存区域空气流动的二维数学模型,并采用标准k-ε两方程湍流模型和SIMPLE算法进行了数值计算。研究了风幕送风速度和送风仰角对风幕隔离性能的影响,并确定了15号坑适宜的送风速度为1.5m/s、送风仰角为10°。研究结果对高湿环境下如何营造风幕隔离及富氮低氧环境提供了依据,对坑式遗址文物保护具有重要意义。     

How reliable are our published archaeometric analyses? Effects of analytical techniques through time on the elemental analysis of obsidians

To assess the analytical accuracies and precisions of archaeometric elemental analyses by different techniques, a relatively homogeneous material such as obsidian must be studied. An assessment of published elemental concentration data from two Anatolian obsidian sources shows that while in most cases analytical accuracy is as high as is commonly expected, in some cases it is not. It also shows that the dispersions of elemental concentration data (indicators of analytical precisions) coming from modern analytical procedures are akin to the estimated homogeneity of the obsidian. Based on this latter observation, if one has element dispersion data from a single analytical technique, with a single source of obsidian as a control, data sets that contain multiple, but similar sources of obsidian may be differentiated.     

宋代以“重禄法”治吏惩赃政策评析

宋代熙宁年间,着力通过市易法、募役法等解决国家的财政收入问题,进而在国家行政体系的改革中推行增加吏禄、以重法治赃的"重禄法"(亦称"仓法",因首先推行自仓吏)。而市易法的收入是"重禄"的直接经济来源。实行"重禄法"以治吏惩贪,一定程度上遏制了吏的卖法弄权。由于熙宁改革的破产,重禄法难以广泛推行,并在元祐初年被名义上废止,但其以"重禄人"的形式至少推延至南宋绍兴年间;吏之有禄成为行政惯例,延续到南宋。重典治吏的思想则贯穿于宋王朝的始终。

Perceptual images of Conimbriga using High Dynamic Range

It is widely recognized that new technologies can play an important role in the interpretation of our cultural heritage legacy. This has become a powerful tool providing a better understanding of our past, and thereby, allowing us to attain a glimpse of the environments in which our ancestors lived. In this domain, the way we see such reconstructed environments is particularly important in order to establish an accurate interpretation of that historical setting. However, the desired visual accuracy in the representation of any archaeological scenario is strictly related to the technology used to visualize it. High Dynamic Range (HDR) technology encompasses the capacity to produce visual results similar to the visual acuity of the human eye, particularly in extreme lighting conditions, such as bright light or dim environments.
