郑韩故城热电厂墓地出土青铜器的初步分析

本文利用金相显微镜和扫描电镜能谱仪对郑韩故城热电厂墓地出土的l5件青铜器进行了分析,发现15件铜器的材质为铅锡青铜、锡青铜;制作工艺为铸造和热锻。热电厂墓地为东周时期郑韩故城贵族墓地,青铜器的初步分析研究为研究郑韩故城冶铸技术状况提供了参考资料。     

论李维的历史方法

李维的历史方法是罗马传统历史方法的继承与发展。首先,他采用了逐年纪事的年代记的叙述方式。其次,他继承了罗马史学在其肇始就具有的爱国主义偏见和为罗马辩护的特点,特别是在对史料的处理方面,他按照爱国主义和道德教导的写作目的对史料进行删选,甚至伪造。最后,李维把文学技巧应用到历史写作之中。     

从另一视角看易安词的神骏之气

李清照身为闺房女子,却有豪放的"丈夫气",反映在词的创作上,既能超越男性词的藩篱,又能超越一般女性闺秀词的局限,她的词可以用"神骏"二字来统摄,正是这"神骏"之气造就了她在中国文学史上的特殊地位。

区际综合运输通道空间结构研究——以内蒙古东部地区与东北三省为例

随着《东北地区振兴规划》的实施,由内蒙古东部地区与东北三省构成的新东北经济区区际联系不断增多,双方对功能完善的综合运输系统需求日益增强。本文采用定性与定量相结合的研究方法,通过分析区际运输通道空间结构现状及客、货流未来发展特点,遵循交通运输与区域经济发展良性互动原则,提出建设6条运输通道与15个二级运输枢纽为骨架,3条运输干线为辅助的网格状区际综合运输通道空间结构,并指出在改善铁路、公路运输方式的同时,要积极开展油气及煤化工产品的管道运输,发挥多种运输方式综合优势,促进区域协调发展。     

领导干部价值观的内涵阐释与科学创新

领导干部价值观是建立在世界观、人生观和行政价值观、政党价值观以及社会主义核心价值体系等理论基础上的。正确的领导干部价值观主要包括以人为本的理念、权为民所用的权力观、民主法治观和创新发展观。研究和分析领导干部价值观的基本内涵,树立正确的领导干部价值观,对于加强领导干部核心价值体系建设、加强和改善党的领导,具有重要意义。     

Dietary adaptation during the Longshan period in China: stable isotope analyses at Liangchengzhen (southeastern Shandong)

Rice and millet were staple crops at Liangchengzhen, a late Neolithic Longshan site in Shandong, China, but the degree of dietary variation is not known. This study uses stable isotope analysis of human and faunal skeletal remains to quantitatively address the importance of these crops as well as terrestrial domesticates and aquatic resources in the diet at Liangchengzhen. Although no collagen could be extracted from the poorly preserved human bones, the δ¹³C stable isotope results for 2 apatite sample and 16 tooth enamel samples averaged −9.8‰ suggesting that diet was based on foods averaging from −24‰ to −18‰, with millet and millet-fed animals comprising at most approximately 25–30% of the diet. Pig faunal δ¹³C isotope values suggested that during the earlier Longshan period pigs were fed mainly millet with more C₃ foods such as rice included by the later Longshan period. Solid ceramic residues from two guan jar sherds produced δ¹³C values averaging −18‰ and δ¹⁵N values averaging +16‰, suggesting both vessels contained fish. The results of the study indicate that by the Longshan period, people in southeastern Shandong no longer relied as heavily on millet and that the agricultural crop of rice had increased in importance at Liangchengzhen. Unfortunately, without human collagen samples to provide nitrogen isotope results, we cannot estimate the relative contribution of aquatic and terrestrial protein to the diet of people at Liangchengzhen. In general, however, the pattern of a diverse agricultural system on the basis of the macrobotanical remains from Liangchengzhen is supported by the isotopic results.     

中华文明的绚丽曙光--论舞阳贾湖发现的卦象文字

文章通过对舞阳贾湖遗址发现的21个刻划符号的研究,认为其构形与商周甲骨金文相似。目前已认识的11个字,分别属于反映《离》、《坤》两卦之象的卦象文字,这说明中国使用至今的汉字,早在八千多年前就产生。     

东南方言地名“干”通名释义

中国东南地区"干"通名地名分布比较密集,这些地名分为实体名+干、姓氏/人名+干、方位+干、性状+干、地名+干共五类。古代文献地名中的"干"含有"边、厓"义,可泛指边际、边缘,也可以确指水边、山麓。历史上,苏南等地的北部吴语"干"曾经也是成词语素活跃在口语中。虽然宜兴等苏南地区表示"边缘、旁边"义的"干"已经退出方言口语交际场合,只固定在地名之中,但却为研究地名通名演变,研究词语更替提供了窗口和实例。     

Nonparametric Significance Test for Discovery of Network‐Constrained Spatial Co‐Location Patterns

Spatial co‐location patterns are useful for understanding positive spatial interactions among different geographical phenomena. Existing methods for detecting spatial co‐location patterns are mostly developed based on planar space assumption; however, geographical phenomena related to human activities are strongly constrained by road networks. Although these methods can be simply modified to consider the constraints of networks by using the network distance or network partitioning scheme, user‐specified parameters or priori assumptions for determining prevalent co‐location patterns are still subjective. As a result, some co‐location patterns may be wrongly reported or omitted. Therefore, a nonparametric significance test without priori assumptions about the distributions of the spatial features is proposed in this article. Both point‐dependent and location‐dependent network‐constrained summary statistics are first utilized to model the distribution characteristics of the spatial features. Then, by using these summary statistics, a network‐constrained pattern reconstruction method is developed to construct the null model of the test, and the prevalence degree of co‐location patterns is modeled as the significance level. The significance test is evaluated using the facility points‐of‐interest data sets. Experiments and comparisons show that the significance test can effectively detect network‐constrained spatial co‐location patterns with less priori knowledge and outperforms two state‐of‐the‐art methods in excluding spurious patterns.
