山西原平北贾铺东汉墓葬所见的北方草原文化因素——附汉鲜卑遗存的发现与辨识

2005年山西省考古研究所在原平市北贾铺村清理了东汉中晚期的7座墓葬。通过随葬陶器以及棺内铺垫石灰,死者头枕灰泥枕等埋葬习俗等因素的对比分析,发现这批墓葬的主人与当时活跃在北方草原的鲜卑集团关系密切。原平地处汉魏时期的雁门郡,是当时北方游牧集团南下侵扰比较频繁的地区,也是中原王朝安置归附的北方游牧集团部众的区域之一。结合文献记载,北贾铺东汉晚期墓葬的人群很可能属于当时归附于中原王朝的鲜卑部众,而这些率先接受了汉文化影响的鲜卑集团有可能在埋葬习俗等方面对建立北魏的拓跋鲜卑产生过一定的影响。     

旗人对八旗制度的思想态度变化

旗人对八旗制度的态度在八旗意识和八旗精神的形成中具有重要意义,它存在于八旗制度的形成、发展和完善的整个过程中,八旗制度的发展促进了旗人对八旗积极态度的形成,旗人对八旗制度的态度变化也对八旗制度的巩固和加强产生了决定性的影响.旗人对八旗制度的态度总体上经历了由服从到认同再到内化三个阶段.研究旗人对八旗制度的态度变化对目前的思想政治教育工作具有启示和借鉴作用.

Crowdsourcing Model Research for the Identification of Post-Earthquake Rescue Objects

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.     

声频应力波法检测土遗址加固用玻璃纤维锚杆锚固质量初探

土遗址锚杆锚固质量一直是土遗址加固工程中关注的重点问题。目前,土遗址领域均采用具有破坏性的拉拔试验对其进行检测。基于土遗址的文物属性,本研究尝试利用无损检测技术评价土遗址加固用玻璃纤维锚杆的锚固质量。通过锚杆无损检测仪与拉拔仪分别对甘肃省红沙堡遗址与永泰城址加固工程中的玻璃纤维锚杆锚固系统进行检测。比较实际测量杆长与仪器测量杆长结果,得出杆长指标可以判断无损检测仪所测结果的真实性。无损检测仪得出的检测波形衰减规律显著,对比相应锚杆的拉拔试验的评价结果,证实了声频应力波法在土遗址玻璃纤维锚杆锚固系统无损检测中的适用性。本研究结果将为评价土遗址加固用玻璃纤维锚杆锚固质量提供可靠的依据。     

Testing the standardized growth curve (SGC) to OSL dating coastal sediments from the south Bohai Sea, China

It has been suggested that the standardized growth curve (SGC) method can be used to accurately determinate equivalent dose (D_e) and reduce measurement time. However, different opinions regarding the applicability of the SGC method exist. In this paper, we evaluated quartz OSL SGCs of marine and coastal sediments of different grain sizes and different cores in the south Bohai Sea in China, and tested their applicability to the determination of D_e values. Our results suggested as follows: (1) The SGC method is applicable to both multiple- and single-aliquot regenerative-dose (MAR and SAR) protocols of OSL dating and efficiently provides reliable estimates of D_e. (2) Finesand quartz of different palaeodoses showed highly similar dose-response curves and an SGC was developed, but old samples using the SGC method have large uncertainties. (3) For coarse-silt quartz, two different types of dose-response curves were recorded: low-dose (≤60Gy) and high-dose (≥100Gy). The growth curves of low-dose quartz were similar to each other, facilitating the use of SGC in D_e estimations, but errors tended to be larger than those obtained in the SAR method. For high-dose (100–300Gy) quartz, the SGC was also found to be reliable, but there was large uncertainty in D_e (>300Gy) estimation. We suggest that SGC could be employed for the dating of marine and coastal sediments dating using either MAR or SAR OSL protocol and either fine-silt, coarse-silt or fine-sand quartz.     

贵在总结经验不宜急于更名——读《略论我国社会主义时期第一轮修志的时间》有感

20世纪五六十年代的新方志编纂应认真总结经验、教训.就当时修志的背景、规模、进程,尤其是从成书的数量和质量看,不宜称为"第一轮修志",可以称之为一个序幕或者一次兴起.
