古代铁器腐蚀产物的结构特征

运用X射线衍射、扫描电子显微镜和穆斯堡尔谱分析方法,对河南渑池出土的T_1H_1∶250汉代铁斧表面腐蚀物进行了研究。提出了铁器文物抗腐蚀的原因在于表面氧化膜具有结构上的连续性、改密而不破损。铁器文物最理想的保存环境应该是碱性、干燥无水、无硫、氯等有害元素。     

南京明代宝船厂遗址出土舵杆结构特征研究

南京明代宝船厂遗址的发掘及船舶构件的出土,为研究郑和下西洋活动,尤其是郑和船队的相关信息提供了宝贵的资料。宝船厂遗址中出土的舵杆是船舵的重要组成部分,也是复原船舵的主要依据。通过对舵杆本体特征部位与古代不平衡舵的比较研究,对舵首、舵身、舵尾特征部位的结构、功能进行了深入、细致的分析研究,初步完成了船舵的结构、功能和操控系统的复原。     

Ethics of heritage: locating the punitive state in the historical penal landscape of Taipei

Research into prison tourism and prison heritage has not taken enough time to understand how historical change has left impacts in urban contexts, which sometimes continues even after the prisons are decommissioned. This paper discusses the punitive state in the context of the historical penal landscape of Taipei through an exploration of how an historical prison was designed, built, partially demolished, preserved and redeveloped under three political regimes. It draws attention to the neglected relationships between punishment, colonial modernity and heritage. Drawing on the literature of dissonant heritage and dark tourism it argues that the way in which the government erased the heritage and evicted squatters without regard for colonial histories and large-scale, post-war migration is yet another way of writing imprisonment into the landscape and ‘othering’ the punished. Furthermore, in tracing the place memories, both within and outside of the high prison walls, it demonstrates the possibilities offered by ethics of heritage, with which we may counter the culture of punishment in the remaking of cities.     

Naval Battlefield Archaeology of the Lost Kublai Khan Fleets

From AD 1274 Chinese emperor Kublai Khan dispatched fleets of ships in a series of attempts to expand the empire's hegemony and extend his rule into East Asia (Japan) and Southeast Asia (Vietnam, Champa and Java). Archaeological remains associated with the fleets and battles have been found at Takashima Island, Japan and on the B?ch Ð?ng River, Vietnam. This paper develops a thematic approach to these sites within a framework of naval battlefield archaeology. It compares the similarities and differences in environmental conditions and archaeological contexts of the two sites in Japan and Vietnam. It also outlines recent archaeological research conducted between 2008 and 2010 on the physical remains at the B?ch Ð?ng River battlefield site.     

Development of Collaborative Structure Analysis (CSA) System and Its Application to Investigate Effects of Soil-Structure Interaction

In this article, a collaborative structure analysis (CSA) system is developed for integrating different finite-element simulation programs. In this system, a simulated structure is divided into multiple substructures, and the interaction between the substructures is considered. Interfaces for the commercial finite-element program ABAQUS and for an open-source framework for structure analysis, OpenSees, are developed to achieve CSA integration. The CSA system is applied to analysis of a soil-structure interaction (SSI) problem, and the effects of SSI are investigated, and the efficiency and accuracy of the system are demonstrated.     

From Revanchism to Ambivalence: The Changing Politics of Street Vending in Guangzhou

By focusing on Guangzhou's street‐vending policy transformation, this article explores how exclusionary practices of urban politics in China are undermined by those who it seeks to exclude and the progressive political climate that questions the exclusionary framework. The exclusion of street vendors in Guangzhou has been led by the National Sanitary City campaign as a revanchist project. It has been discovered that while the exclusionary strategies are rendered difficult to operate due to the resistance of street vendors who develop a flexible, individualized and small‐scale activism to maintain their livelihoods, the discourse of social harmony at national level has driven local authorities to seek alternatives expected to alleviate social resistance and address people's livelihoods. However, rather than an overturn of the punitive framework, an ambivalent approach, recognized in a recent critique of revanchism, has been adopted to mediate the tension between the needs to retain attractive city images and address the livelihoods of the poor in Chinese cities.     

钱点与“他山”景区开发

明末清初,西南变乱,为坚守名节,钱邦芑弃官退隐于贵州余庆县,开辟"他山"与"柳湖"。钱邦芑的侄儿钱点继叔父之后不遗余力地对"他山"进行开发,将荒秃的他山打造成郁郁葱葱的如画景区。并一直坚守他山故园,直至终老,其间留下许多诗作。     

THE METOK ROAD OPEN TO TRAFFIC

Metok in Nyingchi Prefecture was the only county that did not have a road in the past. On October 31st, 2013, the Road to Metok was officially opened to the public. The opening of this road signified that now all counties in China can be accessed by road.

Estimating the number of components in an OSL decay curve using the Bayesian Information Criterion

The optically stimulated luminescence (OSL) decay curve is assumed to consist of a number of first-order exponential components. Improper estimation of the number of components leads to under-or over-fitting of the curve under consideration. Hence, correct estimation of the number of components is important to accurately analyze an OSL decay curve. In this study, we investigated the possibility of using the Bayesian Information Criterion to estimate the optimal number of components in an OSL decay curve. We tested the reliability of this method using several hundred measured decay curves and three simulation scenarios. Our results demonstrate that the quality of the identification can be influenced by several factors: the measurement time and the number of channels; the variability of the decay constants; and the signal-to-noise ratios of a decaying component. The results also suggest that the Bayesian Information Criterion has great potential to estimate the number of components in an OSL decay curve with a moderate to high signal-to-noise ratio.
