赤水河疏浚与川盐(仁岸)入黔

张广泗上疏朝廷,于乾隆十年十一月至十一年闰三月,首浚赤水河,疏通68处险滩,使川盐由四川合江经赤水河到仁岸茅台村,运输路程大大缩短,盐价渐平,对黔人"斗米斤盐"之负担有所减轻,经济效益十分明显.文中还对赤水河源流及遵义知府陈玉(殿)是否参与赤水河疏浚、吴登举之死等问题,均有论述与考辨.     

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。     

First Evidence Of The Use Of Freshwater Pearls As A Cosmetic In Ancient China: Analysis Of White Makeup Powder From A Northern Song Dynasty Lv Tomb (Lantian,Shaanxi Province,China)

The Lv family tombs in Lantian, Shaanxi Province are one of the most important archaeological sites of China in recent years, providing numerous objects and a wealth of information for the study of the history of the Northern Song dynasty. There were a large number of exquisite cultural relics unearthed from the tombs, including one porcelain box containing white powder, which was identified as women's makeup. The phase composition, microstructure, thermal properties and characteristics of the trace elements in the unearthed white cosmetic powder were comprehensively analysed by X‐ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry – thermogravimetry (DSC–TG), Fourier transform infrared (FT–IR) microscopy and inductively coupled plasma atomic emission spectroscopy (ICP–AES). The white makeup powder was determined to be a product made from high‐quality freshwater pearls. These results, for the first time, showed evidence that freshwater pearl powder was used as a cosmetic in ancient China using archaeological objects, providing scientific evidence and new clues to enrich and expand research into the ancient Chinese cosmetic materials.     

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.

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.     

丽江古城空心化现象治理研究

纳西居民是丽江古城的魂。随着丽江旅游的发展,近年来纳西居民纷纷外迁新城．古城空心化现象严重地危及了古城的可持续发展。纳西居民选择留下来的机会成本远高于现实收益．这是居民外迁的原因。政府应当根据古城空心化现象的成因来构建相应对策。
