洛林吉亚国王罗退尔二世离婚风波迭起的历史动因

基督教会提倡"婚姻不可分解"的理念,这种理念随着基督教会势力的壮大和宗教思想的深入人心,对中世纪西欧封建帝王的婚姻构成了一种道德约束作用。而罗马教延等现实政治生活中的各方势力也常常以此为由,向那些有违婚姻道德的世俗帝王问责发难。洛林吉亚王国的国王罗退尔二世的离婚案即是一起因此而发的政治风波。由于基督教婚姻理念的约束作用,加洛林帝国的分裂瓦解、同宗诸王的纷争内斗、教皇权威开始抬头等众多历史因素的叠加、交织,使得罗退尔二世不仅无法像他的先祖查理曼那样可以自由地离异,反而成了众矢之的,最后以"身死国灭"的历史悲剧黯然收场。     

魏晋南北朝玉佩研究

魏晋南北朝玉佩自发现以来,学术界对其性质和组构样式的判断皆不甚明了。近年南京仙鹤观东晋玉佩的完整发现,为研究其结构与性质提供了详实的研究资料。本文以此为基础,结合国内各地玉佩的发现情况及历史文献资料,分析魏晋南北朝时期玉佩发展、演变的历史原因,并试对玉佩构件进行了初步的复原研究。     

论中国古代治边思想的特点、演变和影响

古代治边思想大体形成于秦汉,发展和延续至清代,其内涵是动态变化的,经历了从肤浅到成熟的过程,各个时期的治边思想又有其特色。古代治达思想总体上有两个基本的特点：统治对开疆拓土多持相对保守的态度,认为理想的边疆治理是“守在四夷”;从“华夷有别”的治边观出发,在边疆地区施行相对宽松的羁縻统治,同时重视在边疆传播封建化的教化作用。章还以封建统治对边疆民族的治策和对边疆的经济开发为例,阐述了古代治达思想对边疆治策的广泛影响。     

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。     

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.     

古代治边观念的研究内容与主要特点

本文对古代治边观念的研究内容和主要特点进行了探讨。认为古代治边观念是中国古代逐步形成的关于边疆、历史疆域形成与管辖及相关问题的处理,在态度、方略和措施方面的一系列认识。其研究内容十分丰富,大体上包括古代边疆观、古代治边观以及对其他边疆有关问题的认识观三个主要方面。治边观念的特点主要有对历代边疆施治产生了深刻影响;与国势兴衰相关联;中原王朝与边疆政权的治边观念有一定差异;经历了发展演变的过程。     

古代"守中治边"、"守在四夷"治边思想初探

“守中治边”与“守在四夷”,是古代大多数封建王朝治边思想的核心,也是制定各项边疆治策理论的基础。在封建统治者看来,“守中”之地与“四夷”之地之间有明确的划分;大多数封建王朝所追求的理想境界,是国家的腹心地区安定繁荣,在边陲地区实现“守在四夷”。本文对“守中治边”与“守在四夷”说法的由来、内涵及其产生的影响,做了初步阐述与分析。
