Seeking evidence: The 1984 visit to Nanjing by a Japanese investigative team and its significance

ABSTRACT

In December 1984, a private Japanese academic organization, the “Nanjing Incident Research Committee” (Nankin Jiken Chōsa Kenkyūkai), sent a survey team to visit Nanjing, with the aim of obtaining more evidence on the Nanjing Massacre to counter the internal debate within Japan. Through the coordination by the “Office of the Leading Team on History, Museums and Monuments for the Nanjing Massacre” during the visit, the survey team was able not only to gather historical materials, meet with survivors, and tour historical sites, but also to engage in exchanges with Nanjing researchers and students of Nanjing University. This visit to Nanjing further publicized Japan’s internal debate on the Nanjing Massacre in China, while also representing an unprecedented effort for collaboration between China and Japan in research on the Nanjing Massacre.     

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.     

Real-Time Dynamic Hybrid Testing Coupling Finite Element and Shaking Table

In this article, a Simulink simulation block with the finite element function is developed on the basis of S-function and implemented as the numerical substructure of real-time dynamic hybrid testing. Thereby, a real-time dynamic hybrid testing system coupling finite element calculation and shaking table testing is achieved. Using the developed system, a shear frame mounted on the soil foundation is tested, in which the shear frame is simulated as the physical model and the foundation is simulated as the finite element model with 132 degrees of freedom. Several cases of the dynamic behavior of soil-structure interaction are studied.

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.

清代纺织面料——“羽毛纱”的织物结构研究

本文运用现代纺织科学的检测手段,分析了故宫博物院收藏的两件“羽毛纱”样品的组织结构和各项物理指标（织物单位面积质量、织物密度、纱线线密度、纱线捻度和捻度系数）及其织造方法,找到了同样织法的两块织物,存在不同面料风格的真正原因。古人通过巧妙的织造方法,充分发挥纺织原料各自的优点,织造出满足不同穿着目的的面料。     

胶研水对几种传统纸张性能的影响

由明矾和胶料配制而成的胶矾水,是书画绘制、装裱和修复过程中经常使用的材料。胶矾水具有防腐、固色和增加机械力度等功能,但对纸质文物的耐久性有一定的影响。本研究选用宣纸、桑皮纸和连史纸等代表性的传统手工制纸,在它们的表面分别涂敷不同浓度的胶矾水,经干热老化后,对比分析它们的酸碱度、白度、耐折度和抗张强度的变化,揭示胶矾水对这几种手工纸张性能的影响,进而探讨其影响机理。研究结果表明,胶矾水将增加纸张的酸度、降低纸张的白度,明胶水能提升纸张的机械强度,而不同浓度明矾对纸张机械强度的影响存在差异。     

从《永泰张氏宗谱》辑录宋人佚文佚诗——兼说张元干籍贯及佚文价值

明万历年间所修<永泰张氏宗谱>,对研究南宋著名词人张元干具有重要的史料价值.二十世纪八十年代,福州市文化局的曾意丹先生和福州市文物管理委员会的官桂铨先生曾先后撰文,披露过宗谱的有关内容,曾先生撰有<张元干生平及其思想渊源考辨>①,据谱中所收张元干之子张竑墓志铭,考出张元干的卒年是绍兴三十一年(1161).官先生所撰<词人张元干世系>②,则据宗谱资料,弄清了一向混沌的张元干家世.十几年前我撰写<张元干年谱>时,主要参考的就是官先生文中提供的宗谱资料,而未能见到宗谱原书,谱中很多珍贵的资料未能采用.1989年<张元干年谱>在南京出版社出版后,我才与官先生取得联系,他慷慨地将<永泰张氏宗谱>全谱复印一份寄赠给我.我如获至宝,一直珍藏至今.
