太平洋战争时期在渝韩国独立运动团体与苏联

抗战时期在渝韩国独立运动团体与苏联的关系,以前少为人知。最近,笔者在俄罗斯外交部档案馆发现了4封韩国独立运动团体写给斯大林的信函。这4封首次批露的信函对初步了解当时韩国独立运动与苏联的关系以及韩国独立运动阵营的处境,有一定参考价值。

银雀山汉简《定心固气》与孟子思想

银雀山汉简《定心固气》篇现存简十三枚,残损较多。文中有"积气"、"守一"、"定心"、"固气"、"独行"等内容,是一篇专论养气修性的古代文献,是研究传统文化的珍贵资料。《孟子》中也曾讨论"知言养气"的理论,其说与简文相近。

A New Proposed Passive Mega-Sub Controlled Structure and Response Control

It is still a serious challenge for structural engineers to effectively reduce the seismic responses of tall and super tall buildings to further improve these structural safeties. In order to solve this problem, in this article a new kind of structural configuration, named passive mega-sub controlled structure (PMSCS), is presented, which is constructed by applying the structural control principle into structural configuration itself, to form a new structure with obvious response self-control ability, instead of employing the conventional method. In the analysis of PMSCS the equations of motion of the seismically excited system are developed, based on a realistic analytical model of the complete mega-structural system. Expressions of the displacement and acceleration response of the structure, resulting from simulated earthquake ground motions represented by stationary and nonstationary random processes, are derived. These responses are then determined for both the PMSCS and its conventional mega-sub structure (MSS) counterpart, whose configuration was modeled after the traditional mega-frame that was used in the construction of the Tokyo City Hall. A parametric study of the structural characteristics that influence the response control effectiveness of the PMSCS is presented and discussed. The region over which these structural characteristics yield the optimum seismic response control of the PMSCS is identified and serves as a very useful design tool for practitioners. The study illustrates that the proposed PMSCS offers an effective means of controlling the seismic displacement and acceleration response of tall/super-tall mega-systems. It also overcomes shortcomings exhibited in earlier proposed mega-sub controlled structural configurations.     

Dynamic Characteristic Analysis of Two Adjacent Multi-grid Composite Wall Structures with a Seismic Joint by a Bayesian Approach

Field ambient vibration tests and modal identification using a Bayesian approach are conducted for a building made of multi-grid composite wall structure and divided into two adjacent parts by a seismic joint, to investigate the dynamic characteristics of the special structural type and the effects of the infilled seismic joint. It is found that dynamic interactions between the two structural parts exist possibly induced by the infill of the building separation. Natural frequencies obtained from other two modal parameter identification methods and modal analysis results of finite element models considering dynamic interactions agree with those identified by the Bayesian approach.

‘Cloths with Names’: Luxury Textile Imports in Eastern Africa,c. 1800–1885

In the nineteenth century, a vast area of eastern Africa stretching the length of the coast and into the reaches of the Congo River was connected by long-distance trade mostly channelled through the Omani commercial empire based in Zanzibar. As studies have recently shown, a critical factor driving trade in this zone was local demand for foreign cloth; from the 1830s the majority of it was industrially made coarse cotton sheeting from Europe and America, which largely displaced the handwoven Indian originals. Employing archival, object, image and field research, this article demonstrates that until 1885 luxury textiles were as important to economic and social life in central eastern Africa, textiles known to the Swahili as ‘cloths with names’. It identifies the thirty or so varieties which élites — and, increasingly, the general population — selected for status dress and gifts, instrumental in building the commercial and socio-political networks that linked the great region. Finally, it shows that the production and procurement of most varieties remained in the hands of Asian textile artisans and merchants; most prestigious and costly were striped cotton and silk textiles handcrafted in western India, and in the southern Arabian nation of Oman. European industrial attempts to imitate them were hampered by several factors, including their inability to recreate the physical features that defined luxury fabrics in this region — costly materials, rich colours, complex designs and handwoven structures.     

卜辞所见商代宗教哲学中的“命”

殷墟卜辞中有“帝于令”,“令”指“天命”。卜辞中又有“受命”,即文献中所说的“正命”,或“考终命”。卜辞中有“不既赢”,“赢”读为“盈”,指乾阳之气,如同文献中所说的“休命”。《甲骨文合集》6928是一版武丁时代的龟腹甲,上有“帝命”,反映了古代天人相应的观念。
