中日现代化进程中观念冲突之一斑——以李鸿章与森有礼在直隶总督府的论战为中心

141年前,李鸿章和森有礼曾就日本军舰“云扬号”入侵朝鲜江华岛事件以及学习西方、变革服制、举借外债等问题在保定展开了一场激烈的论战。本文考察了森有礼于光绪元年腊月二十八日赴直隶总督府与李鸿章举行会谈的背景,并基于1899年出版的《森先生传》中揭载的对话记录,译介、分析了这场对话的主要内容;指出,尽管李鸿章组建了一个人数众多的幕府,但由于无法破除人身依附关系,未能建立独立的智库,以致他很难听到不同的意见,学到有价值的新知。因此,李鸿章与森有礼论战时无法占据明显优势也就在所难免。     

An Approach to the Diagnosis of Craniofacial Fibrous Dysplasia from the 2500‐Year‐Old Remains of a Skull from Ancient China

A human skull, buried about 2500 years ago in a Bronze Age cemetery at Jinggouzi, a site of an important ethnic group in ancient China, appeared to have characteristics of fibrous dysplasia. The CT images indicated a reduction in bone density and relatively homogeneous lesions. More features were revealed using CT reconstruction techniques. Lesions seen in low‐magnification images using a 3D deep‐field microscope had an irregular honeycomb‐like structure. At higher magnification, the trabeculae morphology and the gaps between the trabeculae were irregular and varied in size and shape. Paraffin‐embedded specimens stained with HE showed trabeculae with tortuous irregular arrangements varying in shape and width. The irregular trabeculae of woven bone has been described as having fibrous dysplasia. Molecular analysis of the GNAS gene indicated no mutation. This provides a non‐invasive approach for us to make more comprehensive diagnoses and to assist research into ancient human diseases.     

PLANTING TREES ON THE ROOF OF THE WORLD

正In China,legend says that animals choose different trees to inhabit.In Nagqu,situated on the northern area of the Tibet Autonomous Region,trees are nowhere to be seen,and birds often share holes underground with mice and rabbits.Nagqu means"black river"in Tibetan.The place is situated

Chemical and Microscopic Study of Masonry Mortar in Ancient Pagodas in East China

Ancient mortars played a crucial role in the construction of historical architectures due to their physical and chemical compatibility with traditional building materials such as stones and bricks. Therefore, the analysis and optimization of the ancient mortar formula are significant in the restoration and preservation of historical sites. In this work, 20 mortar samples selected from five ancient stone pagodas in Zhejiang Province, China, were analyzed. The results showed that mud, lime-soil mortar, lime-sand mortar, and lime-gypsum mortar were used as binders in these pagodas. The Ca(OH)₂/aggregate ratio ranging from 0.3 to 2.7 was usually used to prepare lime mortar. Protein and polysaccharide were also found in some samples.     

南诏大理国金属佛像制作工艺初探

为研究南诏大理国金属佛像的制作工艺,对部分金属佛像进行了科学分析,表明制作各种铜佛像时,主要使用失蜡铸造工艺,已使用多种金属元素作为材质,阿嵯耶观音像和其他铜像是以含砷的铜合金为特征,金质佛像的材质主要用金银合金,铸造小铜佛像则采用复杂的合金成分配比。根据铭文和绘画资料分析,这些金属佛像主要是大理本地的工匠制作。     

世界城市网络研究的热点变迁及主题判别——基于WOS数据库的知识图谱分析

借助可视化软件,从梳理研究热点及识别研究主题两方面,厘清世界城市网络的研究脉络与核心,探索未来研究动向。研究发现：①世界城市网络研究国际合作广泛,研究热点响应迅速,经历“世界城市”与“世界体系”分化阶段,网络结构聚焦阶段,城市网络的空间、地位、经济等多元阶段变迁;②研究由城市网络链接结构、全球中心城市、城市网络节点地位及城市网络经济学四大主题构成;③以往研究缺乏对网络结构绩效的研究,对非世界城市的关注不够,城市地位与经济之间的关系仍处于描述阶段;④对世界城市网络结构的内涵、非世界城市研究、整体网络与个体网络关系、经济学方向进行展望,使世界城市网络的未来研究更加全面丰富。     

Lichenometric constraints on the age of the Huashan Grottoes, East China

Lichenometry is a method of dating that has been widely used in glaciated areas for determining the minimum age of exposure of a geomorphic landform during the late Holocene. This paper presents a regional calibration data set of lichen thallus sizes versus rock surface ages for the Huashan area, East China, based on measurements of yellow-green Rhizocarpon lichens on the known-age substrates at eight sites. An empirical relationship between thallus sizes and rock surface ages was established using both the traditional regression and the Bayesian approaches. Using the Bayesian calibration, the minimum age of the Huashan Grottoes was dated from 450 ± 60 to 330 ± 60 years ago, corresponding to the late Ming Dynasty (AD 1477–1632). These dates are generally consistent with those predicted from the regression-based linear growth curve. Our results suggest that applications of this technique can be safely extended to the non-glaciated areas.
