略论辽三彩与唐、宋三彩的异同

唐三彩是一种流行于唐代的铅釉陶器,也是唐代陶瓷手工业的一个新品种。在中国陶瓷史上,唐三彩犹如一枝盛开的奇葩,以它那斑斓绚丽的色泽和栩栩如生的造型,赢得世人的普遍赞誉和喜爱。它与当时的诗歌、乐舞、书画、雕塑、建筑等艺术形式交相辉映,共同构成大唐盛世的豪迈雄风。继唐代之后,辽、宋时期受唐三彩的直接影响,先后烧制出了各具特色的辽三彩和宋三彩。本文通过辽三彩与唐、宋三彩的对比研究,重点探讨三者之间的共同点及相互差异。一辽国创建于公元916年,公元1125年被金所灭,共传九帝,历210年。辽与中原王朝的五代、北宋并立,以今天津…     

传统农区城乡体系空间结构演变及其形成机制研究——以河南省周口市为例

以传统农区周口市为研究对象，利用聚落斑块面积和相关社会经济指标，探讨了周口市城乡体系空间结构演变规律与作用机制。研究发现，周口市城乡体系空间结构演变呈现低端均衡结构（1973年）-点轴结构（1990年）-中心外围结构（2000年）-圈层结构（2015年）的演进过程，每种结构对城乡要素流动的方向和作用各不相同，从而使城乡体系的空间结构各不相同。交通导向机制是影响城乡体系空间结构演变的早期主导因素，促进城镇体系空间结构不断拓展，并带动乡村体系空间结构不断更迭；特色产业是影响城乡体系空间结构的新机制，助推城乡体系空间结构进一步完善；政府作用机制有效地引导城乡体系空间拓展方向，推动城乡空间格局结构性地演变。     

日本军国主义与中国劳工"万人坑"

翻开侵华日军暴行的历史,人们不难发现,侵华日军对中国人民的屠杀暴行,有两种不同的方式:     

彼得·布朗对基督教化问题的新认识

基督教在晚期罗马帝国的兴起,自爱德华·吉本《罗马帝国衰亡史》问世以来就一直是学术界关注的焦点。20世纪70年代,爱尔兰裔美国史家彼得·布朗系统地提出解释罗马帝国和古典文明命运的"晚期古代"理论。在晚期古代视角下,布朗通过文本证据与考古证据相结合,并借助后现代的"解释学的怀疑",以及"表象"理论,解构关于基督教化的传统叙事,并提出关于基督教化问题的新观点。他认为,基督教化是缓慢的不彻底的进程;是关于宇宙的集体表象的改变;具有多样性的特征。布朗的基督教化理论,更关注从多神教到基督教一神教转变过程的复杂性,注重两者的相互影响和作用,在对过程的把握中探讨文化的冲突与融合,历史的连续与断裂。     

Pollution effects of place-based policy: Evidence from China's development-zone program

Environmental externalities of place-based policy have generally been overlooked despite their welfare consequences. This paper studies the air-pollution effect of development zones in urban China using a geo-coded data set of 2720 counties from 1998 to 2016. By adopting the generalized difference-in-difference framework to resolve the problem of endogenous locational selection for place-based policies, we find that development zones reduce ambient PM_2.5 concentration by around 1.8%, leading to a total social gain of $7.75 billion USD. The environmental benefit varies by the zone's dominant industry, geographical region, administrative affiliation and time of establishment. We further show that development zones are comparably cleaner due to the incentives of central and local governments, manifested by the desire to administratively promote development zones, the attempt to satisfy residential demands for higher quality-of-life cities, and the employment of the national environmental monitoring system.     

Early use and production of iron in the northern Shaanxi: A perspective on iron objects excavated from the Yuejiazhuang cemetery site

Yuejiazhuang is a cemetery site of Qin people in the Northern Shaanxi, China, and it is dated to the mid-late Warring States Period. Ninety-two iron objects were excavated from the Yuejiazhuang cemetery site, which provide an opportunity to understand the use and production of iron in the Northern Shaanxi. The metallurgical and statistical study has revealed that bloomery iron, cast iron, and steel made from cast iron were adopted in the Northern Shaanxi during the mid-late Warring States Period. In the meanwhile, cast iron and steel made from cast iron became dominant in the Northern Shaanxi.     

High-performance enrichment of casein and ovalbumin in wall painting with immunomagnetic beads

The detection of trace binding medium in wall paintings is usually challenging due to the aging and degradation of proteinaceous binding medium in a long time. Therefore, immunomagnetic beads (IMBs) with specific enrichment ability for casein and ovalbumin were prepared, and then the beads were applied for capturing target proteinaceous binding medium from ancient Chinese wall paintings. After optimization of experimental conditions, the enrichment performance of magnetic beads was confirmed by enzyme-linked immunosorbent assay (ELISA) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). In this experiment, archaeological wall painting samples were used to verify the accuracy of the construction enrichment method. The results showed that the OD_450nm value of archaeological samples containing binding medium has increased to varying degrees after IMBs enrichment, effectively avoiding the occurrence of false negative results, indicating that the IMBs enrichment method developed in this work could be successfully applied for enriching ovalbumin and casein binding medium from ancient wall paintings for subsequently immunoassay detection.     

英藏敦煌写本《孔子家语》的初步研究

敦煌写本《孔子家语》的“十”卷并非“七”卷之误,它说明早期《孔子家语》的分卷与方法与今本不同,很可能就是二十一卷。但就文字、内容及注文来看,敦煌写本与今本基本相同,差别并不大,这说明《孔子家语》在唐以后的流传形态是基本稳定的,并不存在结构性创伤,所谓“唐本”与“宋本”的区分并没有多少实际意义。     

一门正在崛起的新学科--《海洋文化与社会》读后

从最广泛的意义上讲,文化包括人类一切的物质创造和精神创造。毫无疑义,它也包括人类一切与海洋有关的创造,就是说包括“海洋文化”。但是长期以来,人们在讨论文化问题时,往往“站在内陆而背对着海洋”,只看到陆地对于人类的生存意义,没有或者很少注意到海洋对于人类社会的重要性;只看到人类在陆地上的生产生活情况,     

从闽台动物化石看两岸亲缘关系
