2015尼泊尔地震后加德满都谷地世界文化遗产破坏特征

2015尼泊尔地震对加德满都谷地的世界文化遗产造成不可估量的损失。为了探究谷地文化遗产震害整体分布特征,对谷地世界文化遗产建筑的震害状况开展实地调查,划分了三类文化遗产震害等级标准,形成了六处世界文化遗产的震害图并对其进行统计分析,加德满都、帕坦和巴德岗三处杜巴广场震后保存基本完好的文化遗产建筑占各自总数的39.5%、53.3%、50%,斯瓦扬布纳特寺、昌谷纳拉扬寺和博达哈大佛塔主体保存基本完好,附属建筑不同程度地破坏。加德满都、帕坦和巴德岗三处杜巴广场地层的松软沉积层放大地震效应使建筑严重破坏,斯瓦扬布纳特寺、昌谷纳拉扬寺震害主要受地形特征影响。考察成果为我国同类遗产建筑的抗震防护提供参考。     

Tracing the origin of Chinese early white porcelain in the late sixth century—evidence from Xing kiln

As the criterion used by archaeologists for determining early white porcelain is quite ambiguous, the origin of Chinese white porcelain remains a point of disagreement. In this study, we systematically investigate 61 typical Xing porcelains of the late Northern dynasties to the early Sui dynasty (550–600 CE) using spectrophotometer, X-ray fluorescence (XRF), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD), and analyze the differences between early white porcelain and celadon of Xing kiln in terms of their whiteness and raw materials characteristic. The results show that early white porcelain is a new type of ware that differs from celadon, which can be distinguished by whiteness, with a whiteness greater than 8% being early white porcelain and a whiteness less than 8% being celadon. It is assumed that the ancient potters created the whiter wares based on celadon by improving the glaze and selecting new raw materials for the body, but the production of this type of ware was short lived and subsequently refined in the Sui dynasty (581–618 CE) owing to the limited improvement in whiteness.     

What do we know about the punctuated equilibrium theory in China? A systematic review and research priorities

The punctuated equilibrium theory (PET) shows that government policy is mostly stable with occasional drastic change, which scholars attribute to institutional friction and limited information processing capacity. Although the existing PET literature predominantly focuses on democracies, scholars have started to apply the theory to authoritarian countries. Autocracies are a fertile testing ground for the theory's underlying mechanisms because they appear to experience less institutional friction but more informational restrictions than democracies. However, PET studies on autocracies are still rare. To deepen our understanding of the PET and the policy process beyond democracies, we conduct a systematic review of 88 Chinese language PET journal articles. We show that Chinese language PET research is increasing. Contrary to the English language PET literature, most Chinese studies are qualitative, while a key similarity is the weak operationalization of PET core concepts. The reviewed studies confirm a punctuated equilibrium pattern of policymaking in China but provide only limited evidence for more intense punctuations compared with democracies. Future PET research on China ought to use long-term data sets and examine institutional friction and information processing by policymakers. We also argue for more international exchange and comparative research to advance our understanding of the policy process in China and other autocracies.

唐徐恽及夫人姚氏墓志考述

１９９８年在伊川县彭婆镇许营村出土的唐徐恽及夫人姚氏墓志,详述了徐恽的生平事迹,也为徐恽神道碑的所在提供了确切位置。本文就两方墓志的有关问题进行了考证。     

生境的选择与楚文化的兴起

本文借助生态学理论,对楚人的南迁过程进行了梳理,并对其迁徙原因进行了剖析。认为自楚先季连族始,开始了南迁。商代前期,其活动地域在丹江流域;商代后期,其活动地域先在丹江与汉水交汇处,后在汉水中游的方山一带;商末至西周时期,其活动地域在湖北西北的荆山一带;东周以后,其中心地域在长江与汉水之间的宜城平原和江汉平原上。迁徙有自然的原因也有人为的原因,楚文化的孕育、形成与发展则是楚人对于生境选择的结果。     

“玄奘画像”解读——特别关注其密教图像元素

西安兴教寺所存玄奘石刻像与日本现存无名氏画玄奘像,所携带的历史信息超出了图像本身。作者认为,这一源于早期行脚僧图像的出现,是由于玄奘西行求法的成功,刺激了社会民众对行脚僧的认同,加之西来传法僧的大量涌现,于是在唐末、尤其是在宋代,出现了一批行脚僧图像,并由初时的胡僧梵相,变为汉僧模样,进而附会到玄奘的图像创作上。而在日本所存著名的"玄奘画像",事实上可能是一个具密教性质的僧人图像。作者试图通过有关这一图像的文献解读,全面分析该图像所包含的历史信息。

南方地区古建筑木结构的整体性残损点指标研究

古建筑木结构的残损点指标是对古建筑木结构进行结构安全评估和加固修缮设计的重要指标,目前主要依据1992年制定的《古建筑木结构维护与加固技术规范》(GB 50165—92)中的规定,为了对该规范中的构架整体性残损点指标进行验证和补充,本研究通过对南方地区传统的穿斗木构体系和抬梁木构体系的典型榫卯节点和构架的试验研究,得出两种木构体系结构的整体性关键残损点指标,并与GB 50165—92规范进行比较分析。结果表明:规范规定的抬梁式木构架和穿斗式木构架的局部倾斜残损点比试验结果小,规范值偏于安全。规范中规定的抬梁式木构架梁柱榫卯连接残损点略小于试验结果,规范值偏于安全;而规范中规定的穿斗式木构架梁柱榫卯连接残损点对于燕尾榫穿斗木构而言是安全的,但对于透榫穿斗木构而言,则是不安全的。
