蒋介石与1932年十九路军调闽

1931年,应粤方保障安全之请,蒋介石令十九路军调至京沪线,陈铭枢也从剿共将领成为中枢要员。自此猜忌、矛盾即在蒋与陈及十九路军之间蔓延。淞沪战事期间,由于抗战观念对立,特别是察觉陈铭枢的异志后,蒋即将陈铭枢与反叛孙中山的陈炯明划上等号,调十九路军赴闽成为必然。蒋介石档案及蒋介石日记印证了回忆录资料关于蒋调十九路军赴闽的原因,也提供了一些后者所缺失的细节。     

清宫旧藏景德镇官窑明洪武瓷研究

故宫博物院藏有传承自明代宫廷的清官旧藏洪武瓷67件,其制作工艺和装饰既有元代遗风,又有明代官窑瓷器特点,器物风格具有鲜明的由元至明过渡阶段的时代特征.结合景德镇明洪武制瓷历史背景、洪武瓷研究以及其在清宫中的原藏位置,可知清宫旧藏洪武瓷是景德镇洪武官窑受命为宫廷烧造的瓷器,反映了此时景德镇制瓷风格处于由元至明的过渡阶段,...

Impact Stiffness of the Contact-Element Models for the Pounding Analysis of Highway Bridges: Experimental Evaluation

For the requirement of pounding analysis of highway bridges, how to properly choose the impact stiffness has become a primary issue for an achieving accurate result. This article presents an evaluation test of the impact stiffness of four types of contact-element models based on the shaking table test results of a steel highway bridge model. The analytical results indicate that the theoretical impact parameters are significantly larger than the identified values because the assumptions for deriving those models cannot match the actual impact conditions. The possible reasons causing those differences are discussed at the end of this study.     

Testing the standardized growth curve (SGC) to OSL dating coastal sediments from the south Bohai Sea, China

It has been suggested that the standardized growth curve (SGC) method can be used to accurately determinate equivalent dose (D_e) and reduce measurement time. However, different opinions regarding the applicability of the SGC method exist. In this paper, we evaluated quartz OSL SGCs of marine and coastal sediments of different grain sizes and different cores in the south Bohai Sea in China, and tested their applicability to the determination of D_e values. Our results suggested as follows: (1) The SGC method is applicable to both multiple- and single-aliquot regenerative-dose (MAR and SAR) protocols of OSL dating and efficiently provides reliable estimates of D_e. (2) Finesand quartz of different palaeodoses showed highly similar dose-response curves and an SGC was developed, but old samples using the SGC method have large uncertainties. (3) For coarse-silt quartz, two different types of dose-response curves were recorded: low-dose (≤60Gy) and high-dose (≥100Gy). The growth curves of low-dose quartz were similar to each other, facilitating the use of SGC in D_e estimations, but errors tended to be larger than those obtained in the SAR method. For high-dose (100–300Gy) quartz, the SGC was also found to be reliable, but there was large uncertainty in D_e (>300Gy) estimation. We suggest that SGC could be employed for the dating of marine and coastal sediments dating using either MAR or SAR OSL protocol and either fine-silt, coarse-silt or fine-sand quartz.     

Comment on ‘Did China Import Metals from Africa in the Bronze Age?’

Lead isotope compositions provide a direct means of assessing provenance. The lead contents in bronzes cannot be used to argue against lead isotopes. Any claim for the origin of the source material for the origin of Yin‐Shang bronzes must satisfy the measured lead isotope compositions. Thus far, only southern African sources are found to meet this criteria.     

城坝遗址M45出土一组乐器的分析研究

本文对四川渠县城坝遗址出土的錞于、钲、钟一组青铜乐器做了相关分析,研究发现:这组乐器属铜锡铅三元合金,錞于、钟含有微量砷;均采用范铸法分批、分部件浇铸而成,各部位合金比例不尽相同,錞于的合金比例差别较大。通过微痕信息观察,器身上的部分巴蜀符号为刻划成型而非铸造;器物用途可能仅为陪葬品而非实用器。     

20世纪30年代全国制造工厂的区域布局——兼论后发大国工业化的空间及规模质量提升进程

1933年全国共有制造工厂4372家,分布在27个省区的391个县市,总体上呈现东部沿海制造工厂“连片发展”、中西部省区接受东部产业转移而形成的制造工厂“散点分布”的态势。这与东部和中西部的资源禀赋、交通条件、进入国际国内市场的深度和广度不同密切相关。与欧洲工业化先行国不同,20世纪前30年中国东部制造业的“连片发展”和中西部制造业的“散点分布”,不仅有赖于国际市场与国际贸易的引领和促进,更离不开国内超大市场的有力支撑,特别是后者,在一定程度上成为国内制造业应对20世纪30年代全球经济危机的“避风港”。不过,缺乏统一强大的国家政权推动的中国工业化进程,仍然面临国内超大市场启动乏力、东中西部空间隔阂、区域间的产业竞争激烈、农矿资源与资金人才市场配置不当等问题。     

浙江省博物馆藏遂安古文书

一.浙江民间文书的搜集与整理在历史研究中,民间文书作为个案资料的典型代表已经越来越受到学者重视。尤其是各地契约文书的大量发现,使契约学渐成显学。其中尤为引人注意的是徽州及闽台地区古文书研究,已形成完整体系。而近年来学者们也开始注意到浙江地区民间文书的搜集和整理研究。
