故宫建福宫石质文物保存状况的评价研究

故宫建福宫遗存了大量石质构件,其风化现象比较严重。为评价其保存状况,对建福宫石质构件的划痕宽度、回弹性能、自由渗水率、表层波速与透射波速进行取点测试,与新鲜石材数据对比后,证实其风化程度比较严重,需要进行后续的保护处理。同时还对影响建福宫石质构件风化的环境因素进行测试分析,研究了环境因素与石质构件保存状况的关系,为病害分析乃至保护操作提供了数据及理论支持。     

历史时期大清河南系的变迁研究——兼谈与白洋淀湖群的演变关系

海河水系以"清"为名的大清河其实只是相对于位居其南、其北著名浊流滹沱河与永定河而言的"清"河。历史时期,随着上游水土流失的日益加剧,大清河南系各河含沙量不断增高,干流段决徙逐渐频繁。本文利用历史文献,对先秦以来在自然与人类活动共同影响下的大清河南系的变迁进行了探讨,揭示和总结了两千余年来水系格局变动的基本过程及主要特点。大清河南系又是白洋淀湖群地表径流补给最大的水源,上述研究结论还将是理解和分析这一著名湖群演变不可忽视的重要基础。     

Late Silurian trace fossils from the Melbourne Formation,Studley Park,Victoria, southeastern Australia

An ichnoassemblage of 10 ichnospecies is described for the first time from the Late Silurian Melbourne Formation at Studley Park, Victoria, southeastern Australia. The ichnofauna is preserved in a typical deep-water turbidite succession of alternating thin- to thick-bedded sandstone and thin- to medium-bedded mudrocks. Trace fossils observed within the study site have been assigned to three main ichnofacies. Ichnofacies 1 is best developed on the linguoid-rippled upper surface of thin sandstone beds and includes Laevicyclus, Aulichnites, Nereites, Helminthoidichnites, small Chondrites and possible Zoophycos. Ichnofacies 2 is very similar to Ichnofacies 1 in ichnospecies composition but instead contains large forms of Chondrites together with other thin burrow types usually poorly preserved and in very low abundance compared with Ichnofacies 1. Ichnofacies 3 is preserved mainly as casts on the underside of medium- to thick-bedded turbiditic sandstones, and has a very low diversity, with Planolites being the most common trace. A detailed analysis of the ichnofabrics and tiering structures of these ichnofacies suggest that Ichnofacies 1 and 3 represent ‘simple tiering’, in contrast to Ichnofacies 2, which is more characteristic of ‘complex tiering’. Despite the differences in ichnospecies composition and ichnofabrics between the three recognized ichnofacies, the collective ichnoassemblage from the study site can be assigned confidently to the Nereites ichnofacies and is, therefore, interpreted to have formed in a distal submarine fan environment of lower bathyal to abyssal depth. Further, it is possible to recognize two main subenvironments within this deep-sea setting to account for the differences between the ichnofacies. Ichnofacies 1 and 2 are interpreted to represent a typical Nereites ichnofacies located on a level basin floor subenvironment of relatively low energy conditions at the distal end of a submarine fan deposit. In comparison, Ichnofacies 3 is dominated by Planolites with rare other facies-crossing trace fossil forms, and lacks Nereites. It is, therefore, best interpreted as representing a relatively high-energy environment, possibly a distributary channel near the distal end of the submarine fan system.     

A new Changhsingian (Late Permian) brachiopod fauna from the Zhongzhai section (South China) Part 3: Productida

Zhang, Y., He, W.H., Shi, G.R., Zhang, K.X. & Wu, H.T., 26.2.2015. A new Changhsingian (Late Permian) brachiopod fauna from the Zhongzhai section (South China) Part 3: Productida. Alcheringa 39, xxx–xxx. ISSN 0311-5518.

As the third and last part of a systematic palaeontological study of the brachiopod fauna from the Permian–Triassic boundary section at Zhongzhai in Guizhou Province (South China), this paper reports 15 species (including three new species: Tethyochonetes minor sp. nov., Neochonetes (Zhongyingia) transversa sp. nov., Paryphella acutula sp. nov.) in Order Productida. In addition, the morphological features and definitions of several key Changhsingian brachiopod taxa (e.g., Paryphella and Oldhamina interrupta) are clarified and revised.

中国古代之“冲”小考——兼论汉景帝阳陵出土“攻城破门器”的命名

冲是我国古代重要的攻守器具,先秦时代已经出现,文献如<诗经>、<墨子>以及后世兵书多有记载.古代之冲可分两种,一种是作为攻城器具之冲,即冲车;一种是作为守城器具之冲,秦汉以前文献称作"飞冲".两种冲之功用都是凭借冲槌的冲击力撞击敌方城墙、城门或者其它设施,故有的文献又称其为"撞车"[1].

我国党政关系规范化的必然性及其实现途径

党政关系是现代国家政治生活中最基本的政治关系。在我国,党政关系先后历经了＂寓党于政＂、＂以党代政＂、＂党政分开＂以及＂党政关系规范化＂四个阶段。历史发展的进程告诉我们,党政关系规范化是正确处理党政关系的必然选择。因此,加强党的领导,积极发挥人大的作用,实现党政关系的法治化,建立党政信息公开机制,都将有助于实现党政关系的规范化。     

青海农村少数民族贫困妇女文化教育救助调查与分析

近年来,青海农村少数民族贫困妇女对子女的文化教育、家庭饮食和医疗保健的认识有了一定的提高,但是自觉脱贫的意识较差,还存在对文化教育重视不够等诸多问题。解决这些问题,既要不断提高广大少数民族妇女学习和掌握文化技能的主动性、积极性,激发她们内在的潜能,也要通过政府和社会的有效宣传以及引导和扶持,使少数民族贫困妇女实现真正意义上的脱贫致富。
