进身无阶悲剧心态下的自我放逐——论乔吉散曲中的儒道思想

乔吉散曲中有积极入世的儒士思想,又有消极避世的隐士情怀。这两种矛盾思想在他作品中的交替出现,既是元代后期动荡社会在他心理上的投影,也是他宣泄感情的一种方式。在文化论争朝向多样化的今天,乔吉作品中的儒道思想分析有助于我们更全面的了解其人其作。     

EPISODIC SUSPENDED SEDIMENT TRANSPORT AND ELEVATED POLYCYCLIC AROMATIC HYDROCARBON CONCENTRATIONS IN A SMALL,MOUNTAINOUS RIVER IN COASTAL CALIFORNIA

Suspended sediment and organic contaminants were measured during a period of 2 years in the San Lorenzo River, central California, which discharges into the Pacific Ocean within the Monterey Bay National Marine Sanctuary, in an effort to quantify the potential environmental effects of storm events from a steep, mountainous coastal urban watershed. Most suspended sediment transport occurred during flooding caused by winter storms; 56% of the total sediment load for the 2‐year study was transported by the river during one storm event in January 2010. Concentrations of polycyclic aromatic hydrocarbons can exceed regulatory criteria during high‐flow events in the San Lorenzo River, and total annual polycyclic aromatic hydrocarbon load was on the order of 10 kg in water year 2010. These results highlight the importance of episodic sediment and contaminant transport in steep, mountainous coastal watersheds and emphasize the importance of understanding physical processes and quantifying chemical constituents in discharge from coastal watersheds on event‐scale terms.

三峡库区中咀坡大坝筑坝材料碾压试验

后溪河水电站中咀坡大坝为混凝土面板堆石坝,在填筑前进行了大型碾压试验。针对不同填筑区筑坝材料的铺料厚度、铺料方式、碾压遍数、碾压速度、加水量等施工参数进行碾压试验,在获得大量真实有效试验数据的基础上,运用数理统计和EXCEL图表分析法对试验数据进行了综合分析,据此确定合理的施工参数。通过对碾压试验资料的分析提出了合理的填筑施工参数及质量控制指标,并且该工程的碾压试验结果也可为同类工程建设参考。     

郑玄《诗经》笺及《三礼》注疑问句的研究

郑玄为《诗经》《三礼》所作笺注中的疑问句,反映了东汉末期疑问句的特点。从郑注看,其疑问句中的疑问词出现了双音化现象,疑问标记三重复用现象也有所增多,疑问代词"何"也成为了较高层级的疑问标记。     

Built Conservation and the Unfinished Fabrics of Time

Differentiating between the static impulse to preserve and the more open-ended and imaginative process of conservation, Federica Goffi presents a building as ‘a fabric that, even when complete, is unfinished and open to change’. Associate Professor and Associate Director of Graduate Programs at the Azrieli School of Architecture and Urbanism at Carleton University in Ottawa, Goffi has written widely on the topic of time, particularly taking St Peter's in the Vatican by way of example.     

Renzo Piano: Poet of Technology

The architecture of the Renzo Piano Building Workshop (RPBW) is renowned internationally for the formal refinement of its components and detailing as well as for its sensitive responses to context, both in terms of its physical surroundings and local construction traditions. But, as architectural author and Piano specialist Peter Buchanan reminds us, the central concern of the practice remains focused on the original core impetus of expandingthe bounds of what technology and materials can achieve.     

南北朝至隋唐时期佛教寺院经楼、钟楼布局变化初探

在佛教寺院中的经楼与钟楼是早期佛寺的重要布局要素之一.但是,由于中国早期佛教考古发掘资料的缺乏,我们尚不知道其具体布局情况如何.因此,该文基于南北朝至隋唐时期的有关佛教文献记载,以及敦煌莫高窟佛寺壁画和韩日早期佛寺遗址资料,南北朝至隋唐时期佛寺中的经楼与钟楼布局变化进行整理分析,得到如下结论：由南北朝至隋唐时期,在佛寺布局中的经楼与钟楼,由佛殿后边至佛殿前边、由中心院落以外至中心院落以内迁移,但其左右位置却无定制.     

大型城市遗址的保护与展示——以隋唐洛阳城的实践为例

介绍隋唐城遗址的保护展示实践,设计将隋唐城宫城遗址的保护展示视为保护遗址、传达文物信息、表达城市历史格局变迁、重组城市风貌的综合性工作,在本体保护与文化传承相结合、专业保护与回馈社会相结合、文物保护与名城保护相结合等领域作出了探索.
