本文在整理原件的基礎上考證了陝西省神德寺塔出土文獻Y0001號寫經卷子,證明這件以往被鑑定爲"元明時期"、"金元時期"的作品其實是唐人寫經;因其避唐太宗李世民諱而"民"字缺筆,故其書寫的時間上限是唐太宗李世民登位的貞觀元年(627),下限是五代後周恭帝顯德七年(960);因其不避唐高宗李治諱而直書"治"字,故其準確書寫時間可有幾種不同的推測。 相似文献

Elastomeric pad bearings are widely applied in short- to medium-span girder bridges in China, with the superstructure restrained by reinforced concrete (RC) shear keys in the transverse direction. Field investigations after the 2008 Wenchuan earthquake reveal that bearing systems had suffered the most serious damage, such as span falling, bearing displaced, and shear key failure, while the piers and foundations underwent minor damage. As part of a major study on damage mechanism and displacement control method for short- to medium-span bridges suffered in Wenchuan earthquake, a 1:4 scale, two-span bridge model supported on elastomeric pad bearings were recently tested on shake tables at Tongji University, Shanghai. The bridge model was subjected to increasing levels of four seismic excitations possessing different spectral characteristics. Two restraint systems with and without the restraint of RC shear keys were tested. A comprehensive analytical modeling of the test systems was also performed using OpenSees. The experimental results confirmed that for the typical bridges on elastomeric pad bearings without RC shear keys, the sliding effect of the elastomeric pad bearings plays an important role in isolation of ground motions and, however, lead to lager bearing displacement that consequently increases the seismic risk of fall of span, especially under earthquakes that contain significant mid-period contents or velocity pulse components. It is suggested from the test results that RC shear keys should be elaborately designed in order to achieve a balance between isolation efficiency and bearing displacement. Good correlation between the analytical and the experimental data indicates that the analytical models for the bearing and RC shear key as well as other modeling assumptions were appropriate. 相似文献

Drawing on theories of space, gender, and participatory learning, central concepts in feminist pedagogy, the author designed a university-level general-education course that took the Twenty-Five Ladies Tomb in southern Taiwan as the focus of a field study and class discussion. This local gendered site, which commemorates a 1973 ferry accident that killed 25 unmarried young women working in Kaohsiung, raises issues about patriarchy in Taiwan, gender inequities in traditional Han customs, and women's labor. The course relied on guided class discussions and focus-group discussions, culminating in a visit to the site. Face to face with the researched, the author not only built an inclusive and supportive relationship with students in the classroom, but also put her researcher's reflexivity into teaching practice. Research results indicate that the freedom of the class discussion format succeeded in breaking down the logic of binary opposition that accompanies the traditional gender duality of male/female. Avoiding a top-down teaching style also minimized students' resistance to perspectives emphasizing gender equality. 相似文献

The article reviews three major controversies in the microfinance field: vehicles, technologies, and performance assessments for financial service delivery. Then it proposes that these controversies be resolved by a perspective emphasizing institutional plurality and external and internal efficiencies for individual programs. Questions for further research are discussed in the conclusion. 相似文献

知青运动已成为历史。知青上山下乡,是新中国农业改革过程中非常独特而重要的内容。在此过程中,知青经受了严峻考验,付出了青春代价。知青所形成的人生感悟和人生经验,具有独特的内涵及意义,必须如实记载,存史资治。当前应大力倡导知青通过回忆,将当年的生产和生活片段记录下来,为以后的修志奠定基础。知青回忆,要充分利用集体的动力及智慧,正确选择有关对象与方法,确保真实与表达的科学,让社会能够接受,这样其价值才能体现出来。 相似文献
