甘肃是中国石窟艺术最为集中的地区之一,地处甘肃东南部的陇南地区由于地理位置偏僻,社会经济发展水平相对落后,石窟的开凿较省内其他地区偏晚,始于北魏末年,发展于隋唐阶段,兴盛于明清时期。其窟龛形制、造像题材受到了天水麦积山石窟等毗邻地区佛教艺术的影响,且区域内呈现出不平衡的地区分布特征,明清时期这种局面得以改变,并最终形成以儒、释、道三教为核心的多神信仰体系。 相似文献

沈阳故宫藏有明代犀角雕玉兰花杯、犀角镂雕梅花杯、清代染角透雕人物船、兽骨镂空花翎折扇、牙雕巧工葫芦、牙雕草蝶形盘、贝浮雕鱼等精美的雕刻艺术品。当这些雕刻艺术与清官的陈设品相结合之后,它的辉煌又在木质光华中闪耀。 相似文献

养生汉画像石是汉文化的重要组成部分,体达着“下根”之人对于道教义理的认识和选择。以往相关研究多流于图像内容的阐释,着力点在于将该类画像还原成文献,缺乏对图像形式背后所隐藏观念意味的关注,未曾从道教房中养生思想对汉画观念浸润的层面作深入考察。房中养生画像石刻是对特定历史时期道教养生观念的诠释和图解,它的出现,与汉代特殊的人文环境有着密切的联系。 相似文献

日本的建筑,包括城池、庙宇和民居,都深受中国的影响,京都、奈良就是按古长安的模式建造的,连平城京宫的12道门,均取长安城门之名命之;特别是建筑风俗的理念,基本上是中国风水理论的演绎,五行四象布局被普遍认同。日本明治维新以后,由于工业社会的影响和西方文化的冲击,人们在接受中国传统思想的同时,又企图以现代科学的方法加以实证,使这些传统变得更加理性和严谨。而中国的建筑民俗,一方面由于统治思想的打压,被视为“封建迷信”,潜流于乡间和底层社会;另一方面主流社会为适应政治经济和观光旅游的需要,变换形式加以炒作,使其功利目的更为彰显,双方都在按各自的套路发展。 相似文献

Basic climatic elements and factors of climate formation in the Central Economic Region are assessed with a view toward improving methods of short-term forecasting. More specifically, analysis of the spatial variation of radiation, evaporation, and turbulent heat transfer, patterns of the most economically significant climatic elements; and trends in temperature and precipitation relative to long-term means sets the stage for a discussion of problems in forecasting the length of the heating season and in predicting precipitation anomalies one year into the future (translated by Andrew R. Bond). 相似文献

In this paper, the Member Discrete Element Method (MDEM) is modified and perfected for three aspects: the algorithm itself, loading and computational efficiency, and to accurately and quantitatively simulate the progressive collapse for large-span spatial steel structures. In addition, the corresponding computational programs are compiled. First, from the perspective of the method, a meshing principle for discrete element models is determined, a treatment for material nonlinearity and strain rate effect is proposed, and a damping model is established. Next, the Displacement Method is introduced to determine the multi-support excitation for the MDEM, and then motion equations of particles under multi-support excitation are derived. On this basis, the specific process of gravitational field loading is presented. Furthermore, parallel implementation strategies for the MDEM based on OpenMP are constructed. Finally, the collapse simulation of a 1/3.5-scaled single-layer reticulated dome shaking table test model under multi-support excitation is carried out. The comparison demonstrates that the ultimate load and failure mode as well as the complete collapse time of the numerical results are consistent with the experimentally measured responses, and the configuration variations from member buckling and local depression until collapse failure are fully captured. Moreover, the displacement time-history curves obtained using MDEM are almost identical to the experimental measurements, and there is a nuance only in the amplitude. It is verified that MDEM is capable of precisely addressing the collapse failure for large-span spatial steel structures. Additionally, the failure mechanism for structures of this type is naturally revealed. 相似文献

ABSTRACTThe emerging problem of left-behind children has attracted mounting academic and policy attention. Prior studies primarily cast light on left-behind children’s education, health, and behavior, while their subjective well-being is much less understood yet. Based on a nationally representative sample of rural children aged 10–15 in 2014, we examine the impacts of different types of parental migration on children’s subjective well-being and how these affects vary between boys and girls. The results show that parental migration is a double-edged sword: children from both-parent migrant families report compromised life satisfaction and relationship quality compared with those in integral families, and mother-only migration significantly lowers children’s subjective health. On the flip side, father-only migration enhances children’s aspiration for attaining college, an encouraging effect that is even stronger than that of parental education and family income. These effects are heterogeneous by children’s gender: boys seem to be more susceptible to the disruptive effects of both-parent migration; mother-only migration effectively promotes girls’ educational aspiration while father-only migration promotes boys’. This study portrays a comprehensive image of left-behind children. Relaxation of hukou restriction, equal access to education, and revitalization of rural economies are imperative to improve the well-being of left-behind children.Abbreviations: LBC: Left-behing children; SWB: subjective well-being 相似文献
