随着康熙、乾隆的北巡,避暑山庄及周围寺庙相继诞生,承德成为清代第二个政治中心和外交的舞台。承德地区历经三百多年的发展,逐形成颇具特色的地方文化,其成分有满、汉、蒙,甚至包含西方文化艺术等。在京津冀协同发展的大战略下,如何把承德打造成国际旅游城市、京津冀生态文明示范区已成为当务之急。保护和利用承德传统地方文化资源,整合承德历史人文景观,引导承德旅游市场走向成熟,成为国际高端旅游产品,从而带动承德经济快速稳定发展。 相似文献

孝既是人性自然也是文化情结。孝歌分为“阴”“阳”两大类。商南阳类孝歌的主题是传达父母的养育之恩,教导子女如何在日常生活中行孝。阴类孝歌有着俗成仪式套路,贯穿阴阳理论和善恶报应思想。商南孝歌是原生态的地域文化,有独特的文化审美意蕴。 相似文献

景颇族“目瑙纵歌”盛会以董萨带领其神职人员为群众祭献以“木代”为首的诸鬼为序幕,以祭祀“木代”为开场,以献歌舞祭祀送鬼为收尾。以巫师作法杀牲祭祀为基本形式,祈福镶灾为根本的宗旨,表现了景颇族具有原始宗教信仰的祭祀性质。 相似文献

在中国古代传统文化中,国家祭祀一直是国家政治权力的象征,而礼官作为司礼的专职官员,担任国家祭祀典礼的策划与主持。在唐代重文的风气下,文人是组成唐代礼官的主力。礼官文人的命运常常同政治气氛紧密联系在一起。随着有唐一代的政治社会变迁,国家举行祭礼的目的和能力有很大差异,这种差别直接影响到礼官文人的人生轨迹,决定了他们的政治命运。 相似文献

基诺族在以"刀耕火种"为主,采集、狩猎为辅的传统农业体系中,发展出了一套完整的农业祭祀礼仪,其涉及了从备耕到收获的各个阶段。农业祭祀礼仪除表达了人们祈求丰收的愿望之外,还调整和重新安排了人们的生活节奏,促进了社会的整合;同时在仪式举行的过程中也完成了社会成员的社会化。从传统来看,基诺族在这些生产活动的仪式性表达中,呈现出自己的宇宙观和价值观,明确了自己在生态系统中的位置,也通过这些仪式传承了农业生产知识,加强了群体认同,维系了社会的存在与发展。然而,随着社会大环境的改变,基诺族的农业及其祭祀礼仪也发生了巨大变迁。 相似文献

Cold-stretched pressure vessels from austenitic stainless steels(ASS) are widely used for storage and transportation of liquefied gases,and have such advantages as thin wall and light weight.Fatigue is an important concern in these pressure vessels,which are subjected to alternative loads.Even though several codes and standards have guidelines on these pressure vessels,there are no relevant design methods on fatigue failure.To understand the fatigue properties of ASS 1.4301(equivalents include UNS S30400 and AISI 304) in solution-annealed(SA) and cold-stretched conditions(9% strain level) and the response of fatigue properties to cold stretching(CS),low-cycle fatigue(LCF) tests were performed at room temperature,with total strain amplitudes ranging from -.4% to -.8%.Martensite transformations were measured during the tests.Comparisons on cyclic stress response,cyclic stress-strain behavior,and fatigue life were carried out between SA and CS materials.Results show that CS reduces the initial hardening stage,but prolongs the softening period in the cyclic stress response.Martensite transformation helps form a stable regime and subsequent secondary hardening.The stresses of monotonic and cyclic stress-strain curves are improved by CS,which leads to a lower plastic strain and a much higher elastic strain.The fatigue resistance of the CS material is better than that of the SA material,which is approximately 1?03 to 2?04 cycles.The S-N curve of the ASME standard for ASS is compared with the fatigue data and is justified to be suitable for the fatigue design of cold-stretched pressure vessels.However,considering the CS material has a better fatigue resistance,the S-N curve will be more conservative.The present study would be helpful in making full use of the advantages of CS to develop a new S-N curve for fatigue design of cold-stretched pressure vessels. 相似文献
