《汉郊祀歌十九章》是汉武帝时祀五郊的乐歌。它虽然歌辞古奥艰深但在艺术上取得了相当的成就。它以简练传神的语言营造出杞神迎仙的神秘氛围:发挥神奇的想象,运用大胆的夸张,塑造出生动的神的形象来表达人的理想,并且用虚实相生的艺术手法描写祥瑞符应;艺术形式和风格上表现出自由灵活,挥洒自如的创造特色。 相似文献

Hydrothermal fluid is essential for transporting metals in the crust and mantle. To explore the potential of Cu isotopes as a tracer of hydrothermal-fluid activity, Cu-isotope fractionation factors between Cl-bearing aqueous fluids and silicate magmas (andesite, dacite, rhyolite dacite, rhyolite and haplogranite) were experimentally calibrated. Fluids containing 1.75–14 wt.% Cl were mixed together with rock powders in Au95Cu5 alloy capsules, which were equilibrated in cold-seal pressure vessels for 5–13 days at 800–850°C and 2 kbar. The elemental and Cu-isotopic compositions of the recovered aqueous fluid and solid phases were analyzed by (LA-) ICP–MS and multi-collector inductively coupled plasma mass spectrometry, respectively. Our experimental results show that the fluid phases are consistently enriched in heavy Cu isotope (65Cu) relative to the coexisting silicates. The Cu-isotope fractionation factor (Δ65CuFLUID-MELT) ranges from 0.08 ± 0.01‰ to 0.69 ± 0.02‰. The experimental results show that the Cu-isotopic fractionation factors between aqueous fluids and silicates strongly depend on the Cu speciation in the fluids (e.g. CuCl(H2O), CuCl2– and CuCl32−) and silicate melts (CuO1/2), suggesting that the exsolved fluids may have higher δ65Cu than the residual magmas. Our results suggest the elevated δ65Cu values in Cu-enriched rocks could be produced by addition of aqueous fluids exsolved from magmas. Together with previous studies on Cu isotopes in the brine and vapor phases of porphyry deposits, our results are helpful for better understanding Cu-mineralization processes. 相似文献

《封禅方说》原书已佚,无法详考该书与汉武帝的关系.现存《史记·孝武本纪》几乎与《史记·封禅书》完全相同.根据《史记·封禅书》、《汉书》、《风俗通义》等相关记载,可大略推测汉武帝不得不封禅是《封禅方说》的成书背景,汉武帝时期的方士之风加速了《封禅方说》的形成,以公孙卿为代表的方士群体创作了《封禅方说》.汉武帝晚年对求仙态度的转变是《封禅方说》一书散佚的重要原因. 相似文献

《五臧山经》是古代巫师祭祀山神的祀典记录,从中可以看出：当时祭山祀礼没有特定的时间,祭品简单且大体相同,祭祀仪式与程序简省,祀礼亦无明显的等级差别,它反映出了古时祭山祀礼的古朴特征。至今一些偏远地区仍然保留着这一风俗,这是远古民间祭祀的现代遗存。 相似文献

《安世房中歌》与《郊祀歌》由于产生时代和祭歌性质的不同,在主旨、祀神态度、歌诗源流及其音乐特征呈现出较大差异的个性特征,由此可以窥见西汉祭祀诗歌的不同面貌。 相似文献

"大传统"与"小传统"理论对中国当下的学术产生了影响,这种理念被广泛地运用于学术研究的诸多领域.本文以西晋郊祀制度为例,揭示儒学作为大传统如何规范皇帝亲祠、规范郊祀制度,从而使秦汉以来神仙方术与民间淫祠杂祀等小传统淡出郊坛. 相似文献

“杠天神戏”是流传在洪河、汝河、史灌河入淮（河）口一带的以娱神为主要目的的民间祭祀戏曲。它是伴随着这一地区人们的信仰归属而产生,充分体现了“杠天神戏”在豫南皖西民间信仰中所发挥的祭祀功能、仪式功能和表演功能,同时也反映出豫南皖西民间独特的信仰表达方法。 相似文献

In the present study, in the first part for a spherical vessel with known dimensions and working pressure, two methods of hoop and equivalent stress optimization across the wall thickness are employed to determine the best autofrettage pressure. In the next part for a predefined working pressure the minimum wall thickness of the vessel is calculated using two other design criteria i.e. (A) optimizing the hoop stress, and (B) assuming a suitable percent for the penetration of yielding within the wall thickness. Finally, the optimum thickness and the necessary strengthening pressure are extracted and different plots are introduced for different types of structural materials under different internal pressures. 相似文献

据苗族史诗记载，苗族先民最初在长江中下游完成了从旱作到稻作的转换。由于战争及迁徙，打乱了苗族稻作文化发展的正常进程，继而在西南山区创造、再生出了适应地理环境的农耕梯田文化。苗族鼓社及原始祭祀，紧扣节日和农时节令，围绕稻作生产的各个环节，与稻作农耕活动融为一体，并整合、传承了鬼神崇拜、祖先崇拜及生殖崇拜等文化因子，使稻作文化与祭仪构成了一种互动共生的紧密关系。 相似文献
