龙游石窟砂岩的水稳定性研究   总被引:1,自引:0,他引:1  
通过对龙游石窟砂岩胶结泥质中粘土矿物—蒙脱石的性质和结构特征;岩石中各类矿物在水中溶解度的变化;岩体与水反应的表面积,即岩石的孔隙率;与其相作用的水的化学性质,特别是水的pH值变化等方面的测试研究,证明被淹没在水下的石窟砂岩洞室相对较稳定。但洞室的水被抽干后,由于水环境的突变以及随后环境湿度的频繁变化,大大加速了洞室的风化。  相似文献

自古埃及以降的闪米特文明都有神奇蛇的信仰,但这些蛇都是克托尼俄斯的神物,代表地下界,从不升天也不飞翔,这种信仰符合蛇的自然本质。中国的龙为天神,既不符合蛇的本质,又和其他古文明崇拜的蛇神形象大异其趣。中国龙的形象来自昆虫。在大自然中,只有昆虫能由蛇体化为鸟形,也只有昆虫能暂死后再生、升天。古人神化昆虫,这实为龙的形象与崇拜来源。不同地区的萨满教,都有崇拜昆虫变形、羽化神能的痕迹。中国先民确有尚虫信仰。中国龙可能更近似于古埃及的金龟蜣螂甲虫崇拜。尽管埃及的金龟和中国的龙崇拜在起源、发展上关联性不大,但两者的信仰观念与象征意义却相当接近。夏禹形貌为虬龙,其名"禹",恰和"虫"同字,故龙、虫义同。  相似文献

清末民初北京地区的社会变迁与慈善组织的转型   总被引:5,自引:0,他引:5  
王娟 《史学月刊》2006,280(2):96-104
北京地区的传统慈善组织在清末民初发生重大变化:数量上呈现较大幅度的增长趋势;救助功能方面普遍地由施养向教养转化;操作管理方式逐渐走上联合统一的道路。这些变化与北京地区在近代所具有的典型社会特征有着密切联系,因此一定程度上本文是对慈善事业研究的一种区域性探索。  相似文献

建国前夕和建国初期,中财委在领导全国稳定物价和统一财经的工作中,通过贸易系统的恢复和商业资本的注入,复苏了被国民党政府及长年战争中断的城乡交流。随后,中财委在工商业调整中拟订了收购土产等政策并转交了城市经营方针,进一步推动了城乡交流的发展,使国内经济得以恢复,并为中国工业的发展提供了正确的发展方向和路径。回顾这段历史,对于我们统筹好当今的城乡关系具有重要的启示和借鉴意义。  相似文献

清末财政困窘,支出浩繁,政府在维持旧有税收的同时,力图开辟新的税源,并因应时势而不断变化,酒税从厘捐到烟酒税这样的变化就体现了这一发展历程。民国初创,面临的财政危机依然如故,酒税征收仍然沿习清末旧制,弊病百出。当政者对酒税制度重新设计,意欲将其纳入国家财政收支系统的正轨。对原有酒税加以改革,举办公卖制度开征公卖费,新征烟酒牌照税,构成了民国初年酒税制度的主要内容。然而由于各种各样的原因,这一努力并没有达到制度设计者的初衷。  相似文献

Abstract

The article aims to highlight the features of socialist anticommunism in Italy from 1945 to 1991, with particular reference to Giuseppe Saragat and Bettino Craxi, and with regard to the intellectual activity of Ignazio Silone. Anticommunist socialists aimed at delegitimizing the communists, but they themselves were also delegitimized by the communist party of Palmiro Togliatti and Enrico Berlinguer. Naturally, the form of delegitimation changed over the years, from Saragat’s stance in the 1940s and early 1950s to his position later on. The kind of delegitimation carried on by Bettino Craxi’s socialist party was more successful, however, compared to the one implemented by Saragat’s small party. For this reason, it was fiercely opposed by Berlinguer and the communist party.  相似文献

A mathematical theory is developed to demonstrate the disputed hypothesis that hunting tribes of the Upper Paleolithic in Europe did play a decisive role in bringing about the extinction of the mammoth and other large herbivorous animals at the end of the Pleistocene. Formulas for the periods of time during which hunting did not greatly affect animal numbers and during which the numbers declined to zero are used to show that mammoth numbers remained relatively stable during most of the Upper Paleolithic (a period of 10,000 to 25,000 years) and then dropped rapidly within a few centuries to complete extinction. The theory is used to explain why only the largest animals became extinct and why elephants continued to survive in tropical areas while the mammoth vanished in the north.  相似文献

殖民地印度时期,在南亚次大陆上分布着560多个土邦。二战后英国工党政府背弃了以往保守党的土邦政策,采取了理论上继续支持王公、现实中则背弃王公的两面性政策。代表英王的副王和政治部支持王公拥有成立自治领的权力,试图以此为筹码为王公的未来争取更多的利益,而其真实态度则是鼓励宗主国从土邦撤离,要求王公加入未来的新政府。在印巴分治的前夜,英属印度政府成立土邦部,出台《加入协定》,采取了威逼利诱的两手策略。宗主国的政策转变、政策的两面性、对土邦态度的暖昧性和土邦策略的两手性使王公被迫加入了新成立的自治领,致使印度王公消失。  相似文献

文章对明清时期东北边疆城镇兴衰过程进行了探讨。认为由于战略地位的重要和军事斗争的需要 ,明在辽东兴建了大批城镇 ,但至明清之际 ,因后金 (清 )采取了“毁城迁民”的政策 ,明代以来在辽东地区兴起的城镇遭到了毁灭性打击。至康熙中期 ,辽东城镇仍未恢复元气 ,其原因主要在于大量人口的外迁和清在东北实行封禁政策。  相似文献

实现中华民族的伟大复兴,是每一个炎黄子孙的夙愿,也是中华人民共和国的发展目标。历史来看,实现中华民族伟大复兴的根本在于有一个能承担历史使命的政党,关键在于创新,途径在于走中国特色社会主义道路,基础在于最广泛最充分地调动一切积极因素。中华民族的复兴,决不是提倡狭隘的民族主义,而是从中华民族的历史实际出发,从我们现在处于发展中国家、落后于世界先进发达国家的现状出发,追求自身的经济发展和社会进步。  相似文献

东汉末年的党锢之祸是中国历史上第一次大规模的党争,历来受到研究者的关注,然题中仍不乏剩义。本文主要考察党锢的缘起及党人集团失败的原因。笔者认为党人集团的失败绝非偶然,至少有三方面的原因值得总结。其一,把宦官作为败坏东汉政权唯一的罪魁祸首有失公允;其二,清流官员欲尽除宦官的计划得不到最高统治者的支持,且他们的过激言论招致皇帝的震怒;其三,党人集团中缺少雄才大略的领袖,在关键时刻优柔寡断,致使功败垂成。  相似文献

The author views British Columbia as a typical newly developed industrial region of the advanced capitalist countries, in which stress is placed on the development of raw materials and semi-finished goods for the export market. The region's transportation, electric power, metallurgical and forest industries are reviewed in detail. High labor productivity and advanced technology are found to be typical of the development of British Columbia, whose experience is found applicable to parts of Siberia.  相似文献

Abstract

The techniques of spatial analysis are deployed to gain insights into the ways in which smaller churches of the 11th and 12th centuries were designed to be used. A range of plan types is discussed, including churches with one, two and three cells, linear and cross-shaped plans, and ‘round’ churches. The resulting analysis of the forms of buildings is then placed in the historical context of ecclesiastical reform, and it is argued that some of the changes in church layout were designed to separate the clergy from the laity, mirroring their increasing legal and social differentiation. It is also argued that the ways in which clergy used space were similar in all types of church examined, and that they show continuity from early Christian buildings to the late 12th and 13th centuries, when rising belief in the transubstantiation of the Host led to the evolution of new forms of clergy space  相似文献

In the nineteenth century, after the separation from the Spanish Crown, the invention of the Andean nations required an autochthonous group, the independence of which could be celebrated. At first sight, it might seem that only the American Indians could play this role, but this idea rapidly ran into a fatal contradiction with the contempt for the Indians of the promoters of the new republics. In addition, it was necessary to build a new identity on many disparate elements to set oneself apart from European origins. In this manner, a suitable mythical autochthony has been invented, built on the image of the Imperial Indian, the descendant of the Incas. The indigenista movement of the 1920s has greatly contributed to the making of this national representation of Peru. This article traces the evolution of this tradition and its principal actors, and describes its underlying tenets. It attempts to picture recent neo‐Inca re‐inventions, especially the emergence of a ritual Inca king in the neo‐cult of the Sun, and the enthronement of the President of the Republic by shamans at the sacred site of Machu Picchu. Finally, it points at recent New Age extensions of this tradition. The article tries to show how mythological constructions of the past are instrumentalized to build the historical foundations of a present‐day nation, and how at the same time they are being taken over by a worldwide ideology.  相似文献

1949年1~2月间,在中国革命即将取得全面胜利之际,苏联驻华使馆却令人吃惊地追随正在逃亡的国民党政府由南京迁至广州.有关苏联驻华使馆撤离南京的真正用意,是史学界长期以来关注的焦点,同时也是部分研究成果论证苏联、斯大林本人怀疑中国革命说法的基础.实际上,苏联驻华使馆撤离事件是苏联方面采取历史上惯用的双重对华政策的必然结果,既不是苏联方面对中国革命的进程判断失误,也不是苏联方面坚持了不干涉中国内政的原则.相反,在意识形态(革命利益)和国家利益之间发生冲突的时候,苏联方面首先选择的是自身国家利益.苏联驻华使馆在新中国成立前的撤退,符合苏联的国家利益,最大限度地保护了苏联在华的政治和经济利益.客观地看,苏联驻华使馆由南京撤至广州作为外交手段捍卫国家利益本无可厚非,但从联共(布)和中共共同的革命利益出发,上述做法显然欠妥.  相似文献
