唐太宗曾言:"以史为鉴,可以知兴替。"如果能将历代人对当时国家社会治理的满意度与现在作比较,就可以知道现在哪些地方做得好、哪些地方需要改进。本文以唐人诚信故事为例,论述了大唐精神中最有价值的自爱、自信、自尊和让天下人折服的诚信。  相似文献

Ginalski-type E5 button spurs made from a Cu alloy are a characteristic attribute of the Middle Roman period in barbarian Europe. The find of part of a mould made of non-ferrous metal at the Luleč site in the district of Vyškov, Czech Republic, provided key evidence for explaining the issue of their production. The discovery of this unique artefact showed that based on current knowledge, the spurs made from a Cu alloy were also produced in the Middle Danube region and not only in Northeast Europe as had previously been thought.  相似文献

长春地区城镇体系时空关联的异速生长分析:1949~1988   总被引:9,自引:0,他引:9  
运用分形思想和系统理论分析了长春地区各城镇40年间(1949~988)的异速生长关系及其分形演化过程,发现城镇体系时空关联的分维图式随着社会经济环境具有空间分异特征和时段阶变性质:只有具备健康的社会经济环境,城镇体系才能形成良好的分形性态。文章从时空关联的角度验证了城市系统的适应性假设和地理分形结构的优化猜想。  相似文献

公安部队是武警部队的前身,是中国人民解放军的一个组成部分。中华人民共和国成立后,为了在全国范围内迅速建立革命秩序,巩固新生政权,在中央军委和公安部的领导下,逐步把地域性的公安武装和中国人民解放军担负公安任务的部队正式改编成“中国人民公安部队”。在军委公安司令部成立后,公安部队又进行了整编,组建了“中国人民解放军公安部队”和地方公安部队,逐渐接替全国内卫任务。随着边防公安组织和边防武装的建立,全国公安部队初步形成了正规公安部队、地方公安部队和边防公安武装的体制。为统一对国家内卫、边防斗争的领导,加强公安部队的建设,1952年,中共中央、中央军委决定将内卫、边防和地方公安武装统一整编为“中国人民解放军公安部队”,全部纳入中国人民解放军的建制序列。内卫、边防工作和公安部队的建设进入了一个新的阶段。  相似文献

The discovery of a Neolithic Alpine jade axehead in Aroche, in the southwest of Spain, revives the question of long-distance exchange between the Iberian Peninsula and the rest of Europe. This polished blade belongs to a typological model quite characteristic of Alpine production during the second half of the 5th millennium B.C. Different mineralogical approaches (macroscopic features examination, specific gravity, direct XRD, non-destructive μXRF spectroscopy, optical stereomicroscopy, magnetic susceptibility determination and microprobe analysis) have identified the rock as an omphacitic jadeitite (mixed jade) with some tiny garnets and a weak retromorphosis. This analysis and the comparison of the rock structure with the referential JADE of Alpine natural jade samples, as well as the extraction modalities and shaping of the axe, provide strong arguments to assign the Aroche axe to a production of Mont Viso: the origin of thousands of axes that circulated in Europe between Ireland and Sicily. The Aroche axe, discovered not far from the variscite mines of Encinasola, could be considered as part of a possible exchange system between the Iberian Peninsula and the Gulf of Morbihan, in Brittany.  相似文献

There are several hundred recorded Early Upper Palaeolithic sites in Moravia, most of which are surface sites. The majority were exposed by agricultural plowing and subsequently discovered by pedestrian surveys whereas most of the stratified sites were found accidentally. Numerous unsystematic attempts in the past to find stratified remnants of sites disturbed by plowing have been unsuccessful. Here we present a methodology for locating stratified Early Upper Palaeolithic cultural contexts based on distribution of surface scatters. This involves pedestrian surveys guided by background research. All Palaeolithic artifacts were recorded using a handheld GPS with particular attention to calcium carbonate crust on artifact surfaces, which can be indicators of nearby stratified deposits. Exploratory test pits were then excavated followed by systematic excavations if the potential for stratified cultural deposits was deemed high.

Using this technique, we have discovered 11 new stratified Early Upper Palaeolithic sites.  相似文献

From the normative perspective of EU regional policy, polycentric spatial development has been seen as an effective tool to overcome regional disparities since the adoption of the European Spatial Development Perspective. However, the impact of a polycentric spatial structure on equal spatial development is ambiguous and still waits for its clarification. This paper examines the relationship by focusing on the local scale, where medium-sized towns play a crucial role as local centres in everyday human lives. Using functional regions of the Czech Republic, this paper defines polycentric urban systems at the micro-regional scale. Subsequently, the level of mono/polycentricity is compared with intra-regional disparities. Based on the results of the analysis, it can be argued that the connection of polycentricity with balanced spatial development is strongly determined by selected indicators. However, the findings do not provide evidence about the strictly positive impact of polycentricity on intra-regional disparities. In a light of these results, the conclusion is rather sceptical about the unique role of polycentricity in spatial development and due to the lack of similar studies, further research is recommended.  相似文献
