秦、西汉时期关中农业发展的地域差异 总被引:2,自引:0,他引:2
在秦汉定都关中期间,围绕都城的建设与发展,关中内部的农业生产格局发生了较大变化,生产重心日益向东北方向倾斜。西汉后期关中东部渭北地区是关中农业生产的重心;西南部的农耕经济则几乎完全遭到毁灭;西北、东南部的农业生产虽有较大发展,其速度较东北部而言,却相对缓慢。 相似文献

The Russian mathematician and physicist Friedmann and the Belgian priest and physicist Lemaître were the first to consider non‐static world models in the framework of Einstein's general theory of relativity. Friedmann seemed to favour a periodic, oscillating cosmological model. His investigations were taken up by Russian cosmologists in the 1960s. They stated that the singularities present in many of the Friedmann‐Lemaître cosmological models seemed to be artificial and were ascribed to the assumption of a highly symmetric distribution of cosmic matter. Their disapproval of singularities seems to be in accord with Soviet ideological requirements during that time like atheism and dialectic materialism. They had to retract their statements after Hawking had proved his singularity theorems and after the microwave background had been discovered. Hawking followed the line of thought which was initiated by Lemaître in the early 1930s. Lemaître had combined for the first time quantum physics and relativistic cosmology and had developed his idea of the primeval atom, a beginning of the universe in a dense state with just one quantum containing the whole mass of the universe. Pope Pius XII brought together this primeval atom and God as the Creator of the universe and declared in 1951 that big bang cosmology is compatible with the Bible. Not surprisingly Hawking was awarded the Pius XI medal by the Vatican in 1975 for his contributions to big bang cosmology. 相似文献

This article takes the case of “rouge pot” fragments found in an archaeological context in New Orleans’ French Quarter associated
with the circa 1822 Rising Sun Hotel and investigates the discourses and desires that shape our interpretations of artifacts.
We argue that archaeological, historiographic, and public desires overlap and inform one another in a complex web of relations.
In New Orleans, the particular web into which the archaeology of cosmetic jars and hotel sites can fall is spun by the ways
in which the former French colonial capital is sexualized in both textbooks and folk songs. 相似文献

京军本为守御京师(畿)而设,但随着政局的稳定和社会经济的发展,皇亲贵戚的生活越来越奢华,京城内的工程修建越来越多,大批京军被抽调借拨到建筑工地,一部分京军竟然演变成职业建筑工人。京军参与修筑的建筑物主要是宫殿庙宇。京军修筑虽然组织方便、节省费用,却严重影响到军队的战斗力,加速了军队的衰败,这也是明朝灭亡的一个重要因素。 相似文献

历史时期的"黄河清"现象初探 总被引:2,自引:0,他引:2
古人对黄河清有“祥瑞之兆”和“不祥之征”两种观点。黄河澄清是一种自然现象,却又不可能出现在正常条件下,它有其内在的规律。只有当流域内大范围出现异常情况,如持续干旱少雨、冬季过于寒冷、地震等时,才会导致黄河河水变异,出现黄河澄清的现象。黄河清是干旱和黄河断流的前兆。同时,黄河清还与社会政治、化和生活交织在一起,成为奇异的化与社会现象。 相似文献

秦汉政治史观的演变历程 总被引:1,自引:0,他引:1
秦汉时期共有三种主要的政治史观:以五行相胜原则运转的五德终始说、以五行相生原则运转的汉为尧后说,以及董仲舒所创三统说。秦到汉武帝时,五行相胜的五德终始说占政治史观的主流,汉昭帝以后则被五行相生的政治史观代替,董仲舒创立的三统说在汉武帝时形成,此后便和五行相生政治史观平行发展。这三种政治史观都与阴阳五行有密切关联,并对秦汉乃至以后两千余年封建社会产生深远影响。 相似文献

Much of the debate surrounding the inclusion of women in the study of international politics, particularly in reflections of war, promotes passive representation. State-sanctioned images of non-combatant women in supportive wartime roles reflect, rather than confront, traditional conceptualisations of 'legitimate knowledge' and ways of knowing. Therefore, estimates that 30,000 women were raped during the war in Bosnia shocked the international community. Yet it shouldn't. War rape is as old as war itself. This article looks at why, and how, traditional forms of theorising about international politics fails to identify or vocalise the violent insecurities of women in domestic and international space, thus ensuring women's silence. It also draws on alternative ways of knowing to confront the tradition and to un/recover the experiences of women. 相似文献

During the Neolithic period, the Chengdu Plain was a key region where two important crops, rice and millet, were cultivated together. Millet was probably introduced from north-western China c.3500–3300 cal. bce , and rice came from the Middle Yangtze River c.2600 cal. bce . In this study, human and faunal remains, as well as charred crop grains, were collected from the Yingpanshan (3300–2600 cal. bce ) and Gaoshan (2500–2000 cal. bce ) sites where the dominant crop was millet and rice, respectively. Carbon and nitrogen isotope analyses were conducted on human bones and the ecofact samples in order to reconstruct the subsistence at the sites. The results indicate that the diets of two individuals recovered from the Yingpanshan site consisted of both C3- and C4-based foods, predominantly the former. By contrast, Yingpanshan pigs consumed a large quantity of C4 fodder. This result, combined with the ecofact evidence, suggests that millet was the main crop at the Yingpanshan site. It also highlights the fact that the two Yingpanshan individuals might be non-locals and/or belonged to later periods. On the other hand, the diet of the Gaoshan community was dominated by C3-based foods. When considering the archaeobotanical evidence at Baodun, a site contemporaneous with and near to the Gaoshan site, it can be stated that rice was an important food resource for the Gaoshan community. This study also suggests how crops were managed at the two sites. The Yingpanshan people might have used manure for growing millet. Both manuring and irrigation might have also been practised by Gaoshan's rice farmers. However, more studies are required to understand the extent of manuring and irrigation in their agricultural economies. 相似文献
