此次有机会到甘肃省的临夏去考察了解该地区的土族,感触极深,获益也极大。实地考察的结果证实了临夏地区不仅是土族先民在西北地区最先开拓的疆土之一,也是其后裔繁衍生息的主要地区之一。土族先民们在那里开拓奋斗了很长时期,并以此为根据地,再向南、向西、向北开拓发展,曾成为我国历史上西部开发者中具有极大影响的古代少数民族之一。 相似文献

Trepanation skulls have been found clustered in the Gan-Qing region of northwestern China, where the trepanation also demonstrated more signs of healing than those from other areas. In this study, two skulls belonging to the pre-Qiang people from the Mapai cemetery in the late Neolithic period in the Gan-Qing region with trepanation were observed using ultra-depth electron microscopy and CT imaging. Moreover, trepanation experiments were conducted to test different tools and tool combinations to investigate the trepanation technique used by the pre-Qiang people. Results demonstrated that the trepanation openings with signs of healing were the work of experienced trepanation practitioners, most likely for therapeutic purposes. Our experiments also demonstrated that different tools need to be used to generate similar perforations, suggesting a mature trepanation procedure by the pre-Qiang people. Although it seems clear that the two individuals in this study underwent neurosurgical operations, it is impossible to determine why that surgery was performed. The trepanation phenomenon of the Gan-Qing region enriches our knowledge of lifestyles, health status, and primitive yet then advanced medical techniques and healthcare. 相似文献

清朝初期,围绕着收复台湾的问题,郑成功和施琅展开了针锋相对、你死我活的斗争。而强烈的个性冲突以及彼此之间利益的对立,是导致他俩人从朋友到敌人、从合作到对抗变化的主要原因。 相似文献

历史时期南方山区经济开发的进程,可区分为三个阶段:(1)自原始稻作农业起源,至2世纪末,南方山区的经济形态以采集渔猎为主、原始种植农业为辅;(2)自六朝至北宋末,低山丘陵地区的河谷、山间盆地逐步被开垦成农田,局部地方形成了梯田,建设了中小型农田水利,但刀耕火种性质的烧?仍是南方山区主导性的垦耕方式;(3)自南宋以迄于明清时期,浙闽山地、南岭山地、川东丘陵山地、粤桂山地、秦巴山地渐次得到全面开发,特别是明清时期,各省际交边山区成为主要开发对象,山地利用达到了新的高度。 相似文献

浅淡中国古代金属货币的制造加工技术 总被引:1,自引:0,他引:1
本文通过对古代范铸技术铸钱的研究,提出了古代铸钱工艺是采取了多种铸造技术。通过采用砂型工艺铸钱的实践,提出了秦代也可能采用过砂型铸钱工艺。通过对出土文物的研究,证明圆形方孔钱的铸后加工技术,早在汉代就已经形成了规范的加工方法。 相似文献

This research is based on the understanding that the house form shapes and is shaped by predominant socio-cultural values and norms. The study outlines how the physical evolution of the Korean house form, specifically its heating system called the ondol, has been part of Korean women's lives since the fourteenth century. In particular, however, I focus on the twentieth century. I first describe how the physical structure of the Korean house and the ondol evolved in conjunction with larger societal changes during this period, arguing that these technological changes have substantially influenced the everyday practices of women, the social interactions among family members at home, and women's experiences of being at home. Second, and in order to provide more in-depth analysis of these interactions, I look to the results of 30 interviews with Korean American seniors. This study suggests that the living experiences of the residents were variously affected by their gender and generational relationships within the family. 相似文献
