Emergency centers, communication systems, and hospitals are essential infrastructures for emergency rescue and subsequent reconstruction activities. An investigation into the Nepal 2015 earthquake sequences found that the visited government offices were functioning normally 40 days after the main shock; that the local media failed to coordinate with the entire society at the beginning, but mobile phone-based communication recovered quickly; and that the hospitals in high-intensity areas were badly damaged as a result of improper design and adverse site configuration. Recommendations are proposed to enhance the aseismic capacity of structural and non-structural components using earthquake early warning and base isolation. 相似文献

This study examines the settlement intentions of migrants based on original survey data collected from four large Chinese cities. Despite the long-lasting institutional effects of the hukou (household registration) system, market mechanisms are becoming increasingly important in affecting migrant settlement intentions. Although rural hukou holders are more likely to return to their places of origin, migrants who have received higher education, who are self-employed or who own homes are more willing to permanently settle in cities. The influences of market mechanisms are also reflected in recent policy reforms related to education, housing and the hukou system. 相似文献

Lead isotope ratios of 15 Chinese bronze artifacts from the Yejiashan site (Suizhou City, Hubei Province) were analyzed and compared with copper ores across China. This study attempts to provide a new perspective to discuss the role that Zeng State played among all the vassal states in the early Zhou dynasty (ca. 1046–977 BC). The political presence of the Zhou dynasty in the middle Yangtze Plain is another main content of this paper. The lead isotopic characteristics of Chinese bronze artifacts between different historical periods are also in the scope of the study. By comparison, the lead isotopic ratios of the tested bronzes and copper deposits in the north Jiangxi Province show numerous overlaps. It indicates that the tested bronzes might have a single ore source, and this source was in the south of the Zhou dynasty. Combined with history and archaeological records, it is highly likely that the middle Yangtze Plain might be a part of the Zhou dynasty since the very beginning. Moreover, Zeng State might have a great influence in the ancient middle Yangtze Plain, and the nobles of Zeng State might even have authority to supervise certain area extending to Jiujiang. As lead isotopes of the bronzes appear to show a clear relation to chronology, the change of lead isotope patterns across times may further serve to distinguish the bronzes of the Western Zhou dynasty from the late Shang ones. 相似文献

至正十一年铭青花云龙瓶考 总被引:1,自引:0,他引:1
至正十一年铭青花云龙瓶是一对专门订制的庙宇供器,它的产生与宋元时期南方的五显神信仰有关。其最初供奉地是距景德镇约68公里的婺源县灵顺庙,供奉对象是五显神的从神"胡靖一"。供奉者张文进是距离景德镇约110公里的信奉五显神的商人。承造这套青花瓷瓶的是生产元青花瓷器的中心窑场,其地点可能在今景德镇市区内。 相似文献

中国战区接受投降的日本陆海军单位与人数考订 总被引:2,自引:0,他引:2
向中国战区投降的5支日军部队是:陆军中国派遣军、第10方面军、第38军,海军中国方面舰队、高雄警备府。包括陆军的1个总军、3个方面军、10个军与作战部队36个师团、41个独立旅团、13个独立警备队、1个支队;海军的1个方面舰队、2个警备府与6个根据地队、4个陆战队、1个航空战队、2个警备队。投降日军官兵陆军120.47万,海军近11万,合计131.4万余人,而不是通常资料的128.324万人。一些资料关于投降日军单位与人数的不准确记述多缘于对日本海军的误解,尤以遗漏高雄警备府为甚。 相似文献
