历史和基本国情决定了我国解决民族问题只能走民族区域自治的道路,这是解决民族问题的中国模式。民族自治与区域自治相结合的民族区域自治法律制度赋予少数民族地方“变通补充权”,体现了国家充分重视和保障少数民族管理本民族内部事务的权利。它与实行各民族平等、团结、共同繁荣的原则和国家法制统一原则是一致的。 相似文献

Zn0.99Cu0.01O films were studied experimentally and theoretically.The films were prepared by pulsed-laser deposi tion on Pt(111)/Ti/SiO2/Si substrates under various oxygen pressures to investigate the growth-dependence of the ferromag netic properties.The structural,magnetic,and optical properties were studied,and it was found that all the samples possess a typical wurtzite structure,and that the films exhibit room-temperature ferromagnetism.The sample deposited at 600℃and an oxygen pressure of 10 Pa showed a large saturation magnetization of 0.83μB/Cu.The enhanced ferromagnetism in the(Cu,Li)-codoped ZnO is attributable to the existence of Zn vacancies(VZn),as shown by first-principles calcu lations.The photoluminescence analysis demonstrated the existence of V Zn in both Zn0.99Cu0.01O and(Cu,Li)-codoped ZnO thin films,and this plays an important role in the increase of ferromagnetism,according to the results of first-principles calculations. 相似文献

黔东南侗族村寨法律“内化控制”的伦理基础——以南侗《劝世歌》和北侗《劝和歌》为切入点 总被引:1,自引:0,他引:1
徐晓光 《贵州师范大学学报(社会科学版)》2011,(2):66-74
南侗《劝世歌》和北侗《劝和歌》是侗族民歌中的特产,反映侗族人民的世界观、道德观、法律观、价值观和社会规范的要求。它的广泛传唱对侗族人民的道德内化和法律内化,促进侗族地区人与人、人与社会的和谐互动,增进侗族人平等互助、团结友爱,稳定社会秩序起到了重要作用,是侗族人民族道德法律"内化控制"民间口头文学文本。 相似文献

为了研究Mg ,Al掺杂对锂二次电池正极材料LiCoO2 体系的电子结构的影响 ,进而揭示Mg掺杂的LiCoO2 具有高电导率的机理 ,对Li(Co ,Al)O2 和Li(Co,Mg)O2 进行了基于密度泛函理论的第一原理研究 .通过对能带及态密度的分析 ,发现在Mg掺杂后价带出现电子态空穴 ,提高了电导 ,并且通过歧化效应 (disproportionation)改变了Co 3d电子在各能级的分布 ,而Al掺杂则没有这些作用 .O2 - 的离子性在掺杂后明显增强 . 相似文献

Co2FeAl0.5Si0.5 (CFAS)-based multilayers sandwiched by MgO layers have been deposited and annealed at different temperatures. Perpendicular magnetic anisotropy (PMA) with the magnetic anisotropy energy density Ku ≈2.5×106 erg/cm3 (1 erg = 10-7 J) and the coercivity Hc = 363 Oe (1 Oe = 79.9775 A · m-1) has been achieved in the Si/SiO2/MgO (1.5 nm)/CFAS (2.5 nm)/MgO (0.8 nm)/Pt (5 nm) film annealed at 300 ℃. The strong PMA is mainly due to the top MgO layer. The structure can be used as top magnetic electrodes in half-metallic perpendicular magnetic tunnel junctions. 相似文献
