REMg8.35Ni2.18Al0.21 （RE=La, Ce, Pr, and Nd） alloys were prepared by induction melting and following annealing. X-ray diffraction （XRD） and scanning electron microscopy （SEM） results showed that the alloys were composed of Mg2Ni, （La, Pr, Nd）MgzNi, （La, Ce）2MgxT, （Ce, Pr, Nd）Mg12 and Ce2Ni7 phases. The above phases were disproportioned into Mg2NiH4, MgH2 and REHx （x=2.5 1 or 3） phases in hydriding. CEH2.51 phase transformed into CEH2.29 phase in dehydriding, whereas LaH3, PrH3 and NdH3 phases re- mained unchanged. The PrMg8.41Ni2.14Al0.20 alloy had the fastest hydriding kinetics and the highest dehydriding plateau pressure while the CeMg8.35Ni2.18Al0.21 alloy presented the best hydriding/dehydriding reversibility. The onset hydrogen desorption tempera- ture of the CeMg8.35Ni2.18Al0.21 hydride decreased remarkably owing to the phase transformation between the Cell2.51 and the CEH2.29.

房山石经题记中唐代社邑首领的几个问题

房山石经题记中记载的社邑首领名称不一,出现较多的有邑主、社官、平正、录事等。从石经题记来看,平正应为社官之别名,平正与社官非两种社中官职。社官和邑主分别源自两个系统,担任者的身份也有很大差异。维那在房山社邑中出现次数很少,说明在幽州地区此称谓不甚流行,其地位也与论者的某些说法不完全一致。房山社邑首领以二人组合为多,还有部分单独出现的,三官组合较少,说明房山社邑首领还没有像唐末五代时期的敦煌私社那样固定为三官。这与刻经社邑功能单一有关。与东晋南北朝时期佛社相比,房山社邑首领名称由繁杂多样而趋向集中固定。这些称谓一部分源于东晋南北朝时期的佛社首领,更多则来自唐代官社和政府官职的影响。

作者：贾艳红天津师范大学古典文献研究所天津300387

战国秦汉时期,巫觋的社会地位呈日益下降之趋势。这主要是因为巫觋集团对王权的依附性,使中国的巫没有象西方的祭祀集团那样走向独立,发展到可以与王权分庭抗礼的程度,而是随着王权与神权的衰落一并衰落了;巫对文化知识垄断权和祭祀垄... 详细信息

战国秦汉时期,巫觋的社会地位呈日益下降之趋势。这主要是因为巫觋集团对王权的依附性,使中国的巫没有象西方的祭祀集团那样走向独立,发展到可以与王权分庭抗礼的程度,而是随着王权与神权的衰落一并衰落了;巫对文化知识垄断权和祭祀垄断权的丧失,使其逐渐远离神权中心和政治中心,开始向民间滑落;巫觋自身素质的下降在很大程度上削弱了这一职业的神圣性,也进一步降低了他们在人们心目中的地位。

信仰是早期人类面对大自然的严酷而感到自身软弱无力的必然产物。在自然和社会的双重压迫下,人们感到恐惧,依靠个人力量难以与大自然和社会压迫的强大力量抗争,这就促使人们产生对超现实力量的信仰,幻想借助于超自然的神力来消除恐惧,摆脱苦难与困境,实现依靠人力难以实现的目的。祈福避祸的心理需求则成为信仰产生的深层底蕴。
