日本被歧视部落女性是日本近代社会中最弱势的女性群体之一,在多重压迫体系的共同作用下,大量部落女性沦为近代公娼制度的牺牲品,她们的生存困境和生命创伤在主流话语的遮蔽下湮没无闻。1976年芥川文学奖的得主中上健次(1946-1992)就出身于日本和歌山县新宫市的被歧视部落,他通过建构“路地”文学世界重现了被日本近代文学所排除的被歧视空间,中上健次在多部小说中塑造了在近代公娼制度背景之下沦为娼妓的部落女性人物,有效填补了这一边缘群体的历史经验在日本文学史中的缺席,构成了修正国家叙事的对抗性话语。通过部落民娼妓人物的塑造,中上健次揭露了近代公娼制度背后权力机制的运作方式,表达出对遭受制度性性迫害的底层女性生命价值的肯定。

当特定能量的自由电子被原子核外电子轨道俘获时,有可能导致原子核被共振激发,这就是电子俘获致核激发.该机制的一个应用愿景是通过操纵电子使同核异能态所储存的核能按照人们的需求释放出来.如果能够实现这种技术,有望为核能的储存和利用带来巨大变革.本文对比了近年来基于加速器装置,在高电荷态离子阻停过程中测量电子俘获致核激发几率的两次实验研究工作.对于两次测量结果的不一致,从误差水平评估这一个新的角度分析了可能的原因.此外,通过评估四种可能的熔合蒸发反应道,发现94Zr束流和氦气靶可能是利用次级束开展下一步实验工作的理想弹靶组合.
