The Allegory Study of Can Xue’s Novels [PDF]
, 2015 摘要 中国当代著名女作家残雪以其独特的写作方式和非凡的创造力驰骋于中国当代文坛三十余载，她的文学创作充满了奇幻诡异的想象和高度旺盛的生命活力。在种种鲜明特质背后，一直隐藏着的寓言性书写正是残雪小说文本中重要的基础性特质。借由寓言式表述总括和提炼，我们得以透视其小说背后的丰富哲思和人文精神。本文意图通过现代寓言批评理论，对残雪小说寓言式创作体系进行整体性探究。论文梳理了残雪寓言性小说创作的脉络，对其寓言书写的呈现方式与审美特质进行详细阐释。同时在阐释过程中着重挖掘其寓言书写的独特意义。论文主体分为七个部分，

带并联电抗器的交流特高压输电线路单相自适应重合闸故障识别方法
Gaoya dianqi, 2013 为使单相自适应重合闸避免重合于永久性故障,需对线路故障类型进行准确的识别。笔者针对带并联电抗器的交流特高压输电线路,计算瞬时性故障与永久性故障时中性点小电抗电压与故障线路端电压幅值比,分析发现,两种故障情况下其比值明显不同,因此利用中性点小电抗与故障线路端电压幅值比为判据,可准确判别瞬时性与永久性故障。大量ATP/EMTP仿真结果表明,该方法可以有效识别不同故障类型,且判别方法简单可靠性高。

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.
