针对高浓度聚驱采出液油水分离效率及其给常规交直流电场带来的冲击,开展了该类采出液的乳化行为及脱水方法研究,研究中综合了集输工况条件下的采出液转相特征、电负性、乳化油珠粒径分布、界面性质、乳化体系的微观形态及瓶试法油水分离实验,并基于所建立模拟装置评价了脉冲供电脱水对高浓度聚驱采出液破乳脱水的适应性。结果表明,高浓度聚驱采出液复杂的乳化行为与含聚浓度直接相关,含聚浓度上升使其电负性增强,转相点呈不同程度降低,且由于促进了黏弹性界面膜的形成,乳化粒子聚并和相分离的难度增大;辅以化学破乳的脉冲供电电场脱水工艺能有效改善分离效果,提高脱水操作的稳定性。

前人研究发现个体的权力感会增强或减弱消费者的送礼行为。本文试图解决以往研究中的分歧,基于情境聚焦理论考察中国文化背景下关系取向如何调节权力感对送礼行为的影响及其内在作用机制。通过两个研究发现:公共关系取向下,高(vs.低)权力感消费者更倾向于开展送礼行为;交换关系取向下,高(vs.低)权力感消费者较少倾向于开展送礼行为。而且,送礼感知(即感知愉悦和感知回馈)在不同关系取向下权力感对送礼行为的影响中发挥中介作用。本文从情境聚焦理论的视角辨析了权力感对送礼行为发挥影响的边界作用条件,整合了不同文献证据间的对立观点,具有重要的理论贡献。同时,本研究对中国文化背景下送礼消费的营销宣传和广告策划都具有实践意义。

笔者试图从个人身份认同这一角度,分析泰戈尔短篇小说《活着还是死了》中女主人公迦冬比妮在内心机制和外在环境交融下产生的身份认同的异化,以及在这场身份认同中"他者"始终占据上风,排挤"自我"。进而进一步揭示异己身份的深刻社会内涵。
