摘要：深层页岩天然裂缝与层理缝发育,经体积改造后易形成“主缝+支缝+次微缝”的多级裂缝结构,但受高垂向应力和高水平应力差条件的影响,深层页岩压裂裂缝开度极窄且主次缝开度差异较大。为了明确多级裂缝内支撑剂运移机制与分布规律,搭建了大型可视化支撑剂输送实验系统,研究了泵注排量、液体黏度、支撑剂粒径、支撑剂浓度、裂缝特征参数对支撑剂运移与分布的影响规律,最后基于水电相似原理计算了裂缝整体导流能力并开展了评价分析。研究结果表明:①缝内支撑剂存在多种堆积模式,其形成由流体对支撑剂的携带能力决定;②支撑剂分流效率受多种因素影响,增大排量与减小支撑剂粒径均可提高分流效率;③多级裂缝内,增大排量与压裂液黏度均在一定程度上改善了支撑剂非均匀分布,但裂缝导流能力表现为先增大后减小;④综合支撑剂分流结果与多级裂缝内支撑剂分布规律,推荐坚持“大排量+低黏度”泵注思想,以保证大粒径支撑剂占比,适当混合小粒径支撑剂,构建“近井区高导流+远井区有支撑”的高导流裂缝体。结论认为,基于含多级裂缝的大型可视化支撑剂输送实验系统,全面系统研究了不同条件下多级裂缝内支撑剂运移与堆积的模式,研究成果可为深层页岩压裂泵注工艺参数设计与优化提供理论支撑。

摘要：For low power dielectric barrier discharge （DBD） used in small-size material treatment or portable devices, high- step transformer parasitic capacitance greatly influences the performance of the resonant converter as it is of the same order of magnitude as the equivalent capacitance of DBD load. In this paper, steady-state analysis of the low power DBD is presented, considering the inevitable parasitic capacitance of the high-step transformer. The rectifier-compensated first harmonic approxi- mation （RCFHA） is applied to linearize the equivalent load circuit of DBD at low frequency and the derived expressions are accurate and convenient for the analysis and design of the power supply. Based on the proposed linear equivalent load circuit, the influence of transformer parasitic capacitance on the key parameters, including the frequency range and the applied electrode voltage, is discussed when the power is regulated with pulse frequency modulation （PFM）. Also, a design procedure is presented based on the derived expressions. A prototype is constructed according to the design results and the accuracy of the design is verified by experimental results.

摘要：巴西籍犹太裔哲学家威廉·弗卢塞尔曾提出建构一种“设计哲学”的设想,它存在着日用品设计与纯粹“设计”两个阶段与面向。在日用品设计层面,弗卢塞尔使用现象学方法去还原日常生活用品,使其展露出其本来面貌。而在纯粹“设计”理念层面,他考察了从柏拉图到数字时代的设计概念,认为设计正在走向非物质性与“形式”本身,这预示着设计“极权主义社会”的到来。

摘要：“异类幻化”情节是华语魔幻类型电影中最具有吸引力、商业性和悸动性的影像画面之一。本文从“概念整合理论”出发,提出了“异类幻化”数字特效设计的概念整合模型。叙事认知整合、视觉审美整合、文化创新整合是电影的一体三面,分别在奇情之美、神异之美和共生之美的身体重构中发挥着重要作用。在类型电影中,将概念整合理论与数字特效设计的创意实践相结合,不仅能更深入地揭示从文本故事到数字影像转化的创造性思维活动,也能对华语魔幻电影构建具有东方技术美学风格的影像创作有着检视和参考的现实作用。
