摘要：克里斯蒂安·佩措尔德是当代德国影坛最重要的导演之一,他的作品观照社会现实,惯常表现面临诸多生存困境、漂泊于德国街头的边缘个体。在他的影像中,传统意义上的“地点”常常缺席,取而代之的是一个个充当过渡空间之用的“非地点”。这些“非地点”作为叙事空间具有丰富的意涵:一方面,佩措尔德导演通过它们回望德国战时对“地点”的湮灭;另一方面,战后德国的重建与现代化进程的加速导致大量“非地点”的涌现,这些空间隐喻了影片角色不稳定的生存处境及心理状态。随着现实语境的变化,佩措尔德导演近年来也通过“非地点”的影像呈现表达出对全球紧迫议题的关注。栖身“非地点”中的人们怀有对救赎的渴望,佩措尔德导演的一些作品表现出在“非地点”上进行重建的可能,带来了富有深意的人文关怀与视听想象。

摘要：面对弹道修正引信中光学组件无法承受弹丸高发射过载的迫切需求,针对某型制导炮弹成像引信光学系统,结合仿生理念提出一种引信光学系统减振方案。将竹子的宏微观结构应用于金属薄壁管,为光学系统设计两种具有竹子结构特征的金属薄壁套筒,并同时设计由橡胶垫与碟簧复合的减振装置。利用有限元分析软件进行动力学仿真验证设计结构模型的减振效能。仿真结果表明:所提减振方案能够缓解光学系统受到的冲击并降低变形值,两种透镜外筒应变峰值降低40%、72%,光学传感器应变峰值降低68.21%、52.49%,证明该减振方案具有良好的减振效果。所提方案为光学部件在高过载引信中的应用提供新思路。

摘要：The sensing capabilities of a soft arm are ofparamount importance to its overall performance as they allow precise control of the soft arm and enhance its interactionwith the surrounding environment. However, the actuationand sensing of a soft arm are not typically integrated into amonolithic structure, which would impede the arm’s movement and restrict its performance and application scope. Toaddress this limitation, this study proposes an innovativemethod for the integrated design of actuator structures andsensing. The proposed method combines the art of kirigamiwith soft robotics technology. In the proposed method, sensorsare embedded in the form of kirigami structures into actuatorsusing laser cutting technology, achieving seamless integrationwith a soft arm. Compared to the traditional amanogawakirigami and fractal-cut kirigami structures, the proposedmiddle-cut kirigami (MCK) structure does not buckle duringstretching and exhibits superior tensile performance. Based onthe MCK structure, an advanced interdigitated capacitivesensor with a high degree of linearity, which can significantlyoutperform traditional kirigami sensors, is developed. Theexperimental results validate the effectiveness of the proposedsoft arm design in actual logistics sorting tasks, demonstratingthat it is capable of accurately sorting objects based on sensorsignals. In addition, the results indicate that the developedcontinuum soft arm and its embedded kirigami sensors havegreat potential in the field of logistics automation *** work provides a promising solution for high-precisionclosed-loop feedback control and environmental interaction ofsoft arms.

摘要：老舍在小说《骆驼祥子》中对常规语言进行变异,从而实现了文学语言的陌生化。研究从声响形态变异的角度,结合变异修辞学理论,对小说中摹音层面与谐音层面的语言变异现象进行定量与定性分析,发现摹音变异在文本中占据主要地位。通过进一步探讨声响形态变异在塑造人物性格、渲染环境氛围以及表现事物特质方面的修辞效用,阐明了老舍对传统京味曲艺的深刻吸纳及其独特的文学语言观念。研究表明,《骆驼祥子》的声响形态变异利用语言符号能指与所指之间的有机联系,实现了文学语言的陌生化表达,这不仅拓展了《骆驼祥子》语言艺术研究的视野,深化了对声响形态变异作为修辞现象的理解,还对解析老舍文学语言风格及其文学创作的时代价值具有重要意义。

摘要：为了设计和开发具有绿色、环保高阻燃效率的EP阻燃剂,以SAPO及Fe(NO_(3))_(3)·9H_(2)O、Bi(NO_(3))_(3)·5H_(2)O为原料,设计合成了两种水杨醛基席夫碱金属化合物SAPO-Fe、SAPO-Bi。研究了它们对EP复合材料热稳定性能和阻燃性能的影响,并探究相关阻燃机理。结果显示,EP/6%SAPO-Fe、EP/6%SAPO-Bi的垂直燃烧测试通过UL 94 V-1等级;LOI值分别提升20.6%和16.2%;p HRR值降低28.6%和34.8%;THR值降低30.8%和14.2%;与EP相比,残炭量分别增加了74.1%和112.9%;TSP值降低了40.4%和38.9%;PCOP值降低44.4%和50%。阻燃性能的显著提升主要得益于P、N元素与金属离子Fe^(3+)、Bi^(3+)的协同效应;残炭量的显著增加以及烟气释放的有效降低,归因于这些金属离子卓越的催化成炭能力,形成致密的炭层增强物理阻隔效果,从而有效阻止烟气的产生、可燃气体的逸出、氧气的进入以及热量的释放。
