摘要：A rigorous back analysis of shear strength parameters of landslide slip was presented. Kinematical element method was adopted to determine factor of safety and critical failure surface, which overcomes the disadvantage of limit equilibrium method. The theoretical relationship between the combination of shear strength parameters and stability state was studied. The results show that the location of critical slip surface, F/tan f and F/c depend only on the value of c/tan f. The failure surface moves towards the inside of slope as c/tan f increases. According to the information involving factor of safety and critical failure surface in a specific cross-section, strength parameters can be back calculated based on the above findings. Three examples were given for demonstrating the validity of the present method. The shear strength parameters obtained by back analysis are almost consistent with their correct solutions or test results.

摘要：To address the issues of reduced graphene oxide(RGO) dispersion in copper(Cu) matrix and interface bonding between RGO and Cu, an electrostatic adsorption method with interface transition phase design was employed to prepare the RGO/Cu based composites. Cu-Ti alloy powder was employed to improve the combination by forming carbides at the RGO-Cu interface. It was noted that the mechanical property of 0.3 wt.%RGO/Cu-Ti composite was increased by 60% compared with that of the matrix. Strengthening mechanism analysis suggested that the enhancement of the mechanical property was ascribed to the load transfer and second phase strengthening which were from the improved dispersion of RGO and the in-situ formed titanium carbide phase.

摘要：标志是一种大众传播符号,它以各种精炼的形象表达一定的涵义,传达明确而特定的信息。因此标志也是一种寓意的象征符号,即"有意味的形式",标志的这种功用最终是取决于标志的创意和视觉表现上,本文就从标志设计的发展和视觉表现等方面来探讨标志设计的创意与视觉语言的生成。

摘要：基于当前时代人际交互多样化的背景,在艺术创作领域中,互动性设计不仅是对人际交互问题的一种可靠的解决办法,也是对人际交互形式更为生动形象的一种表达方式,进而予设计创作以启发。本文以艺术设计领域的互动设计为研究对象,将其立足于材料、形式、功能三个大方向进行探讨,挖掘互动设计的基本方式,并将其运用在首饰设计创作中。本文所研究的互动首饰设计是基于心理学中的分支,精神分析学的理论之上,探讨如何运用拉康镜像理论来支撑互动首饰设计,以首饰为媒介来反映当下的社会问题及其本质,通过首饰的形式来对设计的主题进行艺术性的表达,力求动态展现出主题所针对的人际互动关系本质。旨在拓宽首饰的功能性,并在新的人际交互主题下对互动首饰设计的形式加以创新。

摘要：The spin-dependent electronic transport properties of a zigzag zinc oxide(ZnO) nanoribbon are studied by using density functional theory with non-equilibrium Green's functions. We calculate the spin-polarized band structure, projected density of states, Bloch states, and transmission spectrum of the ZnO nanoribbon. It is determined that all Bloch states are located at the edge of the ZnO nanoribbon. The spin-up transmission eigenchannels are contributed from Zn 4s orbital,whereas the spin-down transmission eigenchannels are contributed from Zn 4s and O 2p orbitals. By analyzing the current-voltage curves for the opposite spins of the ZnO nanoribbon device, negative differential resistance(NDR) and spin filter effect are observed. Moreover, by constructing the ZnO nanoribbon modified by the Zn-edge defect, the spin-up current is severely suppressed because of the destruction of the spin-up transmission eigenchannels. However, the spin-down current is preserved, thus resulting in the perfect spin filter effect. Our results indicate that the ZnO nanoribbon modulated by the edge defect is a practical design for a spin filter.

摘要：二十世纪六十年代,女性主义思潮的出现促使男女性别平等、含混的观念在文学、戏剧、美术等领域涌现,进而引发艺术领域的创作思维模式变得更加丰富。基于此背景,“性别含混化”逐渐成为人们重视的概念及社会现象,为艺术创作带来了一个全新且独特的研究视角。与此同时,这也为性别研究提供了理论契机,其理论随着女性主义的流派发展而丰富,但是涉及的实践研究略为单薄。文章基于性别研究(Gender Study),将“性别含混化”观念与理论与当代首饰创作实践相结合,意在给首饰设计带来新的研究视角、表现形式与媒介,拓宽首饰的创作思维,使首饰语言更加多元化。

摘要：追溯传统首饰创作思想,时间与空间一直是客观存在的概念,首饰所反映的此类议题始终停留在实用功能层面。然而,在极具观念性变革意味的“当代性”进程中,身体成为首饰创作中最为突出的问题,引发首饰领域掀起了构建身体与首饰多元化关系、推崇观念至上的艺术浪潮,从而促进了“当代首饰”的生成。以梅洛-庞蒂为代表的学者,基于知觉现象学视角提出了身体是最原始的空间与时间,二者概念的形成皆是建立在身体层面上的观点。这种以身体为参照,打破传统观念中遮蔽身体存在的时空观,促使首饰创作形成了以凸显身体知觉感受为核心的当代转化。

摘要：楚人在长期的生产劳动实践中创造和发展出了灿烂的文化,更以深厚的文化底蕴和造物智慧积淀出独树一帜的物质文化遗存与制器思想,而各类器物中尤以青铜器的成就最高。本文基于此,分析归纳了楚式青铜器的三种文创设计转化方法:器形纹饰的提取与凝练、历史典故的解读与应用和文物活化的转换与诠释,阐述具体产品的显性特点以及深层的文化内核,对其设计转化方法进行分析,以期为传统文物“活起来、火起来”提供新思路、新方法,激发更多设计人才创造具有民族文化风格的文创产品,拉近广大人民群众与文物的距离,并从中体悟中华文化,增强文化自信和民族自信。

摘要：飞机结构设计与强度分析是影响飞机结构安全的关键因素,从静强度到安全寿命、损伤容限理念的提出,再到耐久性概念和结构完整性规范的形成,经历了飞机设计理念和技术体系不断完善的过程。然而,目前结构完整性理念在工程实际中的贯彻仍停留在产品研制和检测的层面,限制了其更深层次的作用。介绍了飞机结构设计从静强度设计到结构完整性设计的发展历程、飞机结构完整性的基本概念和飞机结构完整性大纲(ASIP)的主要特点;通过"5个任务",突出了结构完整性大纲从传统设计阶段的分析和检测规范到产品全生命期的过程控制与管理规范的提升转变;最后通过2个典型型号案例,介绍了飞机结构完整性理念在设计、验证与使用维护全生命期的成功应用。通过对基本概念的剖析以及对主要设计理念发展的梳理,展示了飞机结构安全策略从设计研制阶段到全生命期控制的质变过程,指出了结构完整性理念从基于试验的体系方法向着数字化方向发展的趋势。
