Designers and artists have always looked to nature for inspiration and materials, but only recently they have been able to alter and incorporate living materials and biology in their work. A study was conceived for fashion to be grown directly from natural renewable bio-material which was more labour friendly, cost effective and of a lower environmental impact. A new design framework of fashion creation from natural renewable bio-material was established to reason the design rationale and procedures for optimal results and efficiency. The experimentation involved cellulosic formation from its solution to 2D, to 3D form, to multiple 3D form. This paper reported prior examples of art and design that involved natural self-grown materials and techniques, meanwhile, observed and analyzed their feasibility for future development.

Abstract: 英语缩略语由于顺应了人们生活中的“经济原则”而大量嵌入到汉语中,并引起了学者的研究兴趣。本文以都市类报纸中嵌入英语缩略语的中文广告语篇为语料,找出使用频率较高的英语缩略语,并对这一语言现象从模因概念、周期以及语用效应的角度探讨其成为强势模因的动因及其产生的语用功能,从一个新的角度揭示英语缩略语在汉语中存在的理据
 

English abbreviations have been largely embedded into Chinese since they apply with the “principles of economy” in life, and they are of interest to researchers. By making an investigation into the data of Chinese advertisements embedded with English abbreviations from popular newspapers and based on the theory of memetics, the present paper hopes to find out the English abbreviations frequently used in the ads, discusses how some abbreviations become powerful memes and probes into their pragmatic effects, so as to provide the rationale for the existence of English abbreviations in Chinese from a brand perspective.

地缘结构视角下中国西北部地缘环境与国家安全

 [PDF]

曹原,
Geographical Science Research (GSER) , 2015, DOI: 10.12677/GSER.2015.42008
Abstract:
我国周边地缘结构复杂。我国西北部毗邻广阔的中亚地区。中亚地区多民族、多文化交叠,对我国国家安全构成一定威胁;同时,中亚地区对保障我国能源供给起着十分重要的作用。近年来,美国中亚南亚政策的调整、大国在这一地区的“博弈”、经济领域的侵害、文化领域的渗透、“三股势力”的活动等,严重影响我国的国家安全。为了应对这一局势,我国要借助“上海合作组织”这一多边合作平台,加强与各相关国家的合作,防止“东突”势力与国际反华势力、“三股势力”暗中勾结,破坏中国与中亚国家的关系。防止大国在中亚的军事争夺演化成对中国的直接安全威胁。积极参与中亚石油生产和经营活动,避免中亚形势发展对中国能源安全造成重大冲击。发挥新丝绸之路的地缘战略价值,坚持中国的西部开发、开放和发展,辐射带动中亚地区的振兴和繁荣。加强与俄罗斯的睦邻友好关系,利用两国地缘上毗邻的有利条件,背靠对方,形成地缘政治合力,以对付共同面临的各种问题和威胁,争取最大的战略回旋余地和安全利益。加强与邻国的和平地缘外交,维护邻国的稳定,构筑中国的和平安全环境。
Geo-structure surround China is complicated. The Northwest China adjoins the wide, multi-ethnic and multi-cultural blended Central Asia which is the threat situation to China. In the meantime, Central Asia plays a very important role in guaranteeing China’s national resources supply. In re-cent years, the changes of American strategies, “game playing” between other great powers and terrorist activities in this area badly affect China’s national security. In order to response this sit-uation, first, we should strengthen cooperation with related countries with the help of Shanghai Cooperation Organization in order to promote the relationship with Central Asian countries; second, build effective cooperation mechanism against terrorist activities with surrounding countries; third, join oil production and management in Central Asia actively. From inside of our country, we should develop geo-strategic value of the New Silk Road to promote the development in West China and association between West China and its neighbor countries. Also, we should consolidate the relationship with Russia to formulate resultant force in this area and the world to strive for national security interests.

Abstract:
黄本立院士及其所在的科研团队在质谱领域做了大量的开创性的研究工作,若干工作在国内外起到了引领作用。在仪器研制方面:1) 样品离子引入与飞行路线正交,避免不同元素动能对分析的影响;2) 采用飞秒级极窄脉冲和7 × 1013 W/cm2高辐照的激光器,大大减少基体效应和元素的分馏效应;3) 用氦作缓冲气体,适度冷却等离子体及避免周围空气的卷入,降低多价离子和多原子离子的干扰,获得明晰的谱线和清晰的背景;这些改进使质谱技术的分析性能达到前所未有的高度,如分辨率达7000,检出限达10?6~10?7 g/g,覆盖6~7数量级的动态范围。为等离子体的基础研究和质谱广泛的应用奠定了坚实的基础。在基础研究方面:1) 激光诱导等离子体离子动能分布研究,获得了等离子体形成和发展动力学知识;2) 探索激光诱导等离子体温度与激光波长、脉冲宽度、激光能量、辅助缓冲气体压力和样品硬度等之间的关系,为获取最优的分析性能提供了理论依据;3) 辅助缓冲气体离子源的研究,有效地降低离子的动能和多价离子的干扰。4) 建立飞行时间质谱仪二维分离技术,通过离子的初始动能及其质荷比的不同实现二维分离,实现了把分析物离子从多价离子和气体类离子中分离出来。在应用方面,把质谱分析技术应用范围扩大到前所未有的广度,若干应用具有里程碑意义:1) 半定量无标准固体中金属和非金属元素的直接分析;2) 古瓷碎片分析;3) 薄层剖面分析;4) 形态分析;5) 矿物分析;6) 有机化合物分析;7) 生物样品分析。
Academician Huang Benli and his research group have done a lot of groundbreaking research work in the field of mass spectrometry, some of which are pioneer works in the world. The pioneer works in the instrument design include: 1) Orthogonalizing the introduction of the sample ion and flight routes to avoid the influence of the kinetic energy for different element on the analysis; 2) using pulses laser with several femtoseconds (fs) width and 7 × 1013 W/cm2 of high irradiation to reduce the matrix effect and the fractionation effect of elements; 3) using helium as buffer gas to moderate cooling plasma and avoid the involvement of the surrounding air, which reduce the interference of multiply charged ions and polyatomic ions and obtain an explicit spectrum and clear background. Due to these works, the performance of mass spectrometry analysis reached an unprecedented height. For instance, the resolution reached 7000, the detection limit reached 10?6 - 10?7 g/g, and the dynamic range covered 6 - 7 orders of magnitude. A solid foundation has been thereby established for the basic research of plasma and the wide application of mass spectrometry. Furthermore, they also made great achievements in the fundamental research, including: 1) the study of ion kinetic energy distribution in the laser induced plasma developed the knowledge theory of dynamics of the plasma formation and expansion; 2) the exploration of the relationship between the laser induced plasma temperature and the laser wavelength, laser energy, pulse width, auxiliary buffer gas pressure and the sample hardness etc., provided the theoretical base for obtaining the optimal analysis performance; 3) the study of auxiliary buffer gas ion source for effectively reduced the ion kinetic energy and the
