基于关系美学的红色陶瓷文创设计研究

党的十八大以来，习近平总书记多次就“保护红色文化、传承红色基因”进行阐释和论述，反复强调与确保红色血脉永庚续，红色基因代代传。鉴于此现状，对“红色文化”进行了研究，以关系美学作为研究的切入点，建构基于关系美学的“红色”陶瓷文创产品互动化、体验化的设计方法，执持把中国红色文化传承好的态度，思考多元融合的陶瓷文创设计原则。以此传承红色记忆，创新红色陶瓷文创产品内容，让红色文化走得更远。

谁是真正的恐怖分子

木材,简直是最常见的材料。几乎同样的木材妙构想,巧手雕琢,将呈现怎样纷繁多样的变化？作品的背后,还有什么我们难以想象的深刻含义？纽约艺术与设计博物馆今年推出的木材料艺术特展,提供了当代木材的90种面貌,展示了世界各大艺术家和设计师的超凡想象力。如憨态可掬的母鸡身上暗藏成千上万根火柴;鸟笼做成的凳子：全木料的时尚高跟鞋：盖着反恐印章又布满弹孔的木质相框……     

爬进椅子的洞

设计不只是用来观赏或使用,更重要的是,设计与人之间的互动。诡异的形状、浑浊的颜色,这把椅子真谈不上具有美感!它旁边还有个大洞,干嘛用？年轻的西班牙设计师纳科·卡博内尔笑了：＂哦,你可以爬进去,暂时避避现代生活的‘恐怖袭击＇!＂幽默、富有想象力是纳科的个性,正如这把椅子,将洞穴和坐具结合,让人们在惊艳的同时,感受到犀利的批判力,从而引发对现实的思考。

[达人玩手工]“2008&#183;创意手工”参赛作品选登（之四）：幸福是“杂货”的味道

他们可以是学生．也可以是设计师；可以是旅行者。也可以是商人。他们身份多变，却有一个共同点：玩创意．爱手工。小到印有自己LOGO的各种小物、大到改装一条牛仔裤。或是背包坐遍全城的公交车．再把路线绘制出来……在他们眼里。总有想不到的惊喜．在他们手里，总能化平凡为神奇。     

穿梭在云间

是否还记得10多年前那部《云上的日子》，电影里的4篇爱情故事切换着时空和地点，配合着忧郁而轻柔的曲调，让人好像置身于迷雾般的云层中。如果在云间穿梭，想来应该就是那种软软的、暖暖的感觉吧!

Studies of IR‐Screening Smoke Clouds

This paper contains some results of research on the IR‐screening capability of smoke clouds generated during the combustion process of varied pyrotechnic formulations. The smoke compositions were made from some oxygen or oxygen‐free mixtures containing metal and chloroorganic compounds or mixtures based on red phosphorus. The camouflage effectiveness of clouds generated by these formulations was investigated under laboratory conditions with an infrared camera. The technique employed enables determination of radiant temperature distributions in a smoke cloud treated as an energy equivalent of a grey body emission. The results of the analysis of thermographs from the camera were the basis on which the mixtures producing screens of the highest countermeasure for thermal imaging systems have been chosen.     

2002年CD-R产品:技术市场风起云涌

在CD-R产业经过1999年～2000年的高速发展之后,虽然2001年CD-R产业进入了调整期,但是CD-R产品的需求仍保持相当速度的增长。根据最新的消息显示:台湾莱德公司为了保持其在行业中的龙头地位,现在已经开始利用其规模优势,再次以较低的价格冲击CD-R市场,欲将小的生产商清除出局。对于中国的CD-R生产企业,我们最大的优势在于:我们购置设备较晚,设备的价格比较低廉,同时设备的生产效率比较高。同周边地区的生产企业比较,这些企业引进设备的时候,价格在80O万/复制头,而我们引进的时候价格已经下降至300万/复制头,生产周期也从6秒下降到4.5秒。可以说我们是轻装前进,周边企业是负重而行。同时随着2001年后CD-R产业结构重新洗牌的趋势越来越明显,中国的企业是否能抓住这个机会对将来整个光盘产业的演变具有深远的意义。     

Particle Generation and Resuspension in Aircraft Inlets when Flying in Clouds

Using on-line analysis of single particles, we have observed both generation and resuspension of particles when ice crystals, cloud droplets, or dust impact an aircraft inlet. Large numbers of particles smaller than 1 μ m with a composition suggesting stainless steel were measured when flying a stainless steel inlet through cirrus clouds. Smaller numbers of metal particles were also observed when flying through dust or water clouds. A different instrument, sampling through a different inlet, found zinc particles when sampling in cirrus clouds. Laboratory experiments have verified that high-speed ice crystals can abrade stainless steel. Collision of ice crystals with the inlet wall also resuspended previously deposited particles. A notable example came when a flight through the space shuttle exhaust plume deposited large numbers of unique particles in our inlet. Some of the same types of particles were observed when the aircraft flew into an ice cloud the following day. The generation of particles by impaction of ice crystals and dust in inlets may have affected some published results about ice nuclei and metal particles in the upper troposphere. The newly generated particles cannot be distinguished from atmospheric particles by size alone.     

Computational Analysis of Injection-Velocity Effects on Dynamic Parameters of Unconfined Fuel-Vapor Clouds

A computational investigation is performed to study the effects of injection velocity on the main dynamic parameters of the fuel cloud released into the open atmosphere. The volume, shape, and growth rate of the cloud, turbulence intensity, as well as the distribution of fuel concentration, temperature gradient, and self-ignition induction time are the most important parameters determining the mode of combustion that propagates through the cloud. A modified KIVA-based program is employed to fulfill the calculations. Systems of equations are solved by a finite-volume method. The k-ɛ model and discrete droplet model are applied for modeling gas-phase turbulence and liquid spray, respectively. The fuel-injection velocity is shown to have a major effect on turbulence intensity and uniformity of the cloud. With increasing injection velocity, the detonable part of the cloud rotates sooner and faster, and there is less time for ignition. A comparison with experimental results is performed for validation. __________ Translated from Fizika Goreniya i Vzryva, Vol. 41, No. 5, pp. 29–40, September–October, 2005.
