摘要：The finite element system CAPA-3D was utilized as the numerical simulation platform,two structural FE models of orthotropic steel bridge decks were set up,the static and dynamic FE simulations under different loading conditions were carried out,the special attention was given to identify the critical wheel load location,and the maximum tensile stress distribution and the variation of strain rate inside membrane *** result shows that the FE models are capable of simulating the realistic behavior of orthotropic steel *** distributions of strains and stresses inside the surfacing materials depend highly on wheel load level,wheel load frequency,wheel position,membrane bonding strength as well as the thicknesses and characteristics of surfacing *** maximum tensile stress of membrane layers is found around 0.4MPa,which coincides with the minimum requirement for the adhesive bonding strength of membrane material proposed by the standards NF P98-282and *** maximum membrane strain rate is found around 0.1,which is an important information that can be utilized for the characterization of membrane products.1tab,28figs,7refs.

摘要：Significant transient beam loading effects were observed during beam commissioning tests of prototype II of the injector for the accelerator driven sub-critical （ADS） system, which took place at the Institute of Modern Physics, Chinese Academy of Sciences, between October and December 2014. During these tests experiments were performed with continuous wave （CW） operation of the cavities with pulsed beam current, and the system was configured to make use of a prototype digital low level radio frequency （LLRF） controller. The system was originally operated in pulsed mode with a simple proportional plus integral and deviation （PID） feedback control algorithm, which was not able to maintain the desired gradient regulation during pulsed 10 mA beam operations. A unique simple transient beam loading compensation method which made use of a combination of proportional and integral （PI） feedback and feedforward control algorithm was implemented in order to significantly reduce the beam induced transient effect in the cavity gradients. The superconducting cavity field variation was reduced to less than 1.7% after turning on this control algorithm. The design and experimental results of this system are presented in this paper.

摘要：出生于突尼斯的设计师tom Dixon,在1980年代中期崭露头角,被誉为＂未经后天栽培的焊铁家具设计天才＂。他曾加盟享誉国际的意大利家具生产商Cappel-lini,并设计了经典的＂S chair＂座椅。此次他受杨其龙先生的邀请设计TAZAMANIA BALLROOM，其结果令人惊艳。

摘要：抗氧剂是润滑油配方中的关键成分,通过有效地牺牲自身来保护润滑系统,即清除润滑油在使用过程中产生的自由基或分解氧化过程中形成的过氧化物,且抗氧剂在抗氧化反应中所产生的副产物不会对润滑体系造成不可控伤害。3,5-二叔丁基-4-轻基苯基丙酸酯(HPP)是位阻酚类抗氧剂的关键分子结构。在HPP衍生物中发现含有C8~C15烷基的化合物是理想的润滑油抗氧剂,如室温下是液态,非常便于在调配润滑油时使用,耐高温性能优异,且在各种试验条件下具有高效的抗氧化性能。抗氧剂和润滑油中其他成分的协同效应是理想商用抗氧剂的一种特性。二苯胺类抗氧剂和二硫代磷酸锌是两种常见的润滑油成分。在抗氧剂的评估过程中观察到,酚类抗氧剂与二苯胺类抗氧剂、二硫代磷酸锌均有显著的协同抗氧化作用,因为二硫代磷酸锌容易形成积炭而破坏汽车的催化转换器,润滑油工业界都在限制它的使用量。在积炭实验中发现,优化酚类氧化剂与二硫代磷酸锌的配比不仅可以减少二硫代磷酸锌的使用量,而且在最大限度减少积炭形成的同时显著提高润滑油抗氧化性能。

摘要：该项目是一座坐落于Hayden Avenue和National Boulevard街角的信息塔,其正对面是2011年6月通车的由洛杉矶市中心开来的Expo轻轨线路。这个交叉口是进入Culver City再开发区的主要入口。从概念上讲,这座信息塔同时具有内向与外向的设计目标。被新媒体公司、平面设计师和一般办公人员占用的场地面积不断扩张,在这片场地内,这座塔象征着城市发展的新方向,为当地的人们提供一处多变的艺术展示,将一系列关于区域内使用者当前和即将进行事件的图表和数据在五组高分辨率背投屏幕上显示出来。

摘要：在处理传统和现代化的问题上,英国的设计师们保持了审嗔的态度,他们一方面细心保存了历史,另一方面又始终保持前进的活力。英国人既离不开伊丽莎白女王,也需要贝克汉姆。作为一个设计大国,当代英国设计覆盖了生活的方方面面,从建筑到时装,从装置艺术到家居产品,从珠宝首饰到工艺陶瓷,无不显示出英国设计力量的活力与创新精神。

摘要：不起眼的纸板箱在我们的生活中随处可见,它们不仅可以在我们搬家时运送我们的财产,可以保护我们网购的商品不被损坏,甚至可以用来存储或在运输过程中放置几乎任何物品。就包装材料而言,由于纸板箱能够无限循环利用,因此具有令人难以置信的可持续性。然而,在上述的这些应用中,纸板箱只是配角。英国设计师马克斯·兰姆(Max Lamb)正在挑战这一观念,将纸板箱转变为一系列新的家具。
