Serrated flow has been primarily studied at the macron scale,yet the length and times scales at which the solute-meditated dislocation pinning and de-pinning processes that underlie the phenomenon occur are largely inaccessible by macroscopic ***,direct insights into the dominant slip systems in the serrated flow regime,which is particularly critical in Mg alloys given their high plastic anisotropy,requires the use of small-scale testing methods such as ***,in this work,a combination of microcompression and TEM based EDS/STEM measurements have used to critically study the temperature and strain rate dependences in single crystals of pure Mg and a Mg-Gd alloy oriented for twinning,basal-,prismatic-,and *** results provide compelling evidence that the solute drag mechanism underlie serrated flow in the alloy;they also show that serrated flow in Mg alloys is markedly *** anisotropy is caused by differences between the Burgers vector for slip/twinning,and between the impurity diffusivity along/perpendicular to the basal plane.

CEO(首席执行官)等领导要作出全面的决策,但做决策并不意味着回避员工的意见和想法。亨利·恩格尔哈特(henry Engelhardt)解释了如何在控制全局的同时征求员工意见。我曾强调过,优秀领导者的首要能力是决策能力,而要提高决策能力,就应该尽可能多地听取别人的意见,这就引出了领导力的第二个关键能力--善于与人打交道。那么,如何知道自己是否是个好领导?很简单,看员工是否愿意追随你。

创业型大学追求知识进步和知识资本化的双重目标。从大学使命的角度,创业型大学延伸了大学的传统使命,将教学、研究和为经济社会发展做贡献三大使命融为一体并彼此加强。从大学组织变革和内外相互作用的角度,创业型大学的发展基于知识资本化的生产逻辑,是“主体性”与“嵌入性”相互促进的过程。由此提出创业型大学发展“知识积累”“知识交换”与“体系驱动”三个阶段。根据三阶段特征,文章分析了创业型大学发展的七个核心要素,包括锚定创业战略方向、加强学术生产能力、培育师生创业精神、完善技术转移机制、生成新的混成组织、促进大学产业互动、营造创业生态系统。

Q1:您最初是从拍摄风光类照片起步的吗?为什么钟情于风光摄影?它给您带来什么收获?A:应该说我一开始并不喜欢摄影的,跟朋友们一起出游,如果里面有个爱摄影的朋友,他/她一定是那个拖大家后腿耽搁团队时间的家伙,所以我特烦这人(我后来开始摄影以后绝不拿着相机和非摄友一起游玩)。刚开始只是因为搬到加拿大来以后,为了让父母了解我们在异国他乡的生活状态,解老人的思念之情而拿起了相机,记录我们的生活并发回给国内的亲人。后来发现自己其实很喜欢摄影。刚开始第一年什么都拍,不仅仅是风景,也包括都市生活甚至这里逢年过节的社会活动,比如花街游行等等。

Earthquake Engineering and Engineering Vibration 2009年第4期8卷 521-536页

作者： henry C.Huang WSP Asia ltd.

After nearly a decade of application and investigation, a motion amplification device with viscous dampers for energy dissipation has been recognized as an effective solution to mitigate wind or seismic excitation, especially for stiff structural systems. As a result of compensation of amplified motion, it has been proved that the efficiency of viscous damper largely depends on the motion amplification device configuration, particularly for device stiflhess. In this paper, a ＂scissor-jack＂ type of motion amplification device, called a ＂toggle brace damper＂ system, is studied. It is demonstrated that the efficiency of such a device reflected by its amplification factor is not merely a function of its geometric configuration, but is highly dependent on the support elements＇ stiffness as well, similar to the mechanism of a leverage arm. Accordingly, a mathematical model in terms of complex modulus of the viscous damper with consideration of the support brace＇s stiffness is established. The results indicate that the efficiency of the motion amplification device with viscous dampers significantly depends on the stiffness of the support elements. Other parameters, such as toggle brace configuration and damping values of the viscous damper, are studied and compared. As an application example, numerical analyses are conducted to study the dynamic performance of a 39-story office tower installed with toggle brace dampers constructed on soft soil in a reclaimed area, under a combined effect of the vortex shedding of an adjacent existing 52-story building and earthquakes. The results show that viscous dampers with a motion amplification system using a properly designed toggle brace device proved to be an effective solution to alleviate the external excitations.
