浅析静载试验的技巧

桩基础由于具有抗震性能好,沉降量小和承载力高,可以解决特殊地基土的承载力的优点,越来越受到人们的青睐。文中通过静载试验得到几点体会。     

桑车后制动鼓化学成份的控制

以德国大众汽车公司ＴＬ－ＶＷ０１１标准为依据，通过对１９９６年１～５月大量数据的类比分析、正态分析和回归分析等数理方法，寻找桑车后制动鼓的化学成份与机械性能、金相组织之间的关系，并严格控制熔炼工艺，从而使其金相组织、楔压强度、硬度的报废率从１４．３％降低至１．１１％．

Solid Freeforming and Combinatorial Research

A view of manufacturing processes is presented in which five distinct categories are defined as casting, deformation, machining, joining, and solid freeforming. Solid freeforming is essentially biomimetic and shares problems of morphogenesis with natural processes. Our team in University of London has been exploring three mechanisms of solid freeforming. In dry powder deposition and direct ink-jet printing, the emphasis has turned to the problem of delivering a complex shape in which the three dimensional spatial arrangement of composition is delivered from the design file. In extrusion freeforming, the aim is to control microstructure at hierarchical levels also from the design file. The quest for 3-D functional gradients is satisfied by acoustic and ultrasonic dispensing and mixing of powders so that each layer can be patterned. These methods could be extended to deliver the complex patterns demanded by left-handed microwave metamaterials. Dry powder deposition and direct ink-jet printing are turning towards combinatorial methods in which multiple sample libraries are used to accelerate discovery. In turn, this paves the way for ’autonomous research machines’ which steer their own search refinements in response to our requests for new materials. In this way, solid freeforming used for sample preparation can give an ’arm’ to an intelligent machine so that it can conduct its own experimentation and learning; an idea that originated with Alan Turing in the late 1940s.     

德·狄维士:与中国双赢

最有意思的是,我们为了解决问题,我们在考虑,中国政府关注哪些问题的时候,中国的监管机构也在想我们是什么样的业务,也在研究我们。狄维士认为,企业与监管部门如果能保持双赢的态度探讨行业发展方向,将会带来最好的结果。本次演讲中,狄维士不仅讲了对中美双边贸易的理解,更重要的是分享了安利与中国直销监管者的沟通经验。
