The frame has decreased the maximum deformation by by 60% and increased the fundamental frequency by 65% as compared with those of aluminum alloy materials  a new type of aeronautical material-particulate reinforced aluminum matrix composite (SiC/Al composite) is investigated. Several crucial technologies  respectively as shown by finite element analysis results. Those are confirmed by vibration test furthermore. Therefore  such as pressureless infiltration technology  a significant lightening effect is achieved and the thermal control load is also reduced. The test result indicates that the stable accuracy of the system achieves 19.8rad and the optical-axis parallelism of pay load is 0.1mrad. The research applies the SiC/Al composites to airborne photoelectric platforms  interface reaction controls and plate's welding are systematically studied. Then  which makes a effective exploration for the new aeronautical material's application. 2011 IEEE.  using SiC/Al composites  the airborne photoelectric stable turret frame is successfully prepared in density of 2.94 g/ cm3   A dynamic data mining model for engineering management (EI CONFERENCE) 会议论文 2009 Second ISECS International Colloquium on Computing, Communication, Control, and Management, CCCM 2009, August 8, 2009 - August 9, 2009, Sanya, China Zhu J.-W.; Tang Y.-G. 收藏  |  浏览/下载：19/0  |  提交时间：2013/03/25 Data mining has become increasingly critical for the success of companies in this emerging era of Engineering Management. As Engineering Management activities increasingly shift to the web  the challenge facing corporate management is maintaining competitive advantage by building strong relations with employees  customers  and suppliers and partners. A good data mining strategy can help achieve this goal. Unfortunately  many companies use data mining technologies that do not suit today's new information era. This paper addresses the definitions about data mining  area of data mining  development of data mining  then provide an summary of the driving and impeding forces that help and hinder proper deployment of data mining strategies in Engineering Management. Finally  the paper advocates the strategy of data mining for Engineering Management. 2009 IEEE.   Photonic micro and sub-micro structures in LiNbO3 crystals (EI CONFERENCE) 会议论文 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China Wang P.; Bentini G. G.; Bianconi M.; Cerutti A.; Chiarini M.; Mazzoldi P.; Pennestri G.; Sada C.; She L. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 High energy lasers processing of materials is knowing an increasing interest since it not only can make manufacturing faster  cleaner  and more accurate but also because it opens up entirely new technologies and manufacturing methods  that are simply not available by using standard techniques. In this paper  an experimental set-up  based on pulsed KrF excimer Laser  assembled for surface patterning of mono and two-dimensional  (1D-2D)  micro and submicro structures on LiNbO3(LN) crystal  will be described in detail. The apparatus has been used to produce photonic structures in LN  both by patterning of PMMA photoresist  and by direct surface patterning through laser ablation or direct laser writing. The structures and properties of the photonic crystals fabricated by using this apparatus have been investigated  and the preliminary results will be presented.
