The system gets two image of one object with two CCD, thus obtains depth from two CCD"s parallax. After investigating the operation spot and discussing with surgeons we use LED as markers, and get the marker"s 3-D position with a non-contact optics orientation method. After calibrating the CCD, processing the image, the system can figure out marker"s areal coordinates, get marker"s 3-D coordinate in dummy world coordinate system, thereby obtain instruments 3-D position and orientation. After the coordinate transformation and a series of orientation calculation, operation navigation comes true.

运用两个摄像机对同一目标从不同位置成像，进而从视差中恢复距离；通过对手术现场的仔细了解与手术医师的反复商榷，使用LED作为标志点，利用非接触式光学定位方法提取空间点位置信息：通过对摄像机的标定、图像处理及目标点重心的计算，求出空间点在虚拟世界坐标系下的三维坐标，从而确定了手术器械等的空间位姿，通过空间坐标转换及一系列定位计算，完成了手术导航实验系统。

Another my hep network celebrity is herd of Zhao of chief editor of Sohu rich guest, he is following after Olympic Games torch delivers Mount Everest, urgent go to Sichuan disaster area continuously, his a few individual discovery also make we think over somewhat, rescuing disaster area of 100 thousand main forces, but our spot comes to help the tool tries to do a difficult job as best one can however, what the person that a lot of coming to help uses is club of a root, the tool efficiency that rescuing team of it and major uses is having great difference of course.

另一位我熟知的网络名人是搜狐博客主编赵牧，他在跟随奥运火炬传递珠峰后，紧急直赴四川灾区，他的一些个人发现也使我们有所反思，十万大军救援灾区，但我们的现场救援工具却勉为其难，许多救援者使用的是一根根木棍，它与专业救援队使用的工具效率当然有着天壤之别。

Pre-stressed composite space truss is one of the new kind of space structure systems developed on the basis of prestress and space truss, which consists of steel and reinforced concrete. At present the study in this field is just being begun in our country. Therefore, in this paper static and dynamic performances of pre-stressed composite space truss associated with a practical engineering are studied, in addition, dynamic test on construction site and model experiment are done. Finally, we conclude this structure is well in stress and stiffness and dynamic characteristics.

预应力组合网架是一种基于网架和预应力技术发展起来的由钢和钢筋混凝土组合而成的新型预应力空间结构体系，目前国内在此领域的研究和应用都较少，为此，本文结合实际工程对预应力组合网架进行了静力和动力的分析研究，并作了施工现场的动力测试及模型试验，总结出预应力组合网架受力比较合理，刚度、动力特性好，是值得推广的一种空间结构形式。

As part of THERE IS NO I IN TEAM's international tour, this 3-day event happening at PROGRAM, Berlin, from 15th to 17th October 2009 brings together cutting-edge CHINESE VIDEO, LIVE AUDIOVISUALS AND PERFORMANCE ART and creative communities from both China and Berlin.

作为《只有团体没有个体》国际巡回展的一部分，这个在德国柏林"程序"项目基地举行的活动将持续三天，从2009年10月15日至17日，它为观众们带来最前沿的中国录像艺术、现场视听艺术和表演艺术，将中国和柏林的创意团体融汇一处。

This system has function dispersion and can deal withparameter checking, calculation, control strategy, information output andprocess parameters time-control. These functions will auto-run effectuallyand reliably that make control dispersion.

在此理论基础上，论文提出了一种应用于印刷业张力联动控制的基于现场总线技术的集散控制系统DCS2000-MRT，介绍了该系统的主要功能、硬件组成、工作原理、软件设计及其实现方法。

Host controller and multiple-site controller using asynchronous serial communication, or "soft-serial" in accordance with the "communication protocols" to achieve branch communications, computer controlled multi-component of "Distributed Control" system, according to three Flop flip side of the control sub-drive motor, to achieve large-scale three sides of the sign face will be over the screen, time, optional flip way, the sign face of an error "automatic error correction flip" and drive the requirements.

主控制器和多个现场控制器之间采用异步串口通信或"软串口"按照"通信协议"实现分支通信，组成多微机联控的"集散式控制"系统。这种多微机联控系统极大地简化了控制电路的连线，简化了电气控制安装工艺与施工，在降低工程费用和后期维修费用的同时，可大幅提高控制系统工程的可靠性、稳定性、性价比。
