Over the past several years , the modeling and control of flexible space robots have attracted much serious attention . compared with the conventional rigid robots , flexible robots have the potential advantages of lower energy consumption , large work volume and greater payload - to - manipulator weight radio 近年来,空间柔性机器人的建模和控制受到了广泛的研究,与传统的刚性机器人相比,柔性机器人具有耗能小、操作空间大、负载重等特点。
In order to get distributors more familiar with the performance of secco polyolefin products , to expand the influence of secco polyolefin products in the market and also to widen the marketing chances of secco polyolefin products , polyolefin business team of commercial department organized the technical training & communication workshop regarding po distributors for the y2007 as schedule 为了提高分销商客户对赛科公司聚烯烃产品质量的认识，拓展聚烯烃产品在市场上的影响力，从而提高聚烯烃销售的操作空间，商务部聚烯烃业务团队组织了2007年度聚烯烃分销商技术培训和交流。
In the whole bonding application , bond targets ’ identification and orientation are the most important aspects for full - automation . this dissertation introduces zoom microscope into the microscope positioning system to settle the contradiction between microscope ’ s visual range and depth of field . multiple scale images go through various image processing , and finally different bond targets are identified and positioned 将采集得到不同放大倍数时键合器件的清晰图像经过各种图像处理程序识别并分离出键合目标,通过一种“全局粗定位、局部精定位”的坐标变换方式完成了键合目标在操作空间中的精确定位。
Thirdly , based on the geometrical differential constraints and force balancing constraints of the coordinated flexible manipulators , the mutual relationships between the kinematic and dynamic parameters in static configuration have been presented . the manipulation stiffness of the coordinated system has also been proposed . the manipulability of the flexible robot system has been then analyzed in two aspects : i ) the global characteristics in the manipulation workspace based on the manipulation stiffness ; ii ) the local property of the reachable boundary of generalized forces 然后，利用柔性机器人协调抓取的几何微分约束和力平衡约束，通过深入分析系统在静态位形时其内部各运动参量和力参量之间的关系，定义了系统的操作刚度，从两个方面对系统的操作性能进行了分析： 1 ）操作空间中，基os于系统操作刚度的全局特性； 2 ）在一定约束的条件下，系统操作力矢端可达二边界的局部特性。
The most outstanding function of this wheelchair is its height which can be regulated with user ' s requirements . this function helps expand the user ' s available space , supplement the user ' s body defect and reduce the caregiver ' s burden . it get more improved than previous products . besides , the wheelchair has designed both manual and eletric mode . on one hand , it can save user ' s energy and power , on the other hand it won ' t leave users hopeless in case of powering off and relieve the user ' s worriness . in addition , the bigger basket on the tail part of the wheelchair provides the great convenience for user ' s carrying goods . multiangular back and height - regulated pedal add comfortableness to users . the minidesk with the wheelchair is very convenient for users to read , write and do other things 本设计的多功能轮椅最突出的一个功能就是座位的高度可以根据使用者的需求随意进行调节，这样就可以大大扩展使用者的操作空间，补充了使用者在身体上的缺陷，也可以减轻照顾人员的工作负担，比起以前的产品有了较明显的改进；其他功能还有轮椅的手动电动两种驱动方式，这样可以解决老年人和残疾人在体力上存在的问题，同时在外出时遇上没电的情况也不至于显得无能无力，消除了使使用者在长途奔波时的顾虑；此外位于轮椅尾部的超大储物筐，给使用者携带物品带来了极大的方便，靠背的多角度调节，脚踏板的高度调节大大增加了使用者的使用舒适度，轮椅上小桌的设计给使用者读书，写字，进行其他活动带来了极大的方便。
Because the press is being marketed as well as enter wto , facing the competition of the transnational media enterprises , there some figures in the mass media , using the experience of developed countries for reference , raise an urgent question that horizontal & vertical concentration is largely favored as an important element of mass media . at the meantime , reform in china during the last 20 years has provided a favorite environment for this practice 随着国内媒介市场化进程的加快，以及中国加入wto ，媒介面临着实力雄厚的大型跨国传媒集团的挑战，一些有识之士借鉴国外媒体的发展经验，提出跨媒体传播势在必行，同时国内改革的大环境已为跨媒体传播的实现提供了操作空间。
