The effects of biped physical parameters on the stability property of passive gaits are studied by simulation experiments. The chosen parameters include the mass distribution  length of leg and slope angle. The stability property of passive walking limit cycles is used as criterion of optimization calculation  including the orbital stability described by eigen-values of linearized Poincare map and the global property described by size of attraction region. The simulation results show how the stability of limit cycle varies when physical parameters of the passive biped change. The work is useful to explore the inherent property of passive dynamic walking and can be used as an important instruction in the mechanical design of biped robots based on principle of passive dynamic walking.

A long focal length dynamic aim generator is applied to simulate the image motion and the variety drift angle  and to detect the precision of the image motion compensation machinery and the capability of the drift angle control system. The computer system is used to control the dynamic aim generator  accomplish the data processing  transmit and receive the data information. The seamless connection and the data transmission between the aim generator and the aircraft simulation devices are constituted. The command  parameter and drift angle data transmitted by the simulation devices are received by the space camera at the real time  then the photos are taken and the draft angle is adjusted simultaneously. It is shown that the drift angle can be accurately tracked by the space camera at the real time  and the detective method satisfies the test requirement. 2010 Copyright SPIE - The International Society for Optical Engineering.   Boundary conditions at the solid-liquid surface over the multiscale channel size from nanometer to micron 期刊论文  iSwitch采集 International journal of heat and mass transfer, 2007, 卷号: 50, 期号: 13-14, 页码: 2571-2581 作者:  Xu, Jinliang 收藏  |  浏览/下载：26/0  |  提交时间：2019/05/10 Boundary condition  Slip length  Interfacial parameter  Channel size   Boundary conditions at the solid-liquid surface over the multiscale channel size from nanometer to micron 期刊论文  OAI收割 international journal of heat and mass transfer, 2007, 卷号: 50, 期号: 13-14, 页码: 2571-2581 作者:  Xu, Jinliang;  Li, Yuxiu 收藏  |  浏览/下载：83/18  |  提交时间：2010/09/27 boundary condition  slip length  interfacial parameter  channel size   Dispersion compensating properties of microstructure fiber (EI CONFERENCE) 会议论文  OAI收割 ICO20: Optical Communication, August 21, 2005 - August 26, 2005, Changshun, China 作者:  Li C. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 Microstructure fiber is a new kind of optical fiber. An arrangement of air holes running along the full length of the fiber provides the confinement and guidance of light. The light is confined in the silica core along the fiber axis. This fiber has endlessly single mode  special dispersion characteristics and so on. Using a vectorial effective-index numerical method  we investigated the dispersion characteristics of a microstructure fiber with honeycomb cladding structures. The dispersion  dispersion slope  and Kappa parameter can be designed neatly by changing the air hole size and the separation of the holes in fiber cladding. We demonstrated the Microstructure fiber with large absolute value of normal dispersion and negative dispersion slope at the wavelength of 1550nm. Conventional communication non-shifted single-mode fibers and nonzero-dispersion shifted fibers (NZ-DSF) can be compensated efficiently using the microstructure fiber at the wavelength around 1550nm.
