	Tribological properties of Mos2 thin coatings under liquid lubricating (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Innovation Manufacturing and Engineering Management, IMEM 2012, December 14, 2012 - December 16, 2012, Chongqing, China Bai Y.; Cao P. 收藏 \| 浏览/下载：34/0 \| 提交时间：2013/03/25 The objective of this study is to investigate the effect of solid and liquid lubrication on friction and wear performance of selected solid lubricating coatings comparative experiments have been carried out on magnetron sputtered MoS2 coatings against Si3N4 ball using a ball-on-disk tribo-tester under the conditions of room temperature and different lubrication. Surface morphology of coatings were investigated by atom force microscope (AFM) and friction coefficient (COF) and wear rate of solid films were also be analyzed. It was shown that the friction is greatly reduced when the solid film is lubricated with oil and grease simultaneously in comparison with single-lubricant lubrication at the start-up or under boundary lubrication conditions. Liquid lubrication causes a dramatic decrease of the wear-ability of the MoS2 coatings. The effect of oil lubrication to the deterioration of wear resistance of MoS2 film was even worse than lubrication grease. (2013) Trans Tech Publications Switzerland.

	Spaceborne laser interconnect technology based on human bionics (EI CONFERENCE) 会议论文 OAI收割 2009 IEEE International Conference on Mechatronics and Automation, ICMA 2009, August 9, 2009 - August 12, 2009, Changchun, China 作者: He X.; Wang J. 收藏 \| 浏览/下载：33/0 \| 提交时间：2013/03/25 As a result of comparative study on human visual and Free Space Optical (FSO) communication a new concept of satellites laser interconnect was proposed based on human bionics. For the laser link is difficult to set up directly a new concept was given out based on the three processes of human visual capturing the objectives: voice assisting to guide eyes' wide Field Of View (FOV) cursory capturing and eyes' foveal FOV high-resolution imaging. Three similar processes were introduced to spaceborne laser interconnect which were radio assisting to guide beacons laser wide FOV capturing and communication laser narrow FOV capturing so that the difficulty of setting up the optical communication link was reduced evidently. Meanwhile the antenna optical system based on the bionics was given out. Each laser terminal configured two independent optical antenna through the spaceborne storage and time-domain link switching complex topology network could be set up. The simulation system was built using Virtual Reality Toolbox the result showed that the laser terminal could search and set up communication links which took about only lOOms from capturing the beacon to setting up communication. 2009 IEEE.
