	Research on the torque characteristic of disc micromotor on axial magnetic field (EI CONFERENCE) 会议论文 OAI收割 2012 2nd International Conference on Consumer Electronics, Communications and Networks, CECNet 2012, April 21, 2012 - April 23, 2012, Three Gorges, China Liu B. 收藏 \| 浏览/下载：52/0 \| 提交时间：2013/03/25 In order to increase the electromagnetic torque density of micromotor with axial magnetic field numerical analysis of permanent magnetic field and electromagnetic torque were deduced and the key factors of increasing torque density of micromotor was obtained. The numerical analysis of three-dimensional magnetic field in air gap produced by spliced sector permanent magnetic poles is done and the way of improving flux density and permanent magnet use efficiency are given through investigating the influence of magnet thickness height of air gap and pole interval rate and other parameters to air gap flux density and leakage flux. Based on the test of axial magnetic field and torque characteristic of micromotor the analysis of micromotor magnetic field and calculation of torque are verified meanwhile using the plane stator with 0.7mm thickness assemble micromotor having minimum air gap height of 1mm and its torque constant up to 3.8mNm/A. 2012 IEEE.
	Brazing RB-SiC used in large aperture space optical system (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Materials and Products Manufacturing Technology, ICMPMT 2011, October 28, 2011 - October 30, 2011, Chengdu, China Zhang B.; Zhang Z. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 Because of the sic material's superior optical characteristic machine characteristic and hot characteristic it becomes currently the space big aperture reflector choose firstly1. For larger aperture sic mirror it is not economical and safe to make the monolithic body directly 2 3. The SiC mirror brazed assembly with several segments can solve these problems. In this paper one 600 mm sic plane mirror as demonstration welded with 3 radial segments is roughly grinded to the required figure at first then the mirror is finely grinded and polished by the technology of CCOS the mirror figure error is less than 1/20 ( = 632.8nm) in RMS finally. The problems of the preferential removal near braze joint are solved. The methods of reducing the residual stress of mirror are discussed. At last some measurements and experiments are carried on and the results conclude that the brazed SiC mirror can meet the requirement of large aperture optical systems.

	Input plane preprocessing of joint transform correlator based on Swarm Intelligence (EI CONFERENCE) 会议论文 OAI收割 2009 2nd International Congress on Image and Signal Processing, CISP'09, October 17, 2009 - October 19, 2009, Tianjin, China Yong W.; Ming Z. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 Input plane image preprocessing can improve the performance of Joint Transform Correlator(JTC). Swarm Intelligence based image processing method is consistent with the parallel characteristic of optical signal processing method. In this paper A Swarm Intelligence based input plane preprocessing method is proposed. Some other methods are also used to perform the task such as grayscale transform Sobel operator and mathematical morphology. The experimental results show that the performance of the proposed Swarm Intelligence preprocessing based JTC is better than that of the JTC based on other preprocessing methods. 2009 IEEE.
