	The design problems of one kind of chaotic one-way hash function (EI CONFERENCE) 会议论文 OAI收割 2012 4th International Conference on Multimedia and Security, MINES 2012, November 2, 2012 - November 4, 2012, Nanjing, Jiangsu, China Li P.; Zhang M.; Shi J. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 The construction method of one kind of one-way hash function based on 1-D Logistic map is analyzed. The design problem and some collision problems are pointed out. By using the dictionary attack the collision probability of the arithmetic realized with signal floating point numbers is 2-23 and the collision probability of the arithmetic realized with double floating point numbers is 2-55. The reasons for these design problems are discussed and some key problems are pointed out which should be taken care of while constructing one-way hash function based on a digital chaotic map. 2012 IEEE.
	Buffer and vibration optimization of missile data recorder structure (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronics and Materials Processing, ICMMP 2011, November 18, 2011 - November 20, 2011, Guangzhou, China 作者: Zhang J.; Zhang J.; Zhang J. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 On the analysis of the original data recorder the stress wave theory is the elastic theory can explain the filter buffer question from the micro-small space made several key problems clear when buffer and damping from this designed a composite structure for vibration reduction distinguished between a cushion theory and application field of stress wave theory which made the dynamic stress of protected component down about one order of magnitude. Optimization with Isight and Ls-dyna the traditional rigid spring-buffer model whose object is to reduce the impact of acceleration that can not accurately describe the elastic force of the part of the actual situation the protected component's dynamic stress down about 69.3% and the data recorder's quality 300g lower finally passed the Marshall Hammer test successfully. 2011 Trans Tech Publications.
	A sensitive solid-phase time-resolved fluorescence immunoassay apparatus (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging 2009: Laser Sensing and Imaging, June 17, 2009 - June 19, 2009, Beijing, China 作者: Song K.-F.; Li J.-L.; Zhang W.-L.; Wang Y.-L. 收藏 \| 浏览/下载：37/0 \| 提交时间：2013/03/25 In the device a He-Ne laser of flash frequency 1-20 Hz was adopted as exciting light source and three key technical problems have been solved successfully in order to enhance the detecting sensitivity and measuring stability of the device for time-resolved fluorimmunoassays(TRFIA) [1]. The first one is to design optimum exciting optical system so that the exciting light beam excite the sample most effectively. The second one is to have a project spectrum filter which can reduce the affection of the background light to the photomultiplier tube and also ensure influence of the stray light and mixed diffusion light to the sample fluorescence to the least the sample fluorescence through the integrating sphere and come to the grating monochromator The right wavelength will be chosed through changing the angle of incidence of the grating monochromator. The third one is to simulate the principle of sample averaging of BOXCAR averager. In the device SCM was used as primary controller and CPLD was used as timing controller. Through the preparation process signal-to-noise ratio(SNR) will be improved also adjust delay time ampling frequency and sampling number arbitrarily. By testing the sensitivity is 10-12mol/L(substance marked by Eu3+) examination repeat is &le2.5% examination linearity is from 10 -8mol/L to 10-12mol/L correlation coefficient is 99.98%(p&le0.01). The instrument is advanced for ultrasensitive detection of antigen and antibody and solve the tumor genetic variation the virus protein detection. 2009 SPIE.

	Grating interferometry method for torsion measurement (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China 作者: Liu W. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 Method of grating interferometry was presented for torsion angle measurement moire fringe generated by two gratings is used in a new field it breaks through moire fringe's routine application. Measurement principle is described torsion angle can be gotten by the tilt angle or the width of moire fringe. Different from moire fringe's characteristic information extracting methods in traditional measurement fields fringe-tilt method and fringe-width method were put forward to extract moire fringe's characteristic information. Fringe-tilt method is on the basis of moire fringe's tilt to acquire torsion angle uniform formula was built aiming at all positions of two gratings in the coordinates fringe-width method is on the basis of moire fringe's width to acquire torsion angle three key problems are given about fringe-width method. Thick middle and thin moire fringe were collected in experiments and processed by two methods fringe-width method's result shows that magnitude of boat torsion error is satisfied with that of theoretical precision analysis and the change rule of torsion error is also same to that of theoretical analysis the thicker fringe is the higher precision is when fringe width arrives to be 1695m the precision is 1.7" the thinner fringe is the lower precision is when fringe width arrives to be 734.7m the precision is 6.7". In addition to these the results of repeatability experiments sensibility experiments are given. In a word the measurement principle is right and the precision of fringe processing is also reliable.
