Dual-Wavelength Linearization of Radio-over-Fiber Link for Broadband Access and Ubiquitous Sensing

引用

China Communications 2012年第1期9卷 20-24页

作者： Wu Zhongle lv qiang Dai Yitang Lin Jintong State Key Laboratory of Information Photonics and Optical Communications Beijing University of Posts and TelecommunicationsBeijing 100876P.R China

Radio-over-Fiber （RoF） technologies have been considered to be a promising solution to broadband access and ubiquitous sensing. We present a novel approach using dual-wavelength lights to suppress the nonlinear intermodulation distortion in intensity-modulated RoF link both theoretically and experimentally. The system we proposed rminly consists of two Laser Diodes （LDs） at different wavelengths, a commercial available Mach-Zehnder Modulator （MZM） and a Photo Detector （PD）. More than 25 dB suppression of the Third-order Interrnodulation Distortion （IMD3） is achieved by adjusting the wavelength and opti- cal power of the laser. Besides, the output of the MZM is then sent to the photodetector via a single fiber, which simplifies the system complexity for distrbution of RF signals over long distances.

Localized Corrosion of Binary Mg-Ca Alloy in 0.9 wt%Sodium Chloride Solution

Acta Metallurgica Sinica(English Letters) 2016年第1期29卷 46-57页

作者： Rui-Qing Hou Chen-Qing Ye Cheng-Dong Chen Shi-Gang Dong Miao-qiang lv Shu Zhang Jin-Shan Pan Guang-Ling Song Chang-Jian Lin State Key Laboratory for Physical Chemistry of Solid Surfaces College of Chemistry and Chemical EngineeringXiamen University Department of Chemistry Ningde Normal University College of Energy School of Energy ResearchXiamen University Division of Surface and Corrosion Science Department of ChemistryRoyal Institute of Technology College of Materials Xiamen University

To further understand the localized corrosion of magnesium alloy, various in situ electrochemical techmques and ex situ electron microprobe analysis and SEM were used to monitor the corrosion process of Mg-l.0Ca alloy in 0.9 wt% sodium chloride solution. The results indicated that the localized corrosion was accompanied by the formation and thickening of a corrosion product film on the Mg-l.0Ca alloy. A localized corrosion of the alloy initiated selectively on the eutectic micro-constituent zones, then enhanced with the exposure, developed in depth with ring-shaped corrosion products accumulated around and finally formed a volcanic-like pitting. Based on the measurements, an electrochemical corrosion model was proposed accordingly to describe the formation mechanism of the volcanic-like pitting on the alloy in 0.9 wt% sodium chloride solution.

Eigenstructure assignment in a class of second-order dynamic systems

控制理论与应用（英文版） 2006年第3期4卷 302-308页

作者： Guosheng WANG qiang lv Guangren DUAN Department of Control Engineering Academy of Armored Force Engineering Beijing 100072 China Center for Control Theory and Guidance Technology Harbin Institute of Technology Harbin Heilongjiang 150001 China

Eigenstructure assignment using the proportional-plus-derivative feedback controller in a class of secondorder dynamic system is investigated. Simple, general, complete parametric expressions for both the closed-loop eigenvector matrix and the feedback gains are established based on two simple Smith form reductions. The approach utilizes directly the original system data and involves manipulations only on n-dimensional matrices. Furthermore, it reveals all the degrees of freedom which can be further utilized to achieve additional system specifications. An example shows the effect of the proposed approach.
