In this paper, we studied the properties of speckle, which is produced by passing the radially polarized vortex beams through the scattering medium. We first of all study the generation of the radially polarized vortex beams. The experimental results show that the generated light beams possess the orbital angular momentum (OAM) and the polarization is of radial direction. The radially polarized vortex...
Effective dehalogenation by nanoscale zerovalent iron (nZVI) has been reported. In this study, the effects of Ni2+, Cu2+ ions, and the nonionic surfactant Tween-80 on dechlorination of 2,2’,5,5’-tetrachlorinated biphenyl (PCB-52) by nZVI were investigated in aqueous solution. The rate of dechlorination was significantly enhanced by Ni2+, while Cu2+ had a less significant catalytic effect. Ni2+ and...
Automatic Generation Control (AGC) testing diagnostic analytic system of power grid is used for AGC test between grid dispatching center and the power generator set. It is also for collecting, processing, analyzing and evaluating the generator set's testing data. Eventually a set of assessment results can be achieved. This system is mainly used for testing, diagnosing and evaluating the functions...
Building information technology includes production process information technology and management information technology. The first one can improve efficiency and productivity, and the other one can improve the business treatment efficiency and management level. In this paper, combining with the application requirement of building construction, application research o virtual simulation technology...
