ICCD is one of the opto-electronic image sensors, commonly used in neutron low-light-level imaging system and the coupling of CCD and Image-Intensifier is the key technology in ICCD. This paper discussed the structure of ICCD, and simulated the coupling of relay lens, cone fibers and grin lens based on ZEMAX. We analyzed and checked their parameters such as geometric image, MTF, coupling efficiency, etc. Experimental results show that: The coupling of relay lens has high image quality; the coupling of cone fibers has high coupling efficiency; the performance of grin lens falls in between.

Based on adaptive backstepping nonlinear control scheme and dissipative system theory, the robust adaptive nonlinear controller is designed for single machine infinite bus (SMIB) power system with static Var compensator (SVC), which conquers the obstacle of relative degree one of passivity feedback scheme. During the procedure of designing controller and parameter estimator, the uncertainties of disturbances and the damping coefficient are taken into account; therefore, the designed controller has the ability of robustness and adaptive estimation. The globally uniformly boundness of all the states in the system and the asymptotical stability of the system errors are verified by the theories. Simulation experiments show that not only the transient stability of the SVC power system is guaranteed, but also the robustness performance is significantly improved even with disturbances.

The aims of this work were to make use of carbonic materials to remove nitrobenzene in wastewater and investigate adsorption mechanism. The adsorption ability of different carbonic materials for nitrobenzene was compared. It was found that carbon nanotubes and carbon black exhibited higher adsorptive capacity than coconut activated carbon and granular activated carbon at the same experimental conditions. The specific surface areas and pore distribution was obtained by low-temperature nitrogen adsorption-desorption. We concluded that the capillary condensation in mesopores played an important role in the adsorption process owing to special nanostructure of carbon nanotubes and carbon black.
