In order to further reduce the sulfur content in gasoline, a new desulfurization process was proposed by using catalytic oxidation and extraction realized in an electrochemical fluidized reactor. The fluidized layer of loaded catalyst particles consisted of lead dioxide (PbO2. supported on activated carbon particles (PbO2.C) and the electrolyte was aqueous NaOH solution. The PbO2.C particle anodes could remarkably accelerate the electrochemical reaction rate and promote the electrochemical catalysis of sulfur compounds. The sulfur compounds were at first oxidized to sulfones or sulfoxides, which were then re- moved after extraction. The experimental results indicated that the optimal desulfurization conditions were as follows: The cell voltage was 3.2.V, the concentration of hydroxyl ions in electrolyte was 0.12.mol/L, and the feed rate was 300 mL/min. Under these conditions the concentration of sulfur in gasoline was reduced from 310 ppm to 70 ppm. Based on these experimental results, a mechanism of indirect electrochemically catalytic oxidation was proposed.

Based on the characteristics of radarsignal processing, this paper presens a new dataflow drivenmechanism for high speed radar signal processing. Thismechanism has been successfully applied in an experimentalsystem (DSM), which is a general parallel software radar signalprocessing computer. For implementing this mechanism, thegeneration of dataflow tables during the compiling process isstudied in detail with a sample program.

The photosensitization effects of the benzophenone derivatives having different charges, such as cationic BP（BP—CH2.N+ （C2.5）3Br-）（PKT-1）, anionic BP（BP—COONa） and the neutral BP in the various ionic micellar systems were studied. From the photopolymerization of MMA initiated by the various BP/TEA in different micellar systems, the results obtained show that the polymerization rate is in the order of PKT-1>BP>BP—COONa in the SDS anionic micelle. On the contrary, the order changes to BP—COONa>BP>PKT-1 in the CTAB cationic mieelle, and to BP—COONa≈PKT-1>BP in the PKT-3 functional micelle. It is noteworthy that the PKT-1/SDS system is more efficient with its quantum yield more than 50 times compared with that of simple BP/H2. system.

This paper discussed two methods to enhance the electrical conductivity of the carbon fiber（CF） electrically conductive concrete. The increase in the content of stone and the amount of water used to dissolve the methylcellulose and marinate the carbon fibers can decrease the electrical resistivity of the electrically conductive concrete effectively. Based on these two methods, the minimum CF content of the CF electrically conductive concrete for deicing or snow-melting application and the optimal ratio of the amount of water to dissolve the methylcellulose and marinate the carbon fibers were obtained.
